I really like this design and you can get the clearance just right easily

And so should fit a range of F150 models (late 80's early 90's) with the dana44 with reverse gearing on the ford independent front suspension (IFS).Note - unlike the rear ford 8.8 these go on the inside of the bearings, so buy 2 sets of carrier bearings and make one a setup bearing set. Although a little more expensive, this actually works better/easier then the 8.8 setup IMO to get the lash just right.

Much needed for DIY gear installersSaves a lot of headache while re-gearing

Expensive but the size and options work perfect when you replace the carrier all the option neede

Replaces the crush sleeve, allowing precise, repeatable, adjustment of pinion depth and bearing preload.

Nice set up.

Able to get pinion preload much closer to spec than with a standard crush collar.

Great product
