XL Rear Shock Boots for 137mm Shocks are protective sleeves that shield the rear shock shaft from dirt and debris while preserving full suspension travel. The captured design helps prevent tearing and offers durable, long-lasting protection without compromising performance.

Designed to fit 137mm rear shocks, these boots come in multiple lengths to match different shock sizes. They should be installed before attaching the shock rod end to the shaft and require compatible locking spring perches and rod ends to secure properly. The boots keep dirt out and maintain smooth suspension action by staying clear of the spring perch and rod end during installation.
