Damping Rod style forks are notorious for being too harsh, too mushy and too easy to bottom. Gold Valve Cartridge Emulators remedy this problem by controlling the compression damping with a tuneable valve. The Emulator sits on top of the damping rod and is held in place by the main spring.
Simply put; Emulators make damping rod forks perform like well-tuned cartridge forks. Installation and tuning for any condition or rider preference is very straight-forward.
Simple to install and completely tunable for all conditions and rider preferences.
An excellent replacement for the stock fork boots. These are great for protection from dirt, rocks and other contaminants. These boots utilize the latest advances in material technology to adapt to fork and styling demands. These high quality fork boots are 1/4 the price of the OEM factory replacements.

Based on the wildly popular Race Tech Suspension Seminars taught by Paul Thede around the world, this step-by-step guide shows riders how to make their bikes handle like the pros. Thede gives the lowdown on all types of suspension, including cartridge and non-cartridge forks as well as dual-chamber and nitrogen-charged shocks.
The three forces of suspension, testing procedures, even the black arts of chassis geometry: This explains it all. The book provides step-by-step photos of suspension disassembly and assembly as well as a detailed troubleshooting guide for dirt, street and track.
Showa removed the schrader valve on many newer rear shocks. Now you need a needle to recharge your shock with nitrogen after a rebuild. Race Tech built this unit just for that job.
The features of this tool include 300 psi capacity, bleeder valve and T-handle plunger pin chuck. Swivel chuck has a 12" flexible hose. Comes complete with instructions, carrying box and Schrader valve extension (required on some Showa shocks). Nitrogen bottles available at any welding supply house.
