Features to know about

Handle Extra Gear Without Losing Ride Control: 2-1/2" Front and 2" Rear Lift

When you’re carrying gear up front and in back, a sagging stance can make your ride feel off balance. This BP-51 suspension kit adds 2-1/2" of lift in front and 2" in the rear, tuned specifically for vehicles loaded with bumpers, winches, drawers, or rooftop tents. The front coilovers handle up to 330 lbs of added weight, while the rear coils support 440 lbs of constant load. It keeps your stance level and your ride confident, even when fully loaded with equipment.

Fine-Tune How It Feels on the Trail or Highway: On-Truck Compression and Rebound Adjustability

When every road feels different, being able to dial in your suspension makes all the difference. The BP-51 coilovers and shocks include 10-stage compression and rebound adjusters you can set right on the vehicle. Bump up firmness for rough trails or back it off for smooth highway runs—no tools needed. With this kind of control, you can match comfort and performance to whatever terrain you’re tackling that day.

Smooth Over Rough Ground: Internal Bypass Dampers with Remote Reservoirs

You don’t have to choose between comfort and control. BP-51’s internal bypass design keeps small bumps smooth while staying firm on big hits. Remote reservoirs help manage heat for consistent damping on long drives or off-road climbs. The result is a suspension that feels composed instead of harsh, letting it soak up terrain changes without tossing you around.

Keep Geometry in Check After the Lift: Upgraded Upper Control Arms

A higher stance can throw off alignment and steering feel if geometry isn’t corrected. This kit includes upgraded upper control arms that restore proper suspension angles after the lift. That means sharper steering response, better handling, and less wear on other suspension parts over time. Forged arms with grease-free bushings and high-strength ball joints keep things tight and low-maintenance for the long haul.

Built for Real-World Loads: Durable Components That Work Together

Everything in this setup is engineered to perform as a system under real-world weight. From BP-51 coilovers (open length 545 mm, closed length 439 mm) to matched rear shocks (open 607.5 mm, closed 385 mm) and coil springs rated at 318 lbf/in, each component is tuned to maintain lift and control under load. The direct-fit design bolts to factory mounts without cutting or welding, making it a solid upgrade for carrying gear with confidence.
