Shop heavy-duty truck frame machines built for fleet shops, bus depots and commercial truck repair centers. Star-A-Liner HD truck frame racks come in 27', 40', 50' and 60' lengths with 6 to 14 pulling towers, so you can straighten frames on semi trucks, buses, box trucks and other large commercial vehicles that won't fit on a standard collision rack.
Every tower in the HD line delivers 25 tons of hydraulic pulling power with a full 360° pulling radius, and the 102" bed width handles wide commercial chassis.

Heavy-Duty Truck Frame Racks for Commercial Repair
A truck frame machine works like a standard auto body frame machine, scaled up for commercial vehicles. The vehicle is anchored to a long, rigid bed while multiple hydraulic towers pull bent frame rails back to specification. Because semis, buses and heavy trucks are longer, heavier and wider than passenger vehicles, a heavy-duty truck frame rack needs a longer bed, more pulling towers and more pulling force than a collision rack built for cars.
How to Choose a Truck Frame Machine
- Bed length: Match the rack to the longest vehicles you repair. A 27' rack suits shops that take in a truck or bus occasionally. 40' and 50' racks handle most semis and buses, and a 60' rack fits the longest commercial vehicles without overhang.
- Number of towers: More towers mean more pulling points along the frame, so you can make pulls along the full length of the vehicle instead of just at the ends. The HD line runs from 6 towers (27') to 14 towers (60').
- Shop space: Plan for the footprint with towers extended, not just the bed. Towers extended, the racks measure 201.5" wide, and overall height is about 11' 8.5".
- Power: The hydraulics on Star-A-Liner HD racks run on standard 110V / 15 amp power, so you don't need specialized electrical service for the pulling system.

Truck Frame Machine FAQs
What is a truck frame machine?
A truck frame machine, also called a heavy-duty truck frame rack or truck frame straightening machine, is a frame rack sized for semi trucks, buses and other commercial vehicles. It anchors the vehicle and uses multiple high-capacity hydraulic towers to pull damaged frame rails back into alignment.
How much does a heavy-duty truck frame machine cost?
Our Star-A-Liner heavy-duty truck frame racks currently range from about $130,000 for the 27' HD-27 to about $276,000 for the 60' HD-60. Price depends mainly on bed length and number of towers. Request a quote for exact pricing, including freight.
What size truck frame rack do I need?
Choose a bed at least as long as the longest vehicles you regularly repair. Shops that see trucks only occasionally often start with a 27' rack, while fleet, bus and specialty truck shops typically need 40' to 60' to work on full-length vehicles without overhang.
How much floor space does a truck frame machine need?
Plan for the full footprint with towers extended: from about 33.5' long for the HD-27 up to about 66.5' for the HD-60, and roughly 201.5" (16.8') wide. Leave extra room around the rack to move towers and work safely.
How much pulling power do heavy-duty truck racks have?
Each tower on the Star-A-Liner HD line is rated for 25 tons of hydraulic pulling force with a 360° pulling radius, so you can pull from any direction along the frame.
