What you get up front

• Front coil-over kit — raises the front axle while maintaining OE suspension geometry and caster correction for stable handling.
• Rear block kit or leaf spring upgrade — lifts the rear to match the front and keeps your truck level under load.

Out back

Choose between a block kit with add-a-leaf springs for a classic lift, or full replacement leaf springs for a refined ride. Both options handle towing and payload without sagging.

Pick your shocks

• BDS NX2 Nitro Series — proven comfort for daily driving and occasional off-road work; paired with our most popular lift configuration.
• FOX 2.0 Performance Series — adjustable damping for precise tuning; ideal if you're mixing highway miles with rough terrain.
