I am trying to decide which gears to to install in my 99 cc psd it currently has 3.73's and I was wanting to here from some one that has already installed 4.56's or 4.10's that is running 35" tall tires what they think about this set up. Thanks in advance for sharing your experience.

 

what did you want to know? I have 4:10 gears and am running 36" TSL Radials, also my buddy has 4:56 with 36" TSL radials

 

Did you change both front and back gears. What did it cost you to have the gear changed out? Is there a huge difference in fuel mileage?

 

I changed front end gears, the rear was allready set up. There was a slight loss in milage. I only had to buy a new rack and pinion. It was around 250 if i remember correctly. With the 4:56 i was told that you need a differnet ??????(i can't think of what its called) It's what the rack bolts on to, with the spider gears in it?

 

If you want it to pull like it did stock, then 4.30 gearsets (yes, you have to do both ends) will get your final drive ratio very close to what it was with the stock 3.73's and 31" tires

 

Thanks for the info. I do quite a bit of towing on the weekends and drive in town all week long. I want this truck to tow like a champ but don't want to sacrifice fuel mileage.
