PRO R Trailing Arm Gusset Kit

The Polaris PRO R / Turbo R Trailing Arm Gusset Kit is designed to address known weak points in the factory trailing arms that can bend, crack, or fail under aggressive riding and racing conditions. This reinforcement kit adds precision-cut 4130 chromoly gusset plates to critical stress areas, significantly increasing strength and durability without changing suspension geometry.

Polaris PRO R and Turbo R models are heavy, powerful machines, and the stock trailing arms are prone to fatigue when subjected to hard landings, rock impacts, desert racing, or high-speed trail abuse. This gusset kit strengthens the arms where they need it most, helping prevent costly failures and downtime.

Unless you are purchasing new trailing arms directly from us, this kit requires sending in your factory trailing arms for professional gusseting. Each set is welded in-house by experienced fabricators to ensure proper fitment, strength, and long-term reliability.

The gusseted trailing arms retain compatibility with stock mud flaps, keeping installation clean and OEM-friendly once reinstalled.
