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.

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 was they couldn't be used in the Stock AMA Classes because they looked 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. FSCS WC38050915 – Add to cart Stealth Retro Kit 
For those that already have our Fork Spring Conversion Kit for WP 48 AER Forks. This converts to a Stealth Kit with the use of the stock cap. FSCS CK3805010 – Add to cart |

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. ►Product Search for applications. | FORK COMPRESSION POSTS FOR SX/AX/FMX 
These 17-4 Stainless Steel Compression Posts replace the stock aluminum units. The stock units can bend with the extremely stiff setups required for modern Supercross, Arenacross, and Freestyle competition. These units are FOUR TIMES STRONGER than the stock posts and are a must for Supercross, Arenacross, and Freestyle Motocross. ►Product Search for applications. |

SPACERS 
Install internally on the shock shaft to lower the bike up to 4 inches. Not recommended for shocks with top-out springs. Each kit includes a combination of 2 and 3mm thick spacers so you can lower in 1mm increments. | 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. ►List of Bottom-out Bumpers with dimensions Look your bike up in ►Product Search for proper application. |
