  • Easier Tuning on the Trail: Hand-adjust compression and rebound to dial in comfort and control without teardown.
  • Smoother, More Controlled Drive: Internal bypass design softens small bumps but firms up at extremes for confident handling.

  • Long-Term Durability: Forged arms, grease-free bushings, and high-strength ball joints hold up to tough use with less upkeep.

Features to know about

Handle Heavy Builds Without Losing Lift: 2-1/2" Front and 2" Rear Suspension Support

When you’ve added bumpers, a winch, or gear front and rear, staying level matters. This BP-51 suspension kit adds 2-1/2" of lift up front and 2" in the rear. It’s tuned to hold 330 lbs up front and a constant 880 lbs in the rear so your stance stays consistent even when fully loaded. The higher-rate rear coils replace the factory springs to keep ride height and control with drawer systems, rooftop tents, or recovery setups.

Dial In Control for Any Terrain: BP-51 Remote-Reservoir Coilovers and Shocks

Every trail and load is different. The BP-51 coilovers and shocks use a bypass design with remote reservoirs to balance comfort and control. You can make 10-stage compression and rebound adjustments by hand, right on the vehicle—no teardown required. Turn it down for a smooth highway ride or firm it up for rough terrain; either way, the suspension stays composed.

Smooth Ride with Real Travel: Internal Bypass Damping

The internal bypass design softens small bumps while firming up at full travel, giving you control without harshness. It’s not just extra lift—it’s suspension that reacts to what the trail delivers. Whether you’re crawling rocks or soaking up washboard roads, your ride feels planted and predictable.

Keep Geometry Right Where It Should Be: Upgraded Upper Control Arms

Lifting changes your suspension angles, but this kit fixes that. The included forged upper control arms restore geometry for better steering response and more even tire wear. Grease-free bushings and high-strength ball joints keep maintenance low while improving handling and durability on every trip.

Built for Long Hauls and Heavy Loads: Durable, Matched Components

Each component in this package is tuned to work together—BP-51 coilovers, rear shocks, high-rate coil springs, and fitting kits all designed as one system. The result is a setup built to handle real weight, maintain ride height, and deliver confidence when loaded down or exploring off pavement.
