High-Performance Helical Gear Limited Slip Differential with Quiet Operation

Eaton's Detroit TrueTrac Limited Slip Differentials have long been one of the top-dogs when it comes to performance drivetrain upgrades, and adding one these bad boys to your 1997 to 2020 F150's rear end will enable your aggressive truck build to claw its way out of just about everything while maintaining OE on-road drivability all without costing an arm and a leg like a full locking differential. The Detroit TrueTrac Limited Slip Differential features a Helical Gear-style internal design with helical-cut gears instead of clutch packs, which allows for much greater longevity and reliability in performance applications than LSD systems that use more standard clutch packs. The TrueTrac has smooth, quiet operation, and they only way you'll know if it's engaged is when your truck suddenly has more traction.

Automatic Engagement with a Maintenance-Free Design

Eaton carefully designed and constructed their Detroit TrueTrac limited slip differential to handle just about any application you have in mind. The TrueTrac has precision-cut helical gears and pinions housed inside a high-strength flanged body with covers that all comes pre-assembled and ready to drop into your truck's rear axle. The TrueTrac has no wearable parts and requires no maintenance other than standard differential fluid changes. The differential automatically and smoothly engages when a wheel experiences traction loss. During normal driving, the TrueTrac operates like a standard open differential to keep your street drive smooth and noise-free. The TrueTrac is designed to drop right into place of the stock differential on 1997-2020 F150s with 9.75" rear ends and 34-spline axles.

1997-2020 F150s only: this differential only fits Ford 9.75" rear ends with 34-spline axles, like those found on 1997 to 2020 F150s.

Will not fit SVT Raptors: this locker will not fit SVT Raptors, due to the fact that Raptors have 35-spline axles.
