The BMW E39 540I Differential is a state-of-the-art helical gear differentials designed, developed, and manufactured in the USA by AutoTech Driveline. 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. .
Torque ring gear bolts to 85ft lbs
- Unlike other gear driven diffs, when unloading a wheel, only the Wavetrac will still put power to the other wheel
- Lifetime warranty (even transferrable), made in USA
- Works on acceleration and deceleration (most if not all other gear driven diffs only operate on acceleration)
- Non-intrusive, won’t be ‘fighting the steering wheel’ in low speeds/tight turns compared to a spool/clutch type diffs
- Maintenance free, no parts to replace or oil to constantly change
- Super durable (beefed up gear/housing interface, billet steel housings, 9310 alloy steel internal gears)
- Direct replacement for factory diff
- ARP fasteners
- Constantly biases power to drive wheels seamlessly in between acceleration and deceleration, and with no delay
- Smaller gear package to reduce mass, yet higher tooth strength to increase durability
- Innovative wave design of preload hubs/gear interface means will work in zero load or near-zero load conditions (unlike Torsen or other gear driven diffs)
- Works with existing traction control/ABS electronic systems seamlessly
