Daystar Air Bag Cradle Kit KU09140BK 15673 6.00 Daystar Air Bag Cradle Kit KU09140BK
$ 79.99
We want our trucks to do everything. Hit the trails, tow the boat to the river, take us to work and transport the family on long road trips. Adding an air bag system to your full-size truck or SUV has always meant scratching at least one of those off your list. With most air bag systems, the lower air bag mount is placed above the leaf spring significantly reducing wheel travel by design. Your air bag system should compliment your truck, not inhibit its ability. Daystars new Air Bag Cradle* (Patent Pending) mounts to your trucks lower suspension providing more room for the air bag to safely cycle with no loss of overall wheel travel. Inferior lower air bag mounts restrict air bag movement using inadequate space, which can lead to unexpected damage to the air bag. Made from extremely tough Daystar Polyurethane, the Air Bag Cradle allows for full suspension travel, while still allowing the full benefits of your air bag system. The Air Bag Cradle fits most full-size pick up trucks, and SUVs running 6-inch diameter air bags and are made in the USA. Features: Allows For Full Suspension Travel With Air Bag Systems Built From Extremely Tough Daystar Polyurethane Limited Lifetime Warranty Made In The USA!
