Standard coil lift basics
A standard coil lift raises the truck by swapping in new coil springs and related hardware while keeping the original suspension layout. That approach is familiar to most shops, but it still changes ride height, which affects steering geometry, brake hose length and the angle of the driveshafts. The front end should be aligned after the install, and the steering should be checked for play.
Replacement lift springs and extended bump stops work as a set, so a worn bump stop can undo some of the benefit of a new spring. Inspect the coils for cracks and the bump stops for cracking or flattening. Brake lines should be checked at full droop and full compression. If the truck is driven off road, check the mounts after each trip for early signs of wear.
- Check steering play after the first drive
- Look for cracks in the coil springs
- Confirm brake line clearance at full droop
