Frame straightening
Frame straightening is the structural process of returning a car's chassis or unibody geometry to factory specification after a collision has bent or shifted it.
What it means
Modern cars are unibody construction: the body shell IS the chassis, with structural rails, pillars, and reinforcements forming a single load-bearing assembly. A serious collision can shift that geometry: rails get pushed back, pillars lean, suspension mounting points move out of true. The car may still look broadly correct but the wheel alignment refuses to hold, doors close unevenly, and panel gaps stay off no matter how many times they are reset. Frame straightening solves this with a calibrated jig: the car is anchored to a fixed reference frame, hydraulic pulls and pushes apply force to the affected structural members, and laser or computerised measurement systems compare the result against the manufacturer's spec until the geometry is back within tolerance. The work is specialised, slow, and requires equipment that not every bodyshop owns. After frame work, the car gets new wheel alignment, panel adjustment, and a thorough quality check.
Why it matters in Singapore
Singapore collision repair customers often discover the frame-straightening question only after a major collision. A bodyshop that does not have its own frame jig either subcontracts the work or skips it, and skipping it is what produces the post-repair cars that pull, wear tyres unevenly, and never feel quite right again. Asking about frame-straightening capability is a reasonable question for any major-collision quote.
How Revol Carz handles this
Revol Carz handles frame-straightening on its own jig with laser measurement, restores geometry to manufacturer spec, and follows up with four-wheel alignment and panel adjustment.
