Abstract
A traction device is provided that includes a rigid front mount assembly that may be clamped to or around the vehicle's leaf spring, thereby creating a positive displacement point for torque transmitted from the rear axle through a telescoping linkage. An advantageous shock absorption element associated with the telescoping linkage cushions forces transmitted therethrough. Free travel and pre-load adjustments are made quick and easy through a readily accessible adjustment mechanism. A preferred bracket design is also provided which ensures optimal force transmission and enhanced system strength and reliability. The traction device of the present disclosure may be included in original vehicle fabrication and assembly, or may be readily installed on existing vehicles without the need for welding or modifications to the chassis or rear axle housing.
