True but with 35s I still have plenty of clearance. Last weekend I went out on the trails twice & didn't even come close to bumping anything. I have 11.5" ground clearance at the front dropped crossmember (lowest point) & have about the same from the rear pumpkin which can only be increased with tire size.
Jo the kit costs about $230-240 after tax/shipping or you could just buy the spacers & bolts seperately from Indy. I didn't use anything in the kit except the spacers & bolts. There are some things you may need & I include those in the how-to.
