I am going to be buying the Camburg 4"Spindles for my 2012 Pre-Runner double cab long bed. I plan on getting the 5100's for the rear and possibly the front as well. I want to place blocks in the rear but I am not sure what size. My question to you all is what size blocks will I need for the rear to make the truck sit level and/or issues you have had with a similar lift?. The truck is a daily driver 95% of the time with minimal towing/hauling. Any feedback would be appreciated and suggestions on something I may be missing would be good too.
