Race Tech Type 1 Gold Valve Combo Kit - FMGV 2823C

Combo Kits are the best valving choice as they include both a Compression as well as a Rebound / Mid-valve Gold Valve Kits.
Some people choose to do just the Compression Gold Valve Kit however the Rebound Gold Valve works very closely with the Compression to create the optimum damping curve.
The Combo Kit is discounted over buying both kits separately. On SFF Forks it is the only choice.
