US Car Tool have been in business for more than 10 years, providing the Mopar and Hot Rod communities with quality repair tools, chassis reinforcement products, and world-class repair and automotive manufacturing services. These rear plate spring shackles are an excellent substitute for rusty or bent factory rear plate spring shackles. US Car Tool include shouldered bolts of the right size to set the correct bushing width without undue tightening due to nameless replacement shackles. These will provide you with rack height. If your leaf springs droop or you need more clearance space, they can also manufacture to a custom length, adding up to 3 inches to their inventory. Note that a 1-inch shackle will raise the back of your car by 1 inch and provide an approximately 3/8 inches increase in tire clearance. Longer shackles may adversely affect the operation.
