FAQ
Why replace the RZR Pro XP caliper pistons with stainless?
OEM composite pistons can turn brittle and chrome or aluminum pistons can corrode and stick. All Balls' 304 stainless pistons resist corrosion and carry less heat into the caliper.
What comes in the kit?
All Balls lists three caliper pistons.
Which models does it fit?
All Balls lists Polaris General XP 4 1000 (2020-2025); Polaris RZR Pro XP (2020-2026); Polaris RZR Turbo S (2018-2021); Polaris RZR Turbo S 4 (2020-2021); Polaris RZR Turbo S Velocity (2019-2021); Polaris RZR XP 4 Turbo (2016-2021); Polaris RZR XP Turbo (2016-2021).
Which position does it fit?
All Balls lists this part for the front position on the machines it covers. Confirm your exact year and model in the fitment list.
Is installation difficult?
The caliper is disassembled, the old pistons are pushed out and the new stainless pistons go in with fresh seals. A caliper rebuild kit is usually replaced at the same time. Bleed the brakes afterward. All Balls does not publish an install sheet for this part.
Do I need a caliper rebuild kit as well?
Usually yes. New seals and boots should go in with new pistons, so pair this with the matching All Balls caliper rebuild kit.
