Differential by Wavetrac®. Dominate the track or hit the trails with confidence by fine tuning your vehicle for neck-breaking speed and performance with this premium differential component that delivers the ultimate in high strength and toughness. This rock-solid part is designed to provide the gearing that helps ensure your engine stays in the powerband for faster acceleration while providing maximum safety during tough driving conditions. Wavetrac® diffs are state-of-the-art helical gear differentials designed, developed, and manufactured in the USA. The Wavetrac® Differential is the only torque biasing differential on the market with patented technology that mitigates wheelspin when an unloaded wheel condition arises. During zero axle load conditions, the Wavetrac cam device acts to create internal load, maintaining drive on the gripping wheel instead of acting like an open diff (and going nowhere!). Super strong 9310 alloy steel gears are enclosed in case-hardened steel bodies, held together with ARP® fasteners. All Wavetrac® differentials include a transferable, Limited Lifetime Warranty.
