Lippert Equa-Flex Rubberized Equalizer Tandem Axle Kit, Heavy-Duty, 4,000-6,000 lbs.

Road shock should be absorbed by your suspension, not transferred to your precious cargo. The Lippert Equa-Flex Rubberized Suspension System completes this task with flying colors. Equa-Flex was formulated to absorb road vibrations and protect your cargo. Equa-Flex also helps reduce fore-to-aft trailer movement, otherwise knows as chucking. The rougher the road conditions, the better the system performs.Not only does Equa-Flex virtually eliminate damage to your trailer caused by road shock and vibrations, but it protects your precious cargo as well. Equa-Flex delivers a ride that is as smooth as a torsion axle, but is a fraction of the cost.
