RockShox Metric Shock Coil Spring

Spring rate selection is highly personal and depends on your rider weight, bike leverage ratio, and preferred sag. A 350 lb spring is generally suited for lighter riders or bikes with specific suspension kinematics; we recommend using a suspension calculator or consulting your bike's manual to confirm your ideal spring rate before purchasing.

This spring is designed for metric shocks with a 114 mm length and 37.5-45 mm travel range. Always verify your shock's stroke length and eye-to-eye measurement to ensure compatibility, as metric sizing varies significantly across different shock models.

Coil springs offer a linear feel that many riders prefer for its consistent, supple performance throughout the entire travel range. Unlike air springs, they are less affected by temperature changes and friction, providing a predictable, 'planted' ride quality on technical terrain.

Steel coils are relatively low-maintenance, but you should periodically inspect the spring for any signs of wear, corrosion, or deformation. Ensure the spring is properly seated on your shock's spring retainers and keep the area clean to prevent debris from causing noise or damage.

While this spring is engineered for RockShox metric shocks, it may fit other brands if the inner diameter and length specifications align perfectly. However, we strongly recommend sticking to the manufacturer's specified components to ensure the spring fits securely and functions safely within your shock's housing.
