The factory suspension is a compromise for many styles and built to a price point. If you want the classic looks of a 39mm narrowglide fork but want to pack some heat "under the hood," Race Tech Gold Valve and Spring kits from TC Bros. are the complete solution. Especially if you're rebuilding a fork with a set of our fork tubes, why not improve the internals?

Race Tech's cartridge emulator kits are the benchmark for keeping stock appearance but ratcheting up the performance. The heart of the kit is the spring; Race Tech offers several options to ensure you get the appropriate rate for your scenario and preferences.

The Gold Valves, known popularly as cartridge emulators, offer tunability that the factory suspension can't. Conventional damper rod forks offer primitive damping control that's not very dynamic; it's difficult to make this type of suspension perform well at both high and low cycling rates. Coupled with springs that are often inappropriate, it's no wonder that a stock 39mm fork leaves something to be desired performance-wise. Cartridge emulators are how you convert your damper rod setup behave like a modern upside-down suspension—the valving responds to the speed of the tubes during their stroke. 

Don't swap your fork. Make the narrowglide you have be all it can with internals from Race Tech!

Overall decent
Color: White, Size: King
It smelled a bit “chemically” for the first few days. The smell did fade and eventually go away entirely. It also still slides off of my bed despite having the straps to hold it in place. Otherwise, I have no complaints. It’s extremely comfortable and adds a few extra inches to the height of my bed.
