Split Ring Collar - Fox

Fluid Focus Split Ring Collar - Fox replaces a stock coil shock preload collar with a true split-ring clamp for more reliable spring preload on Fox/Marzocchi coil rear shocks. By mechanically clamping in place, it helps prevent the common “backing off” that can change ride height and suspension feel over time—especially for riders running minimal preload for sensitivity.

• Split-ring mechanical clamp - Locks preload securely to reduce loosening from vibration and repeated impacts
• Consistent spring preload - Helps maintain sag and ride height once the shock is set up
• Stable with low or zero preload - Designed to stay put even when only light preload is required for proper spring fit
• Fox/Marzocchi-specific installation - Must be installed while the upper eyelet is unthreaded from the damper body; plan installation accordingly
