Eaton’s Mobility Group is rolling out two new aftermarket differentials for diesel-powered GM trucks and Jeep off-road builds, designed to deliver serious traction upgrades. The new Detroit Truetrac 31-spline differential fits GM’s 11.5-inch rear axle on 2020+ 2500HD Silverado and Sierra models, bringing extra stability and grip for heavy-duty towing or demanding terrain. For Jeep fans, the 35-spline ELocker offers enhanced durability and torque control, a perfect match for 2018 and older Jeep models with Dana 44 axles, including Wrangler JK, TJ, LJ, and CJ variants.
These new differentials will debut at SEMA 2024, giving enthusiasts a first look at Eaton’s latest innovations. The Detroit Truetrac delivers smooth, automatic, limited-slip functionality using helical gears, staying out of the way during normal driving but seamlessly locking up when the traction challenge ramps up. For those looking for on-the-fly control, the ELocker shifts from open to fully locked with a dash switch, ensuring drivers get instant grip for tough climbs and technical obstacles.
Backed by years of refining their differential portfolio, Eaton’s new additions showcase the brand’s commitment to performance-driven upgrades for popular North American vehicles. Both units will be available from Eaton’s U.S. distribution centers starting late Q1 2025, ready to elevate traction and durability for work and adventure alike.
