after lifting my truck and putting 35 inch rubbers under neith it the new tire size takes away power and screws up you're computer, speedometer and shift points. The superlift truspeed calibrater fixes all of that and costs $180. I was told that it takes four hours and costs $240 to put on. Yeah right...so i decided to put it on and got it all put together in an hour and a half! after it was installed i could really tell the difference it made, the power was alot better and felt the way it did with stock tires !

 

Where did you get it and do they have a web site? Thanks

 

i bought it from my friends local offroad shop but you can buy them from magazines, superlift, 4 wheel parts, and probably any other off road shops! yeah if you go to www.superlift.com i think they got it on there along with some info!
