Engineered for Performance From City Streets to Backcountry Trails

Take your HD truck to the next level with the BDS 1832FPE 3-inch FOX 2.5 Coilover Lift Kit, built specifically for 2020–2025 Chevy Silverado and GMC Sierra 2500HD/3500HD trucks running the 6.6L Duramax. Whether you're looking to level out the stance, clear bigger tires, or just want suspension that actually keeps up with your driving style, this kit brings the performance and durability you’re after—without the guesswork. Right out of the box, this system ditches the factory torsion bar setup and replaces it with a purpose-built FOX 2.5 Performance Elite coilover conversion. These coilovers aren’t just about looks—they’re tuned for real-world trail abuse and provide a plush ride on pavement. The added travel is noticeable the first time you hit a rut or dip, soaking up the bumps while keeping the truck planted and controlled. Plus, with remote reservoirs and dual speed compression (DSC) adjusters, you can fine-tune the shocks depending on whether you're daily driving or hammering through dirt roads.

Proven Strength That Holds Up Under Any Load

The kit doesn’t stop at shocks. BDS includes upgraded upper and lower control arms to match the new travel range and geometry. The uppers are crafted from 1.5-inch OD tubing and TIG welded for maximum strength. Down below, the boxed steel lower arms are gusseted internally and designed to handle whatever you throw their way—mud, rocks, hauling, or heavy tow loads. Everything’s finished off with maintenance-free bushings and heavy-duty ball joints for long-term reliability. In the rear, BDS supplies FOX 2.0 Series rear shocks to round out the setup. All hardware is included, and the entire system bolts on with no cutting or welding required, making installation as straightforward as it gets for a kit of this caliber. This isn’t just a lift—it’s a performance overhaul. So, whether you're exploring the backcountry or towing on the jobsite, this kit is ready for whatever you throw at it.
