Description
Boosts Your Truck’s On-Road Performance. Equipping your truck with this Ground Force 2.50-Inch Rear Lowering Shackle Kit will help convert it into a reliable on-road vehicle. With this installed, your truck’s rear ride height will decrease by 2.50 inches. The lowered ride height reduces the amount of air passing underneath your vehicle, reducing aerodynamic drag. This makes it much easier for you to control your truck on the streets. Furthermore, with your truck sitting closer to the ground, you’ll be able to experience a more stable ride.
High-Strength Steel Construction. To endure your truck’s stressful driving conditions, Ground Force made this kit’s shackles out of durable steel. With this high-strength construction, the shackles are able to withstand impacts and extreme temperature conditions without easily bending, cracking, or breaking. Plus, they are applied with a black powder coat finish to enhance their protection against rust and corrosion.
Direct Bolt-On Installation. Setting up this rear lowering shackle kit is easy especially if you have the right tools and mechanical skills. For greater installation convenience, this kit’s shackles are designed to directly bolt onto your truck’s existing points and don’t require any complicated modifications.
Supported by a Limited Lifetime Warranty. For your peace of mind, this rear lowering shackle kit is supported by a limited lifetime warranty. When filing a warranty claim, please comply with all the warranty terms and conditions. For more warranty information, you may contact customer service.
Application. This Ground Force 2.50-Inch Rear Lowering Shackle Kit is tailored to fit 2007-2013 GMC Sierra 1500 Extended Cab and Crew Cab models.
