PMF Suspension Front Axle U-Bolt Kit, Square, 11.5 in — 1988–1997 Ford F-250 / F-350 — UBFSQ563-30-115

PMF Suspension square front axle U-bolt kit, 11.5 in legs, for the 1988–1997 Ford F-250 / F-350.

U-bolts are not reusable. They stretch when they are torqued, which is how they hold clamp load, and a second torque cycle does not put that back. New ones go in whenever the spring pack comes apart — and a lift almost always means longer ones.

U-bolts come in two bend profiles and the axle decides which one you need: square is what this kit supplies. Measure the leg length you need from under the spring plate, not from the old bolt if it has already been stretched.

This kit is the 11.5 in length. PMF list every length as its own part number at the same price, so order by measurement rather than by guess.

Fitting new U-bolts is cheap insurance on a job that is already apart.
