Upper and Lower A-Arm Ball Joint Rebuild Kit ALL BALLS (manufacturer part number 42-1051) designed for Polaris RZR. This kit is designed to renew the joint of an A-arm ball joint (upper or lower), allowing you to replace worn components without changing the entire arm. Ideal for reducing play and achieving sharper steering of the front end on tracks, trails, or technical paths.
This kit is aimed at quad owners who wish to maintain their front end without replacing the entire A-arm. During reassembly, check the play, the condition of the threads, and follow the torque specifications recommended by the manufacturer. Compatible with POLARIS RZR 1000 XP models (including TURBO and 4 EPS versions) from 2017 listed in associated equipment. Replace the worn ball joint to restore reliable steering behavior and reduce unwanted vibrations.
