When I purchased my truck from a guy who had lifted my truck with blocks in the rear and a 2.5 leveling kit in the front, he was running 35inch tires. Well its time for new tires. I want to remove the back block lift and go back with 33 inch tires. and possibly change the leveling kit if it does what he said which makes the truck to high in the front. The problem I have is what u bolts and components I need to do this. Is there a place i can put in my vin and find out which set of U bolts and components I need to go back stock, because there is basically like 3 options for U bolts depends on the rear end. Also is there a stock block, from everything i have seen there is not one. but there is a top plate for the U bolts, did this left on there use that same stock bolts.

Maybe someone can point me in right direction, I have went the dealer route and that want outrageous price for some U bolts.

If you jack the rear wheels up on your truck, you can make a mark on the drive shaft, then turn a rear tire one revolution while counting the revolutions of the drive shaft. For instance, if one turn of the tire rotated the drive shaft 3.4 turns your truck has a 3.42 axle, or if it turned 3.75 turns you truck has a 3.73 ratio axle. Once you have figured out which axle your truck has you can go to rockauto.com and find the correct suspension parts.

You do know that after you change your truck back to the original diameter tires you speedo will read incorrectly? Well, that is if it was recalibrated to the larger tires.

Thank you. My speedO is still reading stock. I use my edge to know the correct speed. If it says I am running 60mph at this time. I am running 70. The original owner did not change the speedo for the tires.
