6.5" 2011-2019 Chevy Silverado 2500HD/3500HD (w/diesel engine) Fox 2.5 CoilOver Lift Kit by BDS Suspension

Transform the performance of your 2011–2019 Chevy Silverado diesel with the BDS 6.5-inch Coilover Conversion Lift Kit. This premium suspension system replaces the factory torsion bar suspension with FOX 2.5 Performance Elite DSC coilovers, delivering exceptional ride quality, increased suspension travel, and outstanding off-road capability while maintaining confident on-road handling.

Designed for enthusiasts who demand maximum performance, this system completely re-engineers the front suspension with heavy-duty BDS tubular upper control arms, fully boxed and gusseted lower control arms, and precision differential relocation brackets to optimize suspension geometry and CV axle angles. The result is a stronger suspension capable of handling larger tires, rough terrain, and demanding driving conditions.

The included FOX 2.5 Performance Elite coilovers feature large 2.5-inch aluminum bodies, remote reservoirs, and race-proven Internal Floating Piston (IFP) technology for outstanding heat dissipation and fade-free performance. Standard DSC (Dual Speed Compression) adjusters allow independent tuning of both high-speed and low-speed compression, making it easy to fine-tune ride quality for daily driving, towing, or aggressive off-road use.

BDS tubular upper control arms utilize 1.5-inch DOM tubing with indexed ball joint cups to improve suspension travel while maintaining proper ball joint geometry. Fully boxed lower control arms add strength and rigidity while greaseable ball joints and maintenance-free rubber bushings provide long-lasting durability and quiet operation.

In the rear, replacement lift blocks maintain factory ride quality and load capacity while optional 3-inch or 5-inch block configurations allow you to fine-tune your truck's stance. A U-bolt flip kit increases ground clearance, while your choice of FOX 2.0 Performance Series or FOX 2.5 Performance Elite rear shocks completes the suspension package.

Designed to clear up to 37-inch tires, the BDS 727PSS offers premium ride quality, exceptional off-road capability, and the legendary durability BDS Suspension is known for. It is also backed by the BDS Factory Protection Plus Drivetrain Warranty for additional peace of mind.
