BDS Suspension 6" Lift Kit 14-18 Ram 6.7L Cummins 3500 w/ Factory AirHaving a 3500 with the factory air suspension means you have a do it all truck.

Having a 3500 with the factory air suspension means you have a do-it-all truck. Only downside to that is that the suspensions are more complicated. Thankfully, BDS has engineered many options to get your truck lifted up to fit larger wheels and tires. These 6" kits retain full functionality of the factory rear air-ride and on-road comfort while improving offroad capability.

Up front these systems use a pair of progressive rate 6" coil springs to provide the extra height and smooth controlled performance in the harshest of terrains. A forged drop pitman arm is supplied to correct steering angles along with a HD bar drop bracket to re-center the front axle. A pair of sway bar drop brackets reposition the OE sway bar along with extended polyurethane bump stops to correctly limit up travel and brake line brackets to allow full droop. To correct the front suspension geometry at the new height, a pair of heavy duty replacement radius arms are supplied to bolt in place of the factory arms. Two options are available for the front suspension arms, 4-Link Long Arms and Radius Arms. Both are massive upgrade to the factory stamped units, using tubular construction and a lower cam adjustment to dial in front end caster. Also supplied are your choice of BDS NX2 gas shocks or FOX 2.0 performance series IFP gas shocks for improved ride and performance.

At 6" of lift, it is critical to correct the front driveline angle to maintain use of the 4WD. To do this, BDS Suspension provides a heavy duty replacement transmission crossmember as well as a transfer case indexing ring to reposition the front driveline output to allow use of the factory drivelines. In the rear, a 5" lift block and u-bolts are supplied to lift and level the stance along with a heavy duty air bag spacer brackets. This allows the rear suspension to be perform just like it does at factory ride height and maintain full air bag range of motion. The rear suspension is rounded out with your choice of NX2 series or FOX 2.0 shocks.

Front Suspension Arm Options

4 Link Long Arms - The heart of this system is the 4-link conversion that replaces the factory radius arm. Key benefits include to doing this include increased stability, wheel travel, and improved handling across all terrains. The 4-link design limits caster change to less than 1-degree of change throughout wheel travel for better handling, steering control, and overall driveability. Included are a pair of massive frame-mounted brackets precision welded and engineered to locate the new upper and lower control arms to create the optimal suspension geometry for late model RAM trucks. The 4-link brackets are fabricated from 1/4" thick steel and wrap around the frame as well as the factory radius arm brackets to create an extremely sturdy mount for the new arms. Removal of the factory radius arm brackets is not required and allow the brackets to stay intact to speed up the installation time and make these kits reversible. The upper and lower control arms are built from 2" OD x 3/16" wall DOM tubing for the strength to take any abuse you can throw at them. They utilize large 2.5" OD polyurethane bushings to isolate road vibrations and are formed inward to allow for extra tire clearance while repositioning the front axle slightly forward for increase tire clearance to the backside of the front fenders when turned. These arms are finished in a durable textured black powder coating and use grease fittings for easy servicing.

Radius Arms - The 6" Radius Arm Drop System uses a pair of 1/4" thick steel radius arm relocation brackets to reposition the factory radius arms and correct suspension geometry and caster at 6" of lift. These brackets are designed for quick installation and create a stout mounting location for the radius arms by tying into both the factory radius arm frame mount and the side of the frame rails.

Sway Bar Disconnects

This kit allows a standard Ram heavy-duty trucks to enjoy the added articulation of a disconnected sway bar. The new sway bar links are made from 7/8" solid steel bar and feature greaseable, high-misalignment polyurethane bushings. All mounting hardware is included for simple, bolt on installatio

Front Adjustable HD Track Bar

These new track bars are a massive upgrade to the factory unit, constructed from 1-3/8? solid steel stock reinforced with gusseted ends to handle whatever on-road and off-road abuse you can through at it. Adjustments are made at the 1-3/8?-12 fine threaded center turnbuckle with pinchbolt ends to allow easy tuning to properly recenter the front axle for a range of lift heights. The track bar is formed for proper clearance around critical front end components and is designed to easy installation without the need to clearance the factory frame and axle mounts. Both ends use high-durometer polyurethane bushings with thick-walled steel sleeves for strength and reliability. Parts come with a high quality textured black powdercoat finish for a great look and excellent corrosion resistance. The are designed for use on 0-3" of lift and can be used in combination with most aftermarket track bar brackets to be used on taller lift heights.

Great patches for punctures and the proper way to repair a tyre.
Size: 0.16 x 1.42 ,0.24 x 1.77 ,0.35 x 2.36 Inch, Size: 0.16 x 1.42 ,0.24 x 1.77 ,0.35 x 2.36 Inch
Why go to a tire repair shop and spend a fortune when you can do it yourself. However most people don't want to be bothered but for us do it yourselfers this patch set was great. Comes with various patches all in different sizes. If you're not familiar with fixing a tire it's really easy and honestly a scam getting it done. Fun fact the gray glue on the bottom is actually activated when you drive heating up the patch and vulcanizing it to the tire but it doesn't hurt to actually use some rubber cement to seal around the patch to prevent future leaks. I ended up having to use these on one of my motorcycle tires when I ran over a pallet staple, for me the biggest patchwork and once testing and rebeating the tire there was no leakage. Good price for the amount you receive and cost less to repair it yourself than taking it to a shop

Worked Great. Save a Near New Tire
Size: 0.16 x 1.42 ,0.24 x 1.77 ,0.35 x 2.36 Inch
I got these because twice this year I picked up a nail in my motorcycle tire. The local shops want to sell tires so they won't patch any tire no matter how new. I used these on two tires, a steel-belted radial and a bias-ply off-road tire. It worked out great, both have been holding air for months now and by doing it myself I saved hundreds of $$$. These are the best way to pemanently patch a tire that's gotten a smallish puncture.

Good quality, Best for schools and shops.
Size: 0.16 x 1.42 ,0.24 x 1.77 ,0.35 x 2.36 Inch
I bought this butyl repair patch and the quality is good. I brought it to the school where I’m learning automotive repair and used it as a teaching consumable. Many students tried it, and everyone thought it worked very well. One thing I would suggest for individual buyers: pay attention to the size combinations in the package. For most car owners, you may end up using only one size more often. Because of that, this mixed-size packaging is probably more suitable for schools, training programs, or auto repair shops where different sizes are needed regularly. Overall, it’s still a good quality product and performs exactly as expected.

Look very useful
Size: 0.16 x 1.42 ,0.24 x 1.77 ,0.35 x 2.36 Inch
Haven't actually used them yet, but they look like the perfect way to fix a flat. As can be seen they come in various sizes depending on what you will need. All you need to get is some tire patch rubber cement and a good inner tire sealer (I picked up a can of Xtra Seal)
