Using high-performance Aeon rubber springs, this kit provides a progressive spring rate that automatically adjusts to heavy loads and uneven road conditions.

• Zero Maintenance: Durable rubber construction with no moving parts or air pressure to maintain.
• Improved Stability: Significantly reduces body roll and improves overall handling while towing heavy trailers.
• Lifetime Warranty: Built for long-term durability and backed by a manufacturer lifetime warranty.
