When I had originally put the 3.5" RK lift on I had it paired with 35" tires. I recently upgraded to 37s and now at full flex they rub pretty hard. Do I need to install extended bump stops or is this normal?
stock or flat flares? If flat flares, you will need around a 3 in. bump stop. If you are running the stockers you will need 4 in. bump stops. As far as where to buy, I like Northridge...
