Showa 14mm Damping Rods

 
This is what a worn out rod looks like (below).
 
2017 through current Showa forks with 14mm Damping Rods have been wearing through the stock coating causing internal cartridge seal leak failures. These are hi-quality replacements with much improved coating.

Fork Spring Conversion System

 

The Race Tech Spring Conversion System (SCS) transforms air spring forks to a coil spring.

Most riders prefer the feel of a coil spring over an air spring. These kits are designed to transform your air forks into an SFF (single function fork) style coil spring fork. 

For the ultimate in performance select a complete Gold Valve Kit and install it using Ultra Slick USF-05 Suspension Fluid.

Springs sold separately. Be sure to select the proper rate RT Hi-Performance Spring for your Spring Conversion. See the ►Product Search for applications, spring and rate recommendations...

Spring Conversion Stealth Kits
WP 48mm AER Forks
AMA Stock Class Legal!

Stock Cap shown. Spring sold separately.

 RT Fork Spring Conversions have been improving ride quality for all the Air Forks for years now. The only problem is they can't be used in the Stock AMA Classes because it looks different externally.

This Fork Spring Conversion solves that problem for WP 48mm AER Forks. It makes it legal with an adapter that uses the stock cap so they look original from the outside.

19mm SHOCK SHAFT KITS FOR SX/AX/FMX/Flat Track

The stock 16mm shock shafts found on most modern stock shocks are at risk of bending under the extreme circumstances of modern Supercross, Arenacross and Freestyle competition. Thus the Race Tech Pro Series 19mm Shock Shaft Kit was born, and ultra-durable shock shaft to withstand the rigors of Supercross and Freestyle. The RT Shaft Kit is 40% stronger than stock shafts!

The RT Pro Series Shock Shaft Kits also include a built in Rebound Separator, and a spring top-out (instead of the stock hydraulic setup for KYB units). This provides better initial movement, better grip and better firmness.

Flat Track riders particularly benefit for a much wider adjustment range to deal with the changing track conditions during the day and around the country.

FORK COMPRESSION POSTS FOR SX/AX/FMX

BOTTOM-OUT BUMPERS
 

Bottom-Out Bumpers are an often overlooked part of shock maintenance. Original equipment bumpers start breaking down immediately.

They are typically effective over 25 to 33% of the suspension travel and, particularly on dirt bikes, can make a huge difference between a plush landing and one that's not so plush.
