Hotchkis Sport Suspension 17367 Heavy Duty Mopar Shackle Kit for Dodge Chrysler and Plymouth Leaf Spring Cars. These shackles are made from .250 in. steel and are finished in gloss black powder coat and includes 1 in. leaf spring bushings. What s really cool about these shackles is the design. The bolts are specially machined by Hotchkis as direct copies of the original shackle bolts consisting of a large machined shoulder that acts as the bushing sleeve and is machined down to lock the opposite shackle plate in position. Many other aftermarket shackles on the market use a bushing sleeve and a smaller bolt to achieve this which reduces strength. The kit includes grade 8 hardware nylock nuts polyurethane bushings grease and contains 1 in. leaf spring bushings which are commonly used on many Dodge Plymouth applications. Please ensure your car has 1 in. bushings. These are a perfect upgrade to your Hotchkis Leaf Springs for the B&E Body Cars.
