SCS Gearbox 6-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 #32 are max lightened where possible, without sacrificing the strength for an average weight savings of 1 1/2 lbs.! The SCS Gearbox 6 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.

Powertrax Grip Pro traction systems are the latest design in differential technology. They combine the smooth operation of a limited-slip differential, with the strength of a fully machined, forged steel case. Using 3x2 spiral gear engineering, the Powertrax Grip Pro delivers progressive and variable traction. Based on throttle input, you are in control of how much traction is applied. These differential systems are great for use where finesse is just as important as brutal traction. On the road or track, in the rain or snow, Grip Pro is a winner! The systems come fully assembled and there are no friction plates—so you can use any gear oil you like, including full synthetic and racing lube.

Strange Lightweight Pro Race spools give you the traction that you need by locking the axle shafts together, forcing your rear tires to turn at the same speed. They're CNC-machined from forged chromoly steel to provide a more rigid ring gear mounting. This eliminates the gear failure caused by case deflection or differential side-gear failure. For even lighter weight, there are aluminum-alloy versions available for some applications.

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.
