Features to know about

Stay Level with Heavy Builds: 2-1/2" Front / 2" Rear Lift

When you’ve got bumpers, winches, or a full load of gear, this kit keeps your stance right where it should be. The BP-51 suspension lift adds 2-1/2" up front and 2" in the rear, tuned to hold 330 lbs on the nose and a constant 880 lbs out back. It’s built for real overland setups with drawer systems, tents, and recovery gear—all while keeping your ride height steady and handling predictable.

Tune for Any Terrain: On-Vehicle Compression and Rebound Adjustability

Trail or pavement, light or fully packed—this setup lets you dial it in. Each BP-51 coilover and shock features 10-stage compression and rebound adjusters that you can turn by hand. No teardown or tools needed. Whether you’re softening up for rough tracks or firming things for highway miles, you can fine-tune the ride right on the truck.

Smooth Control Over Every Bump: BP-51 Bypass Coilovers and Shocks

The internal bypass design makes small bumps disappear while keeping control at the extremes of travel. That means a composed, planted feel when loaded down or running light. The remote reservoirs keep damping consistent on long hauls or hot days, giving you a suspension that feels balanced and ready for whatever’s next.

Keep Steering Tight and Geometry Right: Upgraded Upper Control Arms

Lifted suspensions can throw off alignment angles—that’s where the included upper control arms come in. They restore proper geometry after the lift so steering response stays crisp and other suspension parts don’t wear prematurely. Forged arms with grease-free bushings and high-strength ball joints make for solid handling and long life without extra maintenance.

Built to Handle the Weight: High-Rate Rear Coils and Matched Components

The rear coil spring rate jumps from an OE 150 lbf/in to 387 lbf/in to handle that constant 880-lb load without squat or wallow. Every part is tuned to work together—BP-51 coilovers up front, BP-51 shocks out back, matched coil springs, fitting kits, and forged UCAs—so the whole setup delivers lift, control, and durability in one integrated system.
