I have there 2" lift and it is about 12-14 years old. It has been abused a lot and it still works great to this day. I had the frame crack, body crack, power steering bracket brake but never had a problem with the suspension kit. I would like to upgrade to the 3" but I don't have the time to do it right now. But given the 2" with a 2 1/2" homemade body lift, it runs 31 BFG Muds and goes anywhere being locked up front & rear and lower t-case gears. You can't beat the Calmini lift for dependibility, durability, and cost.
