Gears make a huge difference. I had 4.56's in my old truck and loved them

I need some gears myself. My 35's with 3:73's don't like pullin a trailer on a windy day

HAMMER!

Z71crawford - congrats on the gears, glad you like em! I have some stock 17's you can borrow anytime! Also driveshaft critical speed depends on the length of the shaft as well, and being 4x4 shafts are almost 2ft shorter you should be fine to 110ish mph! I've had mine up to 140mph a couple of times and no failures yet! Although I am upgrading mine to the full 5" 125wall aluminum shaft due to the spray!

Greensierra-what does you truck run on and of the gas? Also how do you like those irons?

HAMMER!

Dfw some gears bad. What brand did you go with?

GREENSIERRA

It is winter here so no track times yet, Our track opens in May and am really hoping to head to the track then.
I still have to put my new stall in and am expecting some great results from it
I absolutly love my Iroks, I had them in 39.5s and had to have them again when I was forced to make the truck smaller by the popo
what kind of times you ran?

HAMMER!
