Serviceable Parts

FK uniballs in the sizes our kits use — 7/8" (WSSX14T), 1" (AIN16T), 1.25" (COMH20T, 2.375" OD), 1.5" (COMH24T, 2.75" OD) and the .750 bore FKS12T. PTFE-lined rod ends in 3/4" left hand, 7/8" right hand, 1.25" with 1" ball, and 7/8" with 7/8" ball.

The spacer is usually what you actually need. We stock them by application and part number, including Gen 1, Gen 2 and Gen 3 Raptor lower arm frame spacers, upper ball joint spacers for 1.5" uniballs, tie rod taper spacers for Raptor and Ram TRX spindles, Bronco Raptor lower arm ball joint adapters, TRX front upper and lower arm spacers, and 3/4" and 7/8" rod end spacers for Raptor upper arms at the frame.

Billet aluminum top caps for our billet upper control arm kits, in raw, black, blue and FOX orange anodized. Uniball top caps for 1.5" uniballs in buried-bolt and 12-point versions. Long and short side spacers for Bronco billet upper arms. Urethane wobble stoppers in .5" and .75" widths.

Replacement HDPE skids for Bronco and Bronco Raptor rear lower arm guards — the plastic is designed to be the sacrificial part, so you replace it and keep the guard. Factory race 2.5 x 2.45 bump stops. Replacement parts for FMI Raptor upper control arms.

How do I know which uniball or spacer I need?

Match the part number if you have it — most of our service parts carry an FM-prefixed number that appears in the product title. If you do not, tell us the vehicle, which Foutz kit is installed and where the part sits, and we will identify it.

How often should uniballs be replaced?

It depends entirely on use. A desert truck may need them annually; a street-driven truck may go for years. Play in the joint, noise over bumps or visible wear on the ball are the signals.

Do you sell rebuild kits for the upper arms?

Yes — see Replacement Parts for FMI Raptor Upper Control Arms, plus the individual uniballs, spacers and top caps listed here.

Are these parts for Foutz kits only?

The FK uniballs and PTFE rod ends are standard industry sizes and get used across many builds. The spacers, top caps and adapters are specific to our kits.
