SCS Gearbox 10-Spline Professional Series quick-change gears have been the proven leader in ultra-high performance quick-change gearing since 1987. They're made of 9310 aircraft alloy for maximum strength and are crown-shaved (ground before heat-treating) to minimize backlash and run out, broached for proper shaft fit, and black oxide finished. Gear sets #1 thru #30K are max lightened with the exception of #15K. The gears are lightened where possible, without sacrificing the strength for an average weight savings of 1 1/2 lbs.! The SCS Gearbox 10 spline Professional Series quick-change gears' extra five-step heat-treating process yields maximum gear life for high-stress applications such as Big Block Oswego Super Modifieds, World of Outlaw Sprint Cars, and IROC Series Cars.

Strange HD Pro aluminum case kits offer large bore sizes for the highest splined axles. They use superior 206-T4 heat-treated aluminum, which has 12 percent more yield strength and 32 percent higher tensile strength than the commonly used 356-T6; it's also substantially lighter than an iron case. HD Pro kits are designed for drag racing or abusive street/strip applications with high horsepower and torque. They feature a billet pinion support with 360 degree channel to maximize oil flow to the pinion bearing, as well as two contact points with the bore of the case--which holds the pinion shaft more securely for improved bearing and gear life. Their oversized tail bearing handles more load and greater rpm; billet main caps with chromoly studs support the carrier bearings, while significantly reducing ring gear deflection.
