Split Ring Collar - RockShox

The Fluid Focus Split Ring Collar for RockShox coil rear shocks is a precision preload collar upgrade designed to keep spring preload exactly where it’s set—reducing the chance of the collar backing off during hard riding and repeated impacts. Its split-ring design creates a positive mechanical clamp on the shock body, delivering more consistent setup retention than typical stock-style collars, even when running very light or zero preload for maximum sensitivity.

• Secure spring preload retention - Helps prevent the gradual loosening that can occur with stock collars, keeping sag and ride feel more consistent ride to ride
• Split-ring mechanical clamp - Clamps firmly in place instead of relying on friction alone, improving stability with minimal or zero preload settings
• RockShox-specific installation - Can be installed without rear shock disassembly, reducing service time and complexity
• Coil shock setup control - Supports precise preload adjustment for riders dialing in traction, support, and small-bump compliance
