For 35" axle spacing and axles up to 8,000 lbs. capacity. 26.00" Double eye springs - tandem axles. The E-Z Flex equalizer in this kit (PN 013-144-06) can replace existing 013-122-02 equalizers AFFORDABLE SOLUTION Delivers the smooth ride and performance of a premium suspension at a fraction of the cost. INNOVATIVE SUSPENSION DESIGN E-Z Flex is constructed using a resilient rubber core that is permanently held between two equalizer arms. Unaffected by the elements, this core has been scientifically formulated to provide optimal dampening characteristics and long fatigue life. RETAINS AXLE EQUALIZATION E-Z Flex is mounted to a standard hanger which provides a pivot point for equalization of the axles. Suspension systems without this hanger-to-pivot-point relationship sacrifice the ability of the axles to equalize over uneven terrain. During travel, the E-Z Flex System continuously pivots and compresses to isolate and absorb damaging road shocks before they are sent to the trailer frame and its contents. SIMPLE INSTALLATION Retrofits to existing leaf spring axles that use 013-122 style equalizers. Requires no welding, grinding, or cutting of the trailer frame or axle hangers. Maintains the trailer's original ride height. ROBUST COMPONENTS Standard grease zerks and wet bolts provide easy lubrication for an added level of protection and serviceability. Bronze bushings and heavy duty 1/2" thick shackle links deliver optimum performance, durability, and product life.
