This past SEMA Show was one for the ages. So many cool and custom vehicles on display will several new 4x4s competing for the spotlight.  Among them the 2020 Chevy Silverado 2500HD with new styling, new powertrain options and new tech throughout. When it came to building a new HD, Ernie Vole of Ernie's ATC in Vernon Hills, IL had a concept that tweaked our interest. Rather than lifting it sky high and and running 24s or even 28s he wanted to show off the truck's offroad prowess, keep it low and build a truck capable of bombing down a trail along the Baja peninsula.

Ernie's no stranger to building functional SEMA trucks, from prerunner trucks and offroad Jeeps to his most memorable ride the original Stubby F350 that graced the cover of Four Wheeler Magazine years ago. For this 2020 HD he needed the right suspension so he turned to BDS for the (preproduction) 2.5" coilover conversion system to ditch the factory torsion bars and UCA/LCA and upgrade to FOX 2.5 DSC coilovers, BDS chromoly UCAs and HD internally gusseted LCAs. Along with that FOX 2.0 IFP bump stops and a full width BDS skid plate. Out back this factory long leafs remain and a custom bed cage was fitted to mount the FOX 2.5 factory series remote resi shocks. This gives clearance for the 35x12.50 Mickey Thompson ATZ P3 tires on 17x9 XD Machete Crawl beadlocks.

The factory bumper was trimmed and supports were added to mount a Baja Designs lightbar along with a roof mounted rack with LP9 lighting all controlled by an sPod relay system. Other notable upgrades include a custom built internal rollbar to mount the PRP restraints and a Pro Eagle big wheel jack mounted in the bed.

Anyone who is a fan in recent years of motorsports will know the name Drive Line Magazine. They’ve taken a fresh approach to covering the automotive scene with editorial, tech, and event coverage spanning across multiple media platforms from digital, social, video and print. Recently they ran an install and review that dug into the tech behind the BDS 2-3″ Coilover Conversion System for the 2011-2019 Chevy/GMC 2500HD trucks.

The owner of the vehicle in the video did not particularly like the nose-down rake that the truck comes with. A basic leveling kit was not satisfying their desire for a smooth ride while being level. This is when they looked to BDS Suspension.

BDS Suspension offers a 2-3″ Coilover Conversion system that does just what this owner was looking for. In order to get the result that the owner wanted, the torsion bar suspension had to be removed and replaced with the 2-3″ Coilover Conversion. This Coilover Conversion used FOX factory series 2.5 coilvoers with remote DSC (dual speed compression) adjustment to offer adjustable damping for the best possible ride quality on and off-road. In order to keep the truck as level as possible, the owner decided to keep the springs the way they are from the factory and switched over to the FOX 2.0 Series shocks.  The video walks through the set up and proves why going with the coilover is a significant upgrade over the torsion bar setup.

Full Product Announcement:

A few months back BDS Suspension introduced the 6.5" coilover conversion high clearance systems, the latest performance option for the 2011-2017 Chevy Silverado HD and GMC Sierra/Denali HD trucks giving next level of performance and comfort to truck owners. These systems allows HD owners the ability to eliminate the rough riding traditional torsion bar suspension in favor of FOX 2.5 factory series remote DSC coilovers and combines them with the tried and true BDS high clearance IFS systems to truely unmatched performance on and offroad. For trucks already equipped with the non-coilover BDS 4.5" and 6.5" High Clearance Systems BDS is now offering an upgrade kit with all the components needed to convert over to the 6.5" coilover setup.

At the heart of this upgrade is a pair of FOX 2.5 Factory Series Coilover with remote DSC reservoir. These coilovers offer vastly superior dampening for impressive capability to soak up the harshest terrains offroad while offering comfort on your daily commute. These FOX coilovers feature a smooth bore and honed seamless alloy body, 7/8" hardened stainless steel shaft, FOX coil springs, black anodized machined 6061-T6 billet aluminum mounts and FOX’s DSC (dual speed compression) adjustment technology. The DSC adjustment allows for easy adjustment of the vehicle’s suspension compression dampening to dial in the ideal ride performance to soak up the bumps, both large and small. The DSC has 12 adjustment points for the high speed compression as well as 10 adjustment points for the low speed compression allowing you to make large or small changes to further improve your performance. Adjustments can be made by simply twisting the "blue" high speed and "gold" low speed compression knobs located on the end of the remote reservoir of the FOX 2.5 coilovers. No tools or shop adjustments needed, allowing you to tune the suspension out on the trail. The coilovers come fully assembled, preset for 6.5" of lift for optimal wheel travel. To mount the coilovers BDS supplies a bolt-on bracket that installs on the frame in the shock mount location. A weld-in support gusset is used to reinforce the upper mount, however still allows the kit to be completely reversible if the owner ever chooses to revert back to the torsion bar style suspension and upgrade the suspension on another truck.

In addition to replacing the factory torsion bars, the upper and lower control arms are upgraded to improved strength, travel, and accommodate the new coilovers. The uppers are the new performance upper control arms designed specifically for this system to integrate with the 2.5 coilovers. The arms are fabricated from large 1.5" OD x .120-wall chromoly tubing, fully TIG welded for the highest quality, strength and durability. The arms utilize premium Moog brand ball joints and factory style rubber bushings for smooth, quiet operation and superior durability when compared to arms with uni-balls, poly bushings or heims. The ball joint cups are repositioned for optimal performance allowing a 30% improvement in wheel travel. These upper control arms are finished in a durable black powdercoat and include a billet aluminum ball joint dust cap. The control arms come fully assembled for easy install right out of the box. To compliment the uppers, the new lower control arms are built from high strength steel, fully boxed with internally gusseted. These lower arms integrate new reinforced lower coilover mounts and similar to the uppers use durometer specific rubber bushings at the frame mount and high quality Moog ball joints at the knuckle mount for quiet, low maintenance operation.

If you're looking to get more out of your BDS equipped late model HD then take it to the next level with this 6.5" coilover upgrade kit from BDS Suspension and FOX.

2011-2015 Chevy/GMC 2500HD 4WD 4.5″ Lift Kits

Coldwater, MI—January 12, 2015— BDS Suspension expands its suspension offerings with new 4.5″ high clearance no torsion bar drop suspension systems for the 2011-2015 Chevy/GMC 2500HD 4WD trucks. Much like the larger 6.5″ systems currently offered these new 4.5″ lift kits are designed to maximize ground clearance, improve offroad capability and and perform flawlessly on the highway at a more modest lift height able to clear 35″ tires.

The 4.5″ lift system is designed to integrate flawlessly with the new electronic stability control (ESC) systems. Up front the kit utilizes a pair of one-piece 1/4″ steel high clearance crossmembers, differential relocation brackets, heavy duty differential skid plate, support brace, and front BDS-branded skid plate to create a sturdy subframe and improved offroad protection. A pair of CNC-machined ductile iron steering knuckles dwarf the factory units and position off the stock upper arm and relocated lower arm mounts without increasing track width. To further increase the ground clearance over other kits this 4.5″ system tucks the torsion bars up tight to the chassis using a pair of torsion bar relocation brackets that key off the factory lower A-arm. This design maximizes break over ground clearance to keep you from getting high centered offroad as well as gives a clean streamline appearance. Extended DOT compliant braided stainless steel brake lines are supplied to all full suspension travel, longer links to allow the sway bar to function properly and your choice of BDS 5500 or Fox 2.0 gas shocks at all 4 corners.

Out back the kit is offered with 2″ or 3″ rear block and u-bolt kits to achieve your designed stance. As with all BDS suspension systems this new 4.5″ high clearance lift kit is backed by the Factory Protection Plus Program offering BDS’s exclusive no fine print warranty and a 5-year 60,000 mile drivetrain warranty free of charge.
