Keystone MA4521100 Front Outer Tie Rod End RH OEM Replacement

The Keystone MA4521100 is an OEM-replacement front outer tie rod end for the right-hand (passenger) side, engineered to restore proper steering geometry and precise directional control. This part directly replaces Mazda OEM part number BP4L-32-280 and serves as a direct-fit, drop-in replacement with no modification required.

The outer tie rod end connects the inner tie rod to the steering knuckle, translating rack-and-pinion movement into controlled wheel direction. A worn or damaged outer tie rod end can cause loose or wandering steering, uneven tire wear, and wheel misalignment — making timely replacement essential for both safety and tire longevity.
