i just put a few mods on my truck (intake, chip, and exhaust) but i know them lb7 5sp allisons arent gonna last very long on the 120hp setting, and at the moment i dont have the money to put a stage 4 tranny in like i would like to sometime later on, would a shift kit be my answer on trying to save my tranny for a little longer?

 

It will help some and should help ya get by until you have the cash depending on your driving habits and style.

 

Even with that shift kit be very careful. It's very easy to limp a stock 5 speed on a +75hp tune.

 

I went to school to rebuild the Allison and the 5 speeds get little to no benefit from a shift kit. Save your money and build it up right.

Till then go easy on it.
