Yamaha SHO Supercharger Bearing Rebuild Kit
R&D SHO | FZR Supercharger Bearing Rebuild Kit
Our Price: $42.95

R&D's new High Performance Billet Supercharger Shaft eliminates the weak design features of the OEM and aftermarket HKS supercharger shaft. After analyzing the OEM HKS shaft design and sorting through the various failures we had with it while testing our popular Monster S/C Wheels, we developed a superior shaft design. The new R&D shaft is not a copy of the fragile HKS design. Rather, it is a completely new design, superior in material strength and improved in every way.

H.P. Racing Billet Shaft Kit
R&D Ultimate Billet Supercharger Shaft Kit - Yamaha SHO
Our Price: $351.95

R&D's new High Performance Billet Supercharger Shaft eliminates the weak design features of the OEM and aftermarket HKS supercharger shafts. After analyzing the OEM HKS shaft design and sorting through the various failures we experienced with it while testing our popular Monster S/C Wheels, we developed a superior shaft design.

The new R&D shaft is not a copy of the fragile HKS design. Rather, it is a completely new design, superior in material strength and improved in every way.

The new R&D Shaft is precision CNC machined, heat treated, and precision ground from billet steel alloy. Featuring a uni-structure design that incorporates the shaft and gear as one billet piece, much like a transmission shaft. This eliminates the fracture point on the OEM design where the pressed on gear shears off the end of the shaft. The new one piece design will also eliminate gear slippage under high boost loads and increased heat.

Next, we increased the inadequate 6mm thread diameter on the OEM shaft to utilize a larger well proven “Turbo spec”. The added strength of the new 5/16-24 left handed shaft thread will not fatigue or break under extreme conditions. The larger thread diameter will also allow wheel torque specs to be increased safely.

The undercut or “fracture point” where the shaft meets the shoulder on the OEM design was also eliminated. Replaced with a strong fillet radius and mating Thrust Plate. The new kit supplied Thrust Plate features a matching shaft fillet radius and is designed to eliminate potential metal galling with higher boost.

Lastly, the Ultimate Shaft is 17% lighter than all other shafts on the market. The reduced reciprocating will extend supercharger clutch life. The R&D Ultimate Supercharger shaft design is the lightest and strongest on the market.

Used by Chris MacClugage to win the 09’ APBA Pro Open Runabout National Championship. Kit comes complete with Billet Shaft, new Thrust Plate Washer, larger nut and installation instructions. All in all, the new R&D Ultimate Billet Shaft is not just a replacement shaft, but a solution to end all supercharger shaft problems.
RIVA FX-SHO Supercharger Shaft
RIVA FX-SHO/FZR/FZS Heavy-duty Supercharger Shaft Upgrade Kit - GEN 3
Our Price: $494.95

RIVA "GEN-3" SHO / FZ Heavy Duty Supercharger Shaft Upgrade Kit 
 
Our Super-Duty ‘GEN-3’ Supercharger Shaft Kit provides the ultimate in reliability for high boost applications. Kit features a revolutionary hydraulic shaft stabilization bearing that limits shaft deflection and wear. Bearing stabilizes end of supercharger shaft via high pressure oil film dramatically increasing the stability of the system. Hydraulic end bearing and one-piece shaft bearing are fed by a through-shaft oiling system providing superior lubrication. Oil is delivered by braided stainless line and injected into a billet end cap that houses hydraulic bearing. Shaft is precision machined from a single piece of high-strength billet steel producing shaft, collar & gear as one piece. This eliminates the common failure point on stock shafts where OEM gear is pressed onto shaft. Shaft also features larger diameter threads & nut for added strength. Kit includes new one piece bearing with increased surface area providing improved torsional stability of shaft. Bearing features superior materials & finish treatment for reduced friction & abrasion resistance. This Shaft & Bearing Kit is a direct replacement for OEM parts and requires no additional modifications for use.

Key Features Include:

  • Hydraulic end bearing minimizes shaft deflection.
  • Through-shaft oiling system maximizes lubrication.
  • Braided stainless steel oil line delivers additional lubrication.
  • One piece shaft/collar/gear construction. Stronger billet material & superior surface finish.
  • Larger diameter threads & nut.
  • One-piece bearing improves shaft stability.
  • Bolt-on installation (no machining required).
  • Manufactured exclusively for RIVA Racing by HKS.
