Tried and Tested in Extreme Off-Road Use

No matter how optioned out your F250 or F350 Super Duty comes from the factory, nothing beats the insane on and off-road traction you get from the Powertrax Lock Right 35-Spline Differential Locker for 10.25" rear-ends. These automatic lockers replace the spider gears in your stock differential carrier without affecting your ring and pinion settings, giving you the straight-line performance of a solid spool axle with the traction needed for spontaneous turns and cornering.

Does Not Require Replacing Your Differential Case

The Powertrax Lock Right Differential Locker installs easily, doesn't alter ring and pinion setup, and doesn't require replacement of your differential case. Powertrax's strongest locking differential comes backed by a 2-year, 100,000-mile warranty for confidence and peace of mind whether on the street or off the pavement.
