ok i am about to install some 4.56's on my 2000 jeep tj 4" lift 33" bfgs is that too low of a gear or is it about right? i talked to the guys at 4 wheel parts and they said it was about right are they just trying to make a sale or what? and how much should they charge me for install? thanks for the great advice i know yall will give me. I don't wheel too hard but i want to be able to run in fith gear going down the highway, i talked to a guy with some 4.56's and he said he hauled going up and down vail pass in colorado which is where i'll be in a couple of years, i forgot to ask what kinda milage he got.

That R&P gear set will be fine. What engine do you have and what are you wanting to get out of your Jeep with new gears and overall?

the 456 with 33's bring it pretty close to stock. i want nothing more from mine. i have a superlift tru speed box to get the speedo right, and i'd probably research the plastic speedo gear more if i were doing that again although the box i have works ok. i get between 14 and 18 mpg, but that's pretty standard.

That's the ratio you want. You might want to compare prices on set-up and install. Call Sunray Engineering in Weatherford also, they do great work. See who will give you the best deal and who can get it done in the time frame you want.
