Frame Machine Parts: Keep Your Collision Repair Equipment Working
A quality frame machine can remain productive in a collision repair shop for decades.
The challenge often isn't the frame machine itself.
It's finding the right replacement parts to keep it working.
Hydraulic cylinders eventually wear. Seals begin to leak. Tower components need service. Pumps fail. Switches, valves, and gauges stop working. Anchoring clamps, rollers, pins, chains, and other components wear out after years of daily collision repair use.
That doesn't necessarily mean it's time to replace the entire frame machine.
At Grade A Tools, frame machine parts are an important part of what we do. We manufacture replacement components for collision repair equipment while also supplying parts and equipment from other professional manufacturers.
In fact, Grade A Tools manufactures more than 500 products for the collision repair industry, giving us firsthand experience with the equipment, replacement components and everyday problems professional body shops encounter.
Whether you're maintaining a Chief, Car-O-Liner, American Freedom, Blackhawk or another frame machine, our goal is straightforward:
Help you find the part you need and get your frame machine back to work.
We Don't Just Sell Frame Machine Parts — We Manufacture Replacement Solutions
There's an important difference between simply listing frame machine parts and understanding how those parts are used.
Grade A Tools has developed and manufactured replacement products specifically for professional collision repair equipment.
Our frame machine replacement parts range from major assemblies to the small components that can bring an otherwise productive machine to a stop.
Depending on the machine and application, you'll find replacement:
- Hydraulic pumps
- Lift rams and cylinders
- Tower rams
- Hydraulic seal kits
- Tower collars
- Tower components
- Anchoring stands
- Pinch weld clamp components
- Clamp jaws and grips
- Hydraulic valves
- Pressure gauges
- Pendant switches
- Rollers and bearings
- Pins and retainers
- Springs
- Hydraulic fittings
- Hoses
- Hardware
- Other machine-specific service parts
For many applications, these are replacement / non-OEM components designed to replace the original part, allowing a shop to repair the equipment it already owns rather than replacing an entire frame machine because one component has failed.
Chief Frame Machine Parts
Chief frame machines have been part of the collision repair industry for decades, and many of these machines remain in daily service.
Grade A Tools has built an especially extensive selection of Chief frame machine replacement parts.

Chief Frame Machine Parts at Grade A Tools
Our current Chief frame machine parts section includes replacement components for machines such as:
- Chief EZ Liner II
- Chief Classic
- Chief S21
- Chief S21M
- Chief EZ-25
- Chief Titan
- Chief Goliath
- Chief Impulse eVHT
- Other Chief frame equipment
The selection goes well beyond a few generic hydraulic parts.
Grade A Tools offers machine-specific replacement components covering hydraulics, towers, lifting systems, anchoring equipment, controls, and smaller service parts.
Chief EZ Liner II Parts
The Chief EZ Liner II is a great example of why replacement parts remain important.
There are still EZ Liner II machines working in collision centers across the country.
If one develops a hydraulic leak, loses a pressure gauge, needs a tower ram or develops a problem with a tower collar, that doesn't automatically make the entire frame machine obsolete.
Grade A Tools offers replacement components specifically for these machines.
Replacement Chief EZ Liner II Tower Ram
The Replacement Chief EZ Liner II Tower Ram provides 5-ton pulling power with a 10-inch stroke and is designed as a non-OEM replacement for Chief part 602378.
It is compatible with Chief EZ Liner II, Classic, and S21 tower applications, along with certain other compatible frame systems.
Instead of replacing a complete pulling tower because of a failed hydraulic cylinder, the appropriate replacement ram can put the pulling system back into service.
Replacement Chief EZ Liner II Pressure Gauge
Sometimes the problem is considerably smaller.
The Replacement Chief EZ Liner II Frame Machine Pressure Gauge replaces Chief part 685011 and is designed for EZ Liner II frame machines.
It's a perfect example of why maintaining access to smaller service parts matters.
A frame machine may be structurally sound and mechanically productive but still require a relatively inexpensive component to operate correctly.
Replacement Chief EZ Liner Tower Collar
Grade A Tools also offers a Replacement Chief EZ Liner Tower Collar Assembly for EZ Liner II, Classic and S21 auxiliary tower applications.
Tower collars, rollers, pins and related components take significant wear over years of frame pulling.
Being able to service those individual components can help extend the working life of the equipment.
Chief Titan, Goliath & Other Frame Machine Parts
Our replacement parts coverage extends well beyond the EZ Liner.
For example, the Replacement Chief S21M & Titan Lift Ram is a dual-acting hydraulic replacement designed for Chief S21M and Titan frame machines.
Grade A Tools also offers the Replacement Chief Titan Front Tower Ram for the Titan front stationary tower.
For Goliath and Impulse eVHT equipment, the Replacement Chief Goliath / Impulse eVHT Tower Ram provides a 10-ton replacement solution for compatible applications.
This machine-specific approach is important.
A hydraulic cylinder isn't simply a hydraulic cylinder when it has to fit an existing frame machine correctly.
Mounting configuration, stroke, bore, hydraulic operation, and application all matter.
Frame Machine Hydraulic Pumps
The hydraulic pump is at the heart of many frame machines.
When it fails, an otherwise productive frame rack can become unusable.
Grade A Tools carries replacement frame machine hydraulic pumps for several systems, including applications associated with:
- Chief
- American Freedom
- Blackhawk
- Other collision frame equipment
We also carry professional hydraulic components from established manufacturers such as Power Team and OTC for appropriate applications.
This combination of Grade A Tools-manufactured replacement equipment and products from other professional manufacturers allows us to offer solutions for a much broader range of frame-machine repair needs.
Hydraulic Rams, Cylinders & Seal Kits
Hydraulic cylinders do a tremendous amount of work on a frame machine.
They're responsible for operations such as lifting the rack and providing pulling force through the towers.
After years of use, seals can wear and cylinders can eventually require repair or replacement.
Grade A Tools offers:
- Frame machine lift rams
- Tower ram cylinders
- Auxiliary tower rams
- Single-acting cylinders
- Dual-acting cylinders
- Hydraulic seal kits
- Replacement seals and wipers
- Cylinder-related service components
And a leaking ram doesn't necessarily mean the complete cylinder needs to be discarded.
Depending on its condition, the appropriate hydraulic seal kit may be all that's required to put it back into service.
Tower Parts: Repair the Components That Wear
Frame machine pulling towers are subjected to demanding loads throughout their service life.
That's why Grade A Tools doesn't stop at complete tower rams.
Our replacement selection also includes individual tower-related components such as:
- Tower collars
- Tower heads
- Tower chains
- Rollers
- Roller bearings
- Roller pins
- Retaining rings
- Washers
- Flanges
- Locking components
- Hydraulic components
- Related tower hardware
This gives collision repair shops the ability to service the part of the tower that actually needs attention rather than automatically replacing a much larger assembly.
Frame Machine Anchoring Parts
A frame machine can't perform a controlled structural pull unless the vehicle is properly secured.
Anchoring equipment is therefore just as important as the pulling tower itself.
Grade A Tools manufactures and supplies frame machine anchoring equipment and replacement components, including:
- Anchoring stands
- Tall anchoring stands
- Pinch weld clamps
- Serrated clamp jaws
- Grip screws
- Clamp springs
- Clamp bolts
- Mounting components
- Truck anchoring components
- Replacement anchoring hardware
Grade A Tools even offers small replacement components such as Chief-style anchoring clamp springs and serrated jaws/grip screws.
That matters because sometimes a shop doesn't need another anchoring system.
It just needs the right part to repair the one it already has.
Car-O-Liner Frame Machine Parts
Grade A Tools also has a dedicated selection of replacement components for Car-O-Liner frame machines and anchoring systems.
Shop Car-O-Liner Frame Machine Parts
Car-O-Liner Frame Machine Parts at Grade A Tools
Our Car-O-Liner replacement selection includes products such as:
- Hydraulic rams
- Hydraulic foot pumps
- Hydraulic hoses
- Truck frame anchoring equipment
- Tall truck mounting arms
- Pinch weld clamp bolt kits
- Truck anchoring clamp bolt kits
- Fastener plate bolt kits
- Pendant switch assemblies
- Pneumatic valves
- Solenoid valves
- Wedge nuts
- Distance spacers
- Mounting components
- Other machine and anchoring service parts
Many of these products are Grade A Tools-branded replacement components designed to keep existing Car-O-Liner equipment in service.
For collision centers with a significant investment in Car-O-Liner equipment, having another source for these replacement components can be especially valuable.
American Freedom & Blackhawk Frame Machine Parts
Grade A Tools also supports other frame machine systems.
Our selection includes replacement components for American Freedom frame machines, including hydraulic pumps, rams and tower-related service parts.
We also carry replacement parts for Blackhawk frame machines and Power Pro equipment, including hydraulic pumps, lift and tower components, rollers and other service parts.
This is an important part of our approach to frame-machine repair.
We aren't building the catalog around one machine.
We're building it around the needs of collision repair shops that want to keep good equipment working.
Don't Replace a Frame Machine Over a Small Part
It's easy to focus on hydraulic pumps, rams and anchoring systems because they're major components.
But some of the most useful replacement parts in our catalog are much smaller.
A machine can be affected by a worn:
- Seal
- Wiper
- Snap ring
- Roller
- Pin
- Spring
- Washer
- Clamp jaw
- Grip screw
- Valve
- Switch
- Gauge
- Hydraulic fitting
- Hose
- Retainer
- Fastener
Grade A Tools carries frame-machine components ranging from major hydraulic assemblies all the way down to individual washers, retaining rings and clamp springs.
Sometimes the difference between a frame machine sitting idle and going back to work is one small replacement part.
Why Repair the Frame Machine You Already Own?
Frame machines represent a significant investment.
Many collision repair centers have racks that have been productive for years—or decades.
The technicians already understand them.
The shop is already configured around them.
And in numerous instances, the machine itself remains perfectly serviceable.
If the problem is a hydraulic pump, worn ram, leaking seal, damaged tower component, broken switch, worn anchoring clamp, or failed valve, replacing the entire frame machine may not be necessary.
Repairing the existing equipment can make sense when the machine still meets the shop's requirements and the appropriate replacement components are available.
That's precisely why Grade A Tools continues to manufacture and source these parts.
More Than a Parts Reseller
There's another reason we take frame-machine replacement parts seriously.
Grade A Tools manufactures more than 500 products for the collision repair industry.
We're not simply adding generic parts to an online catalog.
Our manufacturing experience gives us a practical understanding of professional collision repair equipment and the replacement components shops need to keep that equipment productive.
We manufacture replacement solutions while also working with established professional brands when their products are the appropriate choice.
That combination allows Grade A Tools to support collision repair facilities with everything from small service components to major hydraulic and anchoring equipment.
Can't Identify the Frame Machine Part?
This happens more often than you might think.
Older machines may have missing labels.
Part numbers may have changed.
A previous owner may have modified or repaired the equipment.
Or you may simply have a broken component in your hand without knowing its name.
Contact Grade A Tools.
When possible, have information such as:
- Frame machine manufacturer
- Machine model
- Approximate age
- Original part number
- Photos of the existing component
- Photos showing where the component mounts
- Measurements when applicable
That information can make identifying the appropriate replacement much easier.
We're here to do more than put a box on a truck.
We want to help you find the right part and get your equipment back into production.
