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.

Project Raider vs Bundy Hill Offroad Park

Over the last couple months BDS’s Project Raider has grown up. This 2015 Chevy Silverado 2500HD Duramax started out as the test mule for development and product testing for the BDS 2.5″ coilover conversion system (torsion bar delete kit). With development and testing complete the truck was built up to debut the new system at the 2015 SEMA Show. That build up consisted of a modified N-Fab front bumper, nerf steps and a custom built rear bumper. 35″ Nitto Exo Grapplers were mounted on 20″ Fuel Hostage IIIs to improve the stance along with a T-Rex mesh grille, Bushwacker fender flares, Zroadz LED lighting and an Extang tonneau covers. Performance add-ons included an AFe cold air intake and Bully Dog programmer. Finishing off the truck was a custom “adventure edition” vehicle wrap.

After spending the past year pulling tow rig duties for BDS, attending events and making dealer stops from coast to coast, hitting trails and playing at the sand dunes it was time for this truck to go back under the knife for something bigger and badder. What the BDS R&D team came up with was a 6.5″ coilover conversion high clearance system, taking all the benefits of the tried and true high clearance IFS system, now with the torsion bar deleting FOX 2.5 DSC coilover conversion with high strength upper and lower control arms.

Initially Project Raider 2.0 was set up on a set of 37×12.50 M-16s on 20×9 Fuel Hostage IIIs which looked undersized for how the truck was set up with bumper and fender mods. From there the truck went to 38×13.50 Nitto Trails on 20×10 Fuel Vapors that gave it a strong stance and comfortable amount of clearance. These days the HD is running a set of 40×15.50 NittoTrail Grapplers on the 20×10 Fuel Vapors, which with the additional fender modifications do fit for on-road and mild off-road use. Check out the video of it in action out on the trails at Bundy Hill Offroad Park in Jerome, MI pretending it was a Jeep navigating the obstacles, rock garden and throwing mud in some epic drifts.

BDS Suspension expanded its FOX coilover lineup with 6.5" coilover conversion high clearance systems for the 2011-2016 Chevy Silverado HD and GMC Sierra/Denali HD trucks giving a new level of performance and comfort to truck owners. This new systems joins the existing 2.5" coilover conversion allowing HD owners the ability to eliminate the rough riding traditional torsion bar suspension in favor of FOX 2.5 factory series remote DSC coilovers. This system builds on the tried and true BDS high clearance IFS systems now integrating the coilover conversion for improved performance over any terrain. These new coilover systems have been engineered and tested for improved comfort, fade free performance, and increased suspension travel.

The new 6.5" coilover system is a game changer for HD performance. At the heart of the system 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 new performance series 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 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.

Along with the coilover conversion, this 6.5" system includes a pair of one-piece laser cut high clearance crossmembers, CNC machined ductile iron steering knuckles to correct tie rod angles, heavy duty front skid plate and differential skid plate to increase protection, multipoint differential relocation brackets to secure differential and correct CV axle angles, longer sway bar links and braided stainless steel extended brake lines. In the rear, BDS offer both a 3" and 5" rear block and u-bolt kit to lift and level the stance. The 5" rear block kit includes a u-bolt flip kit with new spring plate and the preferred round u-bolts for increased strength and ground clearance. To compliment the performance in the front this system includes precision tuned FOX 2.0 IFP gas shocks in the rear. This system allows for up to 37" tires to be installed.

This industry only show boasts something for every automotive enthusiast, from hotrodders to racers, lifted trucks, lowrider, powersports to restoration. The 4-day show is held at the beginning of November each year bringing in around 100,000 buyers/shops from around the world to check out the latest aftermarket parts from over 1000 vendors.

This is BDS’s 7th year attending the industry show and each the show gets bigger, pushing the limits, and more over the top with manufacturers stepping up to wow the attendees with over-the-top builds, new technology and the latest innovations. BDS has found a home in booth #30192, a 25×80′ booth along the outside of the South Hall, upper level where we team up with sister companies Zone Offroad Products and JKS Manufacturing to show off cool rides and the latest suspension and accessories for trucks and Jeeps. Each year our booth is designed around a theme, over the year’s we’ve build tailgate parties to camping scenes, but this year we kept with a simple one, black and tan. Tan carpet, tan and black vehicles flexed out throughout on tan display rocks, black backdrop banners and a black bar serving beers all week long.

It could be the free beer, the cool builds, new products or even the personel working the booth, but this year once again was a hugely success show for BDS Suspension and the other brands of Sport Truck USA. Scattered throughout the booth we had several vehicles on display including, #projectraider a 2015 Chevy Silverado 2500HD to debut our 3” mid-travel coilover conversion system. Going down the line the Ultimate Adventure conquering #crawlorado – an LS2 powered BDS long arm equipped 1st gen Colorado, a 2014 Jeep Wrangler #AdventureEditionJK and #PlatinumChase, a 2015 Ford F250 Platinum running the BDS 8” coilover conversion system. Along with debuting the GM HD coilover conversion (available Spring 2016) and new products like F250 C/O and new Colorado/Canyon kits (available now), BDS was showing off the next generation spring loaded traction bars designed with adjustable resistance in a full floating bar for a great ride when you want it, and the ability to put the power down when you need it. The new tractions bars got the attention of many at the show and ever took home Diesel Tech Magazine’s Show Stopper Award for most innovative new product. We’ll have more info on these traction bars once they hit the market in Spring 2016. Throughout the show dealers stopped by to check out the new products and catch up with the team over a beer. The booth was buzzing with plenty of celebrity appearances from 4wheeling royalty, monster truck drivers, TV personalities and some of the most well known shops from around the country. A big thanks to everyone that came by the BDS/Zone/JKS Booth at SEMA 2015.

Around the expansive show BDS had nearly 50 trucks and Jeeps on display in featured vehicles spots and other vendor booths. To say BDS was well represented this year was an understatement. We had our best year yet showing at SEMA with several amazing builds sporting BDS suspension and accessories. A big thank you to everyone that made it out to show off their BDS -equipped trucks at SEMA.
