Bought my truck a few months now but I noticed I kinda bottom out on speed bumps and dirt roads. I don't know if truck has a lift kit or if it is original ride height. I'm currently running 31x10.50 x15. I need to replace all my suspension but don't know if I need a lift kit or oem suspension. What is oem ride height? Where could I find suspension kit for my vehicle. It's a 4x4 automatic. Would like to step up to 32x11.50 or 33's. Any and all suggestions would be greatly appreciated.

 

Just found out this info my truck has 4.56 gears. If that would help with tire decision. Truck feels held back also while driving. Like its asking for more.
