Features to know about

Smooth Out the Rough Stuff: BP-51 Bypass Damping That Adapts with You

Stock shocks can’t keep up when the road turns rough. The BP-51 coilovers and shocks use an internal bypass design that soaks up chatter through the middle of the stroke but firms up on big hits. You get a smoother ride on washboard pavement and more control when you hit sharp dips or ruts. The remote reservoir keeps oil temperatures steady so damping stays consistent on long, punishing trail days.

Dial In Your Ride Anywhere: Easy, On-Vehicle Adjustability

Tuning your suspension shouldn’t mean tearing it apart. Each BP-51 coilover and shock has compression and rebound knobs you can adjust by hand—no tools, no removal. You can soften things up for daily driving or firm them for off-road runs in just seconds. It’s an easy way to keep your setup matched to whatever terrain or load you’re running that day.

Lift and Level for Front-End Upgrades: 2-1/2" of Height Support

When you’ve got extra weight up front, this kit adds 2-1/2" of front lift and is tuned to support up to 330 lbs without changing the rear stance. That means your suspension geometry stays balanced and your ride height stays level even with bumpers, winches, or recovery gear installed. Steering feels natural, and headlight aim stays right where it should.

Keep Suspension Angles Correct: Upgraded Geometry with Upper Control Arms

Lifting the front can throw off suspension angles if you don’t correct them. The included upper control arms restore proper geometry so steering response feels tight and components don’t wear unevenly. Forged arms with grease-free bushings and high-strength ball joints deliver a durable, low-maintenance setup that holds alignment and handles better on the road and over rough ground.

Everything You Need, Ready to Bolt On

This system comes complete with matched BP-51 coilovers, shocks, fit kits, mounting hardware, and upper control arms so everything bolts up cleanly without hunting for extra parts. The components are aluminum with a hard anodized finish to shed heat fast and resist corrosion, giving you a reliable suspension upgrade built for years of trail use.
