BDS Suspension is now shipping a full lineup of lift kits and accessories for the 2018 Chevy and GMC 2500/3500 HD trucks. These kits are designed to improve the offroad capability, handling and ground clearance of your late model HD while maintaining on road comfort. 2018 Chevy/GMC HD product offerings include:

2.5" Coilover Conversion Systems: BDS offers game changing performance with this 2.5" coilover conversion system for the late model HD trucks. Designed to eliminate the factory torsion bars and convert over to FOX 2.5 factory series coilovers with DSC adjustment, this system offers unmatched high speed performance, on-off road ride quality, and capability. Along with the coilovers these systems include heavy duty upper and lower control arms to allow for 30% increase in front suspension travel. The BDS upper arms are built from heavy wall 1.5" OD tubing with durometer specific rubber bushings and MOOG ball joints. The lowers are BDS heavy duty replacements, full boxed and internally gusseted. These arms use rubber frame mount rubber bushings and heavy duty ball joints for long life and easy maintenance. Also included are bolt in upper coilover frame mount and weld-in support gussets, differential drop spacers, longer sway bar links, rear FOX shocks and a 2" fabricated block kit. This system comes pretuned for 2.5" of lift for optimal compression/droop travel, but ride height can be adjusted between 2-3" of lift by adjusting coilover preload. This kit comfortably fits 34" tires, 35" tires with some trimming.

4.5" High Clearance IFS System:  BDS has built a reputation for quality GM suspension options with their high clearance IFS systems. Designed to improve performance, capability and ground clearance while maintaining ride quality, the 4.5" High Clearance IFS Systems are great option for customers looking for a stout lift kit to comfortable fit 35" tires. These kits integrate flawlessly with the OE installed electronic stability control (ESC) systems for safety and use 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 from getting high centered offroad with the added benefit of providing a clean, streamline appearance without the torsion bars hanging down. 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 precision tuned BDS NX2-series or FOX 2.0 IFP performance gas shocks at all 4 corners. In the rear, this kit is offered with either a 2" or 3" rear block and u-bolt kits to achieve your designed stance.

6.5" High Clearance IFS System: Built off the tried and true BDS High Clearance design, these 6.5" IFS systems carry off many of the same features as the 4.5" lifts offering improved performance and capability while retaining on-road comfort. The 6.5" lift systems utilize heavy duty 1/4" steel, laser cut crossmembers, multipoint differential relocation brackets, heavy duty steering knuckles and differential and front skid plate creating a sturdy subframe and corrected suspension geometry. To further increase the ground clearance over other kits this 6.5" 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 from getting high centered offroad with the added benefit of providing a clean, streamline appearance without the torsion bars hanging down. Finishing out these kits are extended sway bar links, stainless steel braided DOT compliant brake lines and your choice of BDS NX2 gas shocks or FOX 2.0 performance IFP gas shocks at all 4 corners. In the rear, this kit is offered with either a 3" standard block kit or 5" block u-bolt flip kit to achieve your designed stance with room for up to 37" tires to be installed.

6.5" Coilover Conversion High Clearance System: Built to maximize the potential of your late model HD, these new 6.5" coilover systems bring together the strength and reliability of the BDS high clearance IFS systems with the unmatched performance and tunability of the FOX coilover conversion for the late model HDs.  These systems have all the increase ground clearance, improve suspension travel, allow clearance for 37" tires, allow for easy ride quality tuning (using DSC adjuster) on road comfort, and offroad capability. At the heart of these systems are a set of pretuned FOX 2.5 factory series remote reservoir DSC (dual speed compression) adjustable coilovers, heavy duty upper control arms, BDS high clearance crossmembers, internally gusseted lower control arms, multipoint differential relocation brackets and skid plates, extended brake lines, bump stops and sway bar links, upper coilover mounting brackets, ductile iron steering knuckles, rear lift blocks and rear FOX 2.0 shocks. Designed and tested, these system offer unmatched performance for your late model HD across any terrain.

RECOIL Traction Bars: The problem with most traction bars is the fixed length design doesn't follow the arc of the suspension. While they may limit axle wrap, they bind up the suspension to the point the rear suspension it ride horrible. BDS solved this issue with the RECOIL traction bar system. Spring loaded with a full-floating design, these bars are designed to improve traction and limit axle wrap while allowing suspension travel and maintain on-road ride quality. BDS RECOIL traction bars offer you the freedom to tune the spring compression for optimal performance on-road, off-road, towing, or competition pulling. These traction bars can be used on stock height or lifted trucks and work with both lift blocks and replacement leaf spring kits. The bars are built from 2" OD x 3/16" wall steel tubing with a forged flex joint at one end and on the other a full floating end a 3000lb spring rated internal compression spring. This spring can be preloaded using the supplied spanner wrenches to "tune" the stiffness of the traction bar to meet your needs. Vehicle specific mounting brackets make installation a breeze.

    I am looking to lift a 2018 Denali 2500 HD. I am wanting to apply one of your lifts in exchange for advertising the product. I’m sure not many 2018 models contain your products and I would love to get my hands on them and help get your name out there.

    • Carter @ BDS Suspension says:

      Hey Kyle, being that the 2018 Chevy/HD trucks are a carry over from the 2011-2017 models there isn’t a need to get our kit installed on a truck solely for the purpose of saying we have our kit on an ’18. That said we do have a sponsorship program where we occasionally exchange promotional product for promotional builds that with plans in place for national exposure at events like SEMA, are part of national corporate marketing campaigns, will be part of TV and magazine project builds etc. You are welcome to submit a detailed proposal outlining your build and promotional plans through our online request form for our team to review at http://bds-suspension.com/sponsorships

    I own a 2018 2500HD Denali Duramax. How do I know whether I need the kit with or without overload?

    • Carter @ BDS Suspension says:

      Hi Andy, thanks for your interest in BDS. To determine which rear box kit you’ll need take a look at your truck’s rear suspension. If there is a separate leaf mounted on top of the main leaf pack then you have the factory overload, if its just the main leaf pack on your truck then you’ll want to order for the non-overload. While the lift block is the same between truck, the u-bolts supplied for the trucks with factory overload spring are longer to accommodate the extra length of the spring assembly.

    Do you know the wheel and tire specs for the coilover conversion Denali such as the size and offset? Also was there any trimming needed?

    Reply
    • Carter @ BDS Suspension says:

      Hey David, this customer chose to run 37×13.50 Toyo M/Ts on 22×10 Hostile Alpha (-25mm offset) with out 6.5″ Coilover Conversion System. This wheel/tire spec is outside of our official recommendation and I do believe some trimming was necessary to clear in all driving situations (on and off-road).
