Im getting ready to buy a budget friendly lift kit and came across the ironman nitro gas 2" lift kit on sale for $600. Toyota 4Runner 2003+/Lexus GX470/GX460 Nitro Gas 2" Suspension Kit Performance Load (0-660LBS) *SAVE AN EXTRA 25% WITH PROMO CODE FROZENBEEF25. IWould like to get some feedbacks from anyone running them. I found a lot of info on their MRR but not much on the nitro.
