Abstract

An anti-roll suspension stabilizer for a vehicle having a leaf spring suspension system. The device features an elongated stabilizing spring communicating roll resistance to the attached axle of the vehicle at a center section and concurrent force at each of two ends of the stabilizing spring to the leaf spring of the vehicle through an attachment thereto using a shackle. Adjustment of the device is achieved by use of a plurality of mounting apertures for the shackles located at varying distances from the center of the stabilizing spring thereby allowing for adjustment by the user for desired performance characteristics. Further force adjustment is achieved using one or a combination of an optional axle spacer which can be made from one or both of solid rubber like material, or a pneumatic pillow which can vary in dimension, which would be located at the center section of the stabilizing spring where it communicates with the axle.

Dependent claims

A vehicle suspension stabilizing device for use in combination with a vehicle suspension having a leaf spring attached to an axle, comprising:

an elongated stabilizer having an upper surface, a lower surface, two ends, and a center section;
said elongated stabilizer attachable at said center section, to a fixed position above said axle and above a top surface of said leaf spring;
means to maintain said elongated stabilizer deflected transversely toward said lower surface when paid center section is attached above said axle;
said two ends providing a calculated biasing force from each of said two ends toward said upper surface, when said elongated stabilizer is deflected transversely at said center section toward said lower surface;
means to communicate said calculated biasing force from each of said two ends of said elongated stabilizer to the bottom surface of said leaf spring, at each of two corresponding ends of said leaf spring;
and
a spacer, said spacer positionable between said elongated stabilizer and said axle when said elongated stabilizer is in said fixed position, said spacer providing a means for adjustment of the amount of said calculated biasing force provided by said two ends of said elongated stabilizer by varying the dimension of said spacer.
