All Leaf Springs are not created equal! Length, Material, Thickness, Clamp Location, Types of pads, and number of leafs all contribute to the effectiveness of the spring. All of our springs are designed to achieve the following goal:
Lower the ride height and provide additional spring rate.
Reduce, if not eliminate, wheel hop during launch! Wheel hop can be a result of many factors, however springs have a great deal to do with it. Our forward segment of the leaf is designed to control rap up, which is left unchecked and will cause the leaf to load and unload resulting in wheel hop.
Control excessive squatting.
Note: The L-16 Will lower the rear ride height about 1-1/4 to 1-1/2 inches. The spring has a softer rate then L-2 or L-3 leafs. L-16 is used for street (cruising) or drag race with traction bar applications.
Category 5 Rear Leaf Springs
CAT-5 leafs are special leaf springs with spherical bearings installed in the front and rear eyelets rather than bushings. Del-A-Lum bushings are supplied in the rear frame area along with shackles and specific hardware. CAT-5 leaves are considered to be the ultimate leaf spring combination.
Reasons to use CAT-5 Leaf Springs:
1. Using spherical bearings in the eyelets allow the rear end to tilt during corners keeping the inside and outside tire flat on the pavement. This also works over bumps reducing the sharpness.
2. The spherical bearing and bushing combination do not allow the leaf springs to move laterally. Standard rubber and polyurethane bushings do,therefore using a CAT-5 system eliminates the use of a panhard rod or any other lateral-locating device.
The end result is a smoother ride with the ability to put power down during corner exit.
NOTE: Del-A-Lum bushings are recommended for making the system work as intended. However, street applications may use rubber or polyurethane bushings rather than Del-A-Lum. Keep in mind, the end result will not be the same.
