Well got the 4.56s installed Tuesday and by the time Sunday was here i put 450 miles on them! Went to the my tuner to get the spedo correct and a 93 octane tune, as he was setting everything up for the tune he told me to gun it! At first i told him NO that i still have 50 more miles to go, he then insured me that 50 miles wasn't going to do anything for the truck so i took his advice. I slowed down to hit it from a dig and damn was i impressed! My cousin in the back was just as surprised as me due to the fact that it actually started to roast the tire when it was punched! Now keep in mind with the 3.73 it would barley chirp them, now it'll burn them. I think the 4.56s had to be the best mod Ive ever done! It goes through the gears really quick use to shift out of 1st at 55 now shifts out around 40. Cant wait to do some towing and a little mud riding now!

I almost went 4.56 on the last truck and then sold it. I should have kept it. Sounds like fun

I had 3.42s,3.73,4.10 then 4.56s each step I went up I loved more and more. Was about to get 4.88s but ended up selling the truck

I love my 4.56s as well, I was actually surprised at the mid and top end gain from them, figured it would be all low end.

gears are amazing!!!
I would love to throw a set of old stockers and see what I could do. I can roast mine all through first and half way through second from a stop or roll

I have been tempted to throw on my 26" track tires and see how they feel, and then put on my stock size tires and see what they are like. I know they burn the 32" tires I am currently running, the stock 29" tires wont have a chance.LOL

BLUES MAN

I love my 456's. Used to have 22's and it would smoke them. Now im on aluminum 17's.... Ya i need new rear tires LOL

I'm very tempted to get stocks now! Anyone have any I can borrow ??
With the new gears do I have to worry about a certain speed? I know the drive shaft gets dangerous at 105 on stock gears and tires.
