question about running 37's
if i am going to get the rize 8 inch kit and run 37's on my truck (a 2008 f150 4x4) i would think i would need to re-gear. but i think that is alot of money. is there other ways around that. like i have heard about the edge evo tuner, would that solve the problem without having to re-gear. thanks for your help guys.

no, there is NO way around regearing. w/ 37'' tires, you will eventually blow the transmission. if you then proceed to rebuild it w/o regearing, you will be on your way to blowing it again. i speak from knowledge backed by the personal experiences of friends of mine. an edge tuner isn't worth a sh*t for one, and for two, computer adjustments cannot be made to compensate for the realized increase in your gear ratio due to the oversize tires.
also, a rebuild is ~$2000 on an automatic transmission. that is still more expensive than regearing.

$1500 is about average, and you going to need a new carrier in the rear if you go with the 4.88's I believe, so, perfect chance to get an upgrade with either a clutchless LS, or a locker. So, your probably looking at closer to $2,000
Definately go with 4.88's .

Remember to tell em your front gears are 8.8" IFS axle with Reverse cut gears.

Yes, 4.88s are going to be needed. This is coming from a guy that tried to get by with 3.73s and 37s. The 4.88s will help save your transmission. It takes a lot of the load off of it. Also, don't waste your money with the Edge. I'd go with a custom tuned Xcal2 from VMPTuning.com. I also bought the Edge and had numerous problems with the tuning. My torque convertor would violently lock and unlock around 65-72 mph, it was horrible as well as other things.

Like minimonster said. The truck was a slug, it shifted sloppy, it was only a matter of time before something gave out. Got to remember that's a whole lot of rotational mass compared to a stock tire and wheel.

yea it is. a lot of lift shops have told me you dont have to re-gear. but then i have had some that have told me you do have to. i guess that shows the quality of the shop haha
