Well my truck is a dog at the track won't 60ft to save its life. Has the stock 3.42s with stock posi, on 275/55/ R 20 tires. What brand posi should I look at? An im thinking 3.90 gears, thoughts on that? Truck is my dd with 50/50 highway an city driving , so don't want to gear it to high. Truck in sig thoughts? Thanks.

 

Anyone?

 

Don't think they make 3.90 for your front end. Which leaves you with 3.73s -Not enough change to swap. Or 4.10s, which may be too much.

 

I don't think 4.10's would be too much at all they came factory in a lot of vehicles. Plus the tire you are using is pretty tall. The tires are actually hurting you a lot. You really should get a trutrac. And some traction bars. What is your 60' time. I am usually right around 1.85 with 275/55/20's, and 3.73's and no traction bars. Next year I will be on a little lower profile tire, 4.56's, and plan on doing something (not 100% sure yet) for traction bars/long bars.

 

My 60ft was a 2.4 getting on it pretty hard but not all the way due to spinning that was with no stalling it up. Fastest time was 15.35 at 93.85 mph. It won't stall much tho it just blows the tires off. It should run alot faster then 15 its really driving me crazy. I've been looking at the assassin bars, didn't know for sure if they would help that much tho. I'm new to the suspension helps you go fast thing lol

 

I run 4.10s with 255/70/16 like 29.5-29.8 tall runs 2100ish at 70mph so I would do 4.10s if I where u with the bigger tire then me

 

Ltr, whats your mpgs like?

 

Thoughts on my setup an what would help

 

4:10's and launch it in 4wd.

 

How will 4.10s do with mixed driving? Its my dd so mpgs matter some
