6 Inch Lift Kit | Dodge Ram 2500 (09-13)/3500 (09-12) 4WD | Diesel

Built for diesel truck owners who need serious ground clearance and load-carrying capability without compromising factory geometry. This BDS 6-inch lift kit raises your Ram 2500 or 3500 diesel above the stock stance, giving you room for larger tires and a commanding view of the road — while precision-engineered components preserve your driveline angles and suspension travel.

What you get up front

• BDS upper control arms — engineered with caster correction to maintain factory-correct steering geometry and eliminate the aggressive caster angle that causes premature tire wear and steering heaviness on lifted trucks.
• Front coil springs — matched to your shock choice and axle upgrade, delivering the lift while keeping suspension dynamics predictable.
• Brake line extensions — so your hydraulic system stays compliant and responsive as the front end rises.

Out back

Choose your rear architecture: block kit (solid, bolt-on blocks under the axle with your choice of 3-1/2" or 4" axle housings) or leaf springs (4" axle only), both paired with matching shock tiers. The block kit keeps things straightforward; leaf springs give you added compliance and load-leveling for heavy payloads.

Pick your shocks

• BDS NX2 Nitro — comfortable daily-driver performance, proven reliability, and smooth damping that soaks up road imperfections without fussiness.
• FOX 2.0 Performance Series — premium off-road tuning with ultra-smooth rod and a bypass design that handles ruts, rocks, and washboard while staying composed on pavement.

Important notes

• This kit is engineered for 4WD Ram 2500 (2009–2013) and Ram 3500 (2009–2012) with diesel powerplants. Single-rear-wheel (SRW) 3500s are supported; dual-rear-wheel (DRW) trucks require a different kit.
• Choose your axle upgrade at checkout: 3-1/2" or 4" housings. The 4" option provides additional strength for extreme duty and supports maximum tire clearance.
• Block kit and leaf-spring configurations are available separately; block kits are the quickest install, while leaf springs are ideal if you regularly haul near payload limits.
• Ensure your current wheel backspacing and offset are compatible with your intended tire size after the lift. BDS specs your max sidewall — consult your tire retailer.
• Diesel engines in these years may require transfer-case re-indexing after install to maintain smooth shift quality; your installer will confirm.
