The new generation Riva R3 Supercharger Impeller and Riva Super-Duty Gen-4 Supercharger Shaft Upgrade kit will take your SVHO to the next level!
The package delivers incredible horsepower and torque throughout the RPM range. All new blade design produces increased boost pressure and air flow resulting in excellent acceleration and top speed. Precision machined from billet aluminum to exact tolerances and anodized to prevent corrosion. Installs quickly and easily into stock supercharger housing. Includes detailed installation instructions.
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.
