Fox 2" Spring Perch Adapter For Using A 3" Spring On A Shock That Would Normally Use A 2-1/2" Spring

This aluminum adapter ring sits on top of your existing bottom spring perch, on either side of your spring divider, or below your existing top spring preload nut. Usually when customers purchase this adapter, they're running a single 3" inside diameter spring or if they're doing a dual rate coil setup, they'll run a 2-1/2" inside diameter upper spring and a 3" diameter lower spring.

This adapter works great on a 2" x 16" stroke coil over shock. 16" stroke shocks use a 16" upper spring and 18" lower spring. 16" springs with a 2-1/2" ID are common but 18" springs with a 2-1/2" ID aren't common. There are a lot of 18" springs with a 3" ID to choose from instead.

Use with:
• 980-02-057 = 2" x 16" emulsion coil over shock
• 981-20-113 = 2" x 16" emulsion coil over shock


• 980-02-059 = 2" x 16" hose remote reservoir coil over shock
• 981-20-123 = 2" x 16" hose remote reservoir coil over shock


• 980-02-160 = 2" x 16" piggyback remote reservoir coil over shock
• 981-20-118 = 2" x 16" piggyback remote reservoir coil over shock

This adapter adds 0.410" to the height of your spring per plate. Make sure you have enough room to fit the height of the spring plus 0.820" (roughly 13/16" for two plates) on your shock.
