I am looking to put a 2" lift block on the rear of my 2003 Ram QC 1500. I was looking at tsliftkits.com's lift blocks because they are the extruded aluminum lift blocks. I am not sure if there is any type of difference between the two sets of lift blocks they have. I cant find anything that sites a specific block for the truck. If anyone knows where I can get a definate set of blocks for my truck, let me know. Check the site and let me know which ones are for my truck. I only know that I have round U-bolts and want a 2" block. Thanks.
