What the AI looks for in Automotive Replacement Control Arm Shaft Kits
- Vehicle application
- Cross-shaft kits are for upper control arms that pivot on a shaft bolted to the frame, mainly older GM, Ford and Mopar cars and trucks Most modern vehicles use bolt-through bushings with no shaft, so check your arm design before buying.
- Kit contents
- A complete kit includes the shaft, both bushings, and the end washers and nuts or bolts Reusing worn or rusted shaft hardware defeats the rebuild.
- Alignment shims
- Record the location and stack of camber and caster shims before you remove the shaft, then refit them the same way Most of the alignment on these suspensions is set by shims at the shaft mounts.
- Offset shafts
- Offset shafts are available for some applications to extend caster or camber range They help lowered, lifted or modified vehicles that can't reach alignment specs with stock shafts.
