Description
Leaf Spring Enhancement. The RoadActive Suspension Leaf Spring Enhancement Kit is engineered to reduce rear squat, improve ride quality, and enhance vehicle stability under load. It adds significant strength to factory leaf springs by using a variable-rate tension coil spring that progressively engages as weight is applied, preventing sag and improving control during towing and hauling.
Construction and Appearance. The kit features durable coil springs and precision-engineered brackets designed to integrate securely with the rear leaf springs. Components have a corrosion-resistant black finish to ensure longevity and reliability under various environmental conditions.
Installation. Installation is straightforward and typically takes about 45 to 60 minutes using basic hand tools and jack stands. No drilling or airlines are required, making it accessible for most DIY enthusiasts.
Warranty. This product is backed by a 5-year limited warranty covering defects in materials and workmanship.
Application. Specifically designed to fit the 2005-2023 4WD Toyota Tacoma with the rear axle located below the leaf springs. Note that it is not compatible with Tacoma models equipped with TRD Pro shocks.
