Suspension

The first step to great handling is selecting proper spring rates front and rear. With over 900 Hi-Performance Spring designs, Race Tech is almost guaranteed to have what you need.

Through years of testing and manufacturing experience, Race Tech has developed a full line of Hi-Performance Springs using the finest materials and processes. RT Springs have the highest stiffness-to-mass ratio in the industry; making them extremely light weight for their particular rate.

RT Hi-Performance Spring Features

• Extremely accurate rates
• The tightest tolerances in the industry
• Heat-treated and Shot-peened
• Preset to eliminate sacking-out
• Extremely lightweight
• Made in the USA

Race Tech's award winning Gold Valve Kits for Forks and Shocks provide a personalized setup. Gold Valves have an improved flow design that dramatically reduces harshness while actually increasing bottoming resistance (as shown with data acquisition). These Kits can be installed by individuals interested in understanding and tuning their own suspension or they can be installed by a Race Tech Center or Race Tech's Service Department. The Kits include Valving Shims and DVS Custom Setup Sheet for the individual rider and conditions.

Fork Rebound Gold Valve Kit: Many stock rebound valving systems are grossly inadequate. No matter what modifications are attempted, the stock valves will never perform with precision or control. If you race or simply want the best, Race Tech's Rebound Gold Valves are the solution to improved traction. Used by major factory teams, these valves increase flow area, putting valving control on the shim stack instead of the piston. This results in outstanding tuneability, improved control and traction.

G3-LD Shock Gold Valve Kit: Guaranteed to provide better handling and each kit includes a Gold Valve and a personalized valving setup. You may install the kit yourself, send it to Race Tech, or send to your local Race Tech Center for installation. The G3-LD Gold Valve design creates better flow allowing improved bottoming resistance, plushness, control and traction as well as increased tuneability.

Benefits of Gold Valves:

• Reduced harshness
• Increased bottoming resistance
• Improved traction
• Consistent feel
• Increased tuneability
• Personalized setup
• Technical support
• 100% Guaranteed
• Made in the USA

Race Tech's award winning Gold Valve Emulator Kits for Damping Rod Forks provide the compression damping curve of a well tuned cartridge fork. Gold Valves Emulators improve oil flow dramatically reducing harshness while actually increasing bottoming resistance.

In most cases these kits can be installed by individuals interested in tuning their own suspension. They can also be installed by a Race Tech Center, Dealer or, of course, Race Tech's Service Department. Emulators allow for easy adjustability too.

The Race Tech Spring Conversion System (SCS) transforms your air spring forks found on Kawasaki KX450, Suzuki RMZ450, Honda CRF250 and KTM/Husqvarna WP AER 48 to a coil spring setup.
Most riders prefer the feel of a coil spring over an air spring. The RT SCS is a set it and forget it solution. These kits are designed to transform your air forks into an SFF (single function fork) style coil spring fork. Be sure to select the proper rate RT Hi-Performance Spring (sold separately) to compliment your RT Spring Conversion System. Installation is so easy you'll be ready to hit the track within minutes with this "drop-in." No need to check pressures before each ride any longer. Springs - Sold separately. In general 48mm forks require FRSP 4466 Series Springs. 49mm forks require FRSP 4566 Series Springs. FSCS Series Spring Conversions

These 17-4 Stainless Steel Compression Posts replace the stock aluminum units. The stock units are at risk of bending with the extremely agressive 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.

See Reservoir Rod Compression Posts in the Twin-Chamber section of the Product Search FPTC CR Series.

Dual-Chamber Pressure Springs are there to prevent cavitation. Pressure spring-rates need to match stiffer valving used for Supercross and outdoor motocross conditions. Proper rate Pressure Springs provide a consistent feel and smoother cornering. RT Pressure Springs fit both Showa and KYB.

Coatings can drastically reduce friction to provide a smooth and consistent feel, as well as provide excellent resistance to wear.

DLC2 is the best of the best when it comes to coatings. Applied to the exterior of the chrome tubes, it is extremely hard and slippery.

DLC2 Coating Benefits

- Excellent resistance to wear

- Extremely hard and slippery surface

- Creates "factory" look

Fork Tube & Shock Body Hard Anodizing

Hard anodizing is a treatment for aluminum surfaces only. Many of today's stock forks come with the aluminum outer tubes hard anodized from the factory; however, the coating is many times very thin - wearing through in less than 10 hours of riding. Once worn, bushings ride on soft aluminum creating friction and an inconsistent feel.

Hard Anodizing Benefits

• Excellent resistance to wear
• Hardness provides reduced friction
• Allows exterior surface color option

Rebound Separator Valves replace the Shock Shaft Nut and with an asymmetric valve that flows through the Low-Speed Rebound Adjuster. This means Low-Speed Rebound Damping can be set for excellent traction while keeping the Compression nice and firm. This dramatically increases traction while giving better bottoming resistance.

RT Reservoir Caps are anodized billet aluminum and comes with a recessed (protected) Schrader Valve or, as in the case of the YZ450, a sealed Nitrogen Needle port. Many of these caps provide more nitrogen volume and are easy to service.

RT Bladder Conversions replace the stock reservoir piston with a bladder. Found on many aftermarket shocks including WP. These kits make servicing the shock easier as well as improving small bump harshness.

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 a more free initial movement for less harshness.

Whether you ride a modern bike or vintage, we can build G3-S Custom Shocks that will out-perform your highest expectations. Guaranteed!
