A BDS Suspension lift kit raises your truck or SUV to make room for larger tires and add ground clearance, while correcting the geometry that matters for a good ride and safe handling. Each kit is engineered for the vehicle it fits, with components chosen to restore steering, driveline and suspension angles after the lift. BDS kits are offered with a choice of shock packages, so you can match the ride to how you use your vehicle, from daily driving and towing to trail and off-road use.
