About this item

If you've got a Dodge Ram 2500 or 3500 with the NV4500 5-speed transmission and 4WD, this little part can save you from a big headache. The stock 5th gear lock nut has a habit of backing off, which can wreck your transmission. This retainer locks it in place with a 4-tooth design that fully engages the nut and a 29-spline body that matches the main shaft.

It's a simple but effective fix that prevents failure and keeps your gearbox solid. Just make sure your truck has the 29-spline output shaft (most Dodge 4WD NV4500s do). It won't fit GM/Chevy versions, so double-check your model.

Easy to install during a transmission service or repair. Whether you're towing heavy or just daily driving, this retainer adds peace of mind. Don't let a loose nut leave you stranded—upgrade to a secure solution.
