Frame Straightening and Structural Repair

Frame work is a measurement discipline. We record the chassis geometry against factory specification first, identify exactly where and how far it has moved, and plan the pull sequence from that data. Pulling a rail without measuring is how a shop turns one bent section into two.

After correction we measure again and keep both records. That documentation matters for the insurance claim and it matters at resale, because a buyer who can see the before and after numbers treats the repair very differently than one who is told to take it on faith.

Not every damaged rail can be straightened. Metal that has been stretched, kinked at a sharp angle, or cracked will not return to specification and will not hold if forced. In those cases we section the rail, which means cutting out the damaged segment and welding in new material at an engineered splice location.

Splice placement matters enormously. Putting a joint at a high stress point creates a failure waiting to happen. We place splices where the manufacturer's structural guidance allows and we reinforce according to that guidance rather than improvising.

Not all frame damage comes from a collision. Sustained overloading, hard towing duty, and years of stop-and-go route work all put fatigue into a chassis. That shows up as sag, cracks radiating from mount holes, or ripples in the rail web.

Fatigue damage is repairable but the repair only lasts if the underlying cause is addressed. If a truck is bending its frame because it is running consistently over its rating, the frame will bend again.
