Yes it's a 4x4 and I put 1500 springs in it. I also put spring tensioners in it to stiffen it up. toyo proxies and i'm not sure what the wheels are called. best 60ft time is 1.61
Looks like there's some writing on the center cap, a brand maybe that could help. Seen those wheels on a few trucks but I can't find them. Sweet truck by the way, why you sellin?
