I just bought a 3.73 gear for my 2.73 posi unit. I need to order a install kit, but dont know what I should get.

Jegs has a kit for around 20 bucks, but does not have the ring gear bolts or pinion nut.

Summit has a kit for about 45 bucks. It has the ring gear bolts, and pinion nut.

Is it necessary to replace the bolts and pinion nut or just the smart thing to do for extra precaution. I dont want to ruien my new gear or my posi unitl.

thanks.

 

I got mine from Summit, I forget the brand, but it was $99.

 

I just ordered the "complete kit" from Thunder Racing. They have three different kits to choose from ranging form $50-$130. You should compare these kits to the ones that summit and Jegs offer then make your decision.

 

so when you buy gears adn expect to put them in, best bet is to get an install kit to change out the old crap??? Damnit taht is more moeny i ahve to spend.

 

Yeah, you have to buy an install kit.
