If you are serious about handling, you’ll need to replace your original tired-out rear springs. These conventional-arched rear leaf springs are your best choice. We have a few different ratings: Standard 120 lbs. for street and high performance applications, or 150 lbs. for more of a competition use. Competition leaf springs with conventional or reverse eyes are designed for a 1-1/4” drop in ride height. Competition leaf springs are also available with a 2” drop. Reverse eye leaf springs greatly reduce spring wrap-up and require larger diameter bushings. Category 5 competition leaf springs (with shackles) are available in reverse eye only and include the highest quality spherical bearings, mounted front and rear in Del-a-lum bushings. These springs allow the rear end to tilt in a corner, keeping both rear tires planted firmly on the ground while providing enhanced rear end control and increased corner exit speed.
