How to find the right Automotive Performance Chassis Trailing Arms AI guide

What the AI looks for in Automotive Performance Chassis Trailing Arms

Fixed vs. adjustable
Adjustable arms let you correct pinion angle, wheelbase or toe after a lift or drop. Changing ride height alters the geometry stock arms were designed for.
Joint choice
Rubber or poly bushings for street use. Rod ends or spherical joints for drag or track use. Stiffer joints sharpen the response but add noise and vibration and need maintenance.
Construction
Boxed or tubular steel replaces flexible stamped arms. Look for gussets at the bushing ends. On launch-sensitive cars, arm flex causes wheel hop.
Platform specifics
Match the chassis code and the arm position (upper or lower). Note whether the arm carries the sway bar or brake line mounts. Muscle car four-links, Jeep links and FWD rear trailing arms are all different parts.
Install at ride height
Torque the pivot bolts with the vehicle loaded at ride height. This prevents bushing preload and early failure.

Questions

Are trailing arms and control arms the same thing?

Often the terms are used loosely. On many rear axles the lower links are called trailing arms. Check the exact position in the fitment listing.
