[quote=Grigg]What are you trying to do?
I ask because the slow gears in the rear axle might be the biggest problem (usually are) and throwing transmissions at it won't make enough difference. Swapping rear axle and possibly transmission too might be the answer... depending on your goals.

im just trying to make this thing into a weekend driver.no heavy loads. so the nv4500 and my stock axle gearing would be a good mix?
