High-Performance Helical Gear Limited Slip Differential with Quiet Operation

Eaton's Detroit TrueTrac Limited Slip Differential has earned its place as a preferred performance drivetrain upgrade, and adding one these bad boys to your 1985-2007 F250 or F350'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.

Fitment: This Eaton TrueTrac locker fits 10.25 and 10.5" standard (rear) axles with 35 spline axle shafts.
