My son has a 98 Ram 1500 Laramie 4x4. Can someone tell me what size the stock blocks were under the the leaf springs of the rear axle? When we bought it, it had a mild lift on it with 33" tires. We are finding out that the heavy tires and the lift are causing some major stress on the drive train and he wants to bring it back down to the stock level with 31" tires. If someone has a picture of their rear axle and leaf springs or can just tell me the size of the block, I would appreciate it.
