Dodge Ram 2500 6-Inch Suspension Kit - Four Wheeler Magazine

Dodge Ram 2500 6-Inch Suspension Kit - Long-Armed And Ready Ken Brubaker Senior Editor, Four Wheeler dodge Ram 2500 Suspension passenger Side View Water Photo 9544645 With the combination of the BDS long-arm kit, a set of 37-inch tires, a Fab Fours front bumper with lights, Warn 16.5 winch, and Pro Comp 6x9 off-highway lights, this Mega Cab is ready to hit the trail.

The 6-inch lift is arguably one of the most popular lifts for truck buyers, and it seems to be the bread-and-butter of many suspension companies. It seems like every week we receive a press release from a manufacturer announcing a new 6-inch kit. There are many reasons for this, including the fact that most 6-inch kits allow fitment of the ultra-popular 35- to 37-inch-diameter tire, which is a great all-around size for street or trail.

When Matt Dinelli at Attitude Performance called and asked if we wanted to hang out while he installed BDS Suspension's new 6-inch long-arm kit on a Dodge Ram Mega Cab, we dropped what we were doing (it's too bad we were looking at a new laptop) and took off for his Arlington Heights, Illinois, facility.

The '06-'07 Dodge Ram Mega Cab and the '03-'07 Ram 2500 are basically the same vehicle underneath, so what you're about to read pertains to both vehicles. Read on to get an inside look at what's included in the BDS kit and how it works.

PhotosView Slideshow Here are the parts included in the BDS kit we installed. This is the top-of-the-line kit for the Ram 2500/Mega Cab. BDS offers four different kits for these vehicles including a short-arm kit. Depending on the kit, you'll get either blocks or springs for the rear. All kits offer double-powdercoated bracketry with clearcoat to ensure a long-lasting finish. 1. A dropped forged pitman arm is included to maintain steering angles. 2. New lower control-arm mounting brackets mount 25 5/8 inches further rearward on the frame than the stock lower control-arm brackets. After new holes are drilled, they're fastened to the frame using supplied 9/16x5-inch bolts. 3. On the passenger side, there's an electrical module that interferes with the mounting of the new lower control-arm bracket. We chose to leave it in the same factory location by just spacing it out from the frame. 4. The new longer lower control arms mount to the stock axle-mounting locations using the OE bolts. The new lower control arms feature greasable bushings, so the grease fittings need to be rotated downward for easy access. 5. The new upper control-arm relocation brackets are positioned over the OE upper control-arm brackets, and holes are drilled for the mounting hardware. 6. Here you can see the completed driver-side upper control-arm relocation bracket assembly. Each bracket assembly utilizes five beefy 9/16-inch bolts and a spacer sleeve. 7. The rear of the new upper control arms mount to the OE upper arm location. Here you can see the upper arm as the rear is being fastened in place. Like the lower arms, the uppers feature greasable bushings. 8. Chrysler buried the OE rear passenger-side upper control-arm bolt in such a way that it has to be cut out. We made two cuts to the bolt-the head and the body-to remove it. The only way around this is to remove the exhaust system. Fortunately, BDS includes a new bolt and it feeds in from the other direction and solves the problem. PhotosView Slideshow 9. The OE spring isolators and stud rings are used on top of the new BDS springs. The kit also includes new longer BDS 9500 gas shocks. 10. A track-bar relocation bracket is included to properly center the axle under the vehicle. It is fastened to the OE track-bar frame mount and to the track bar via 9/16-inch bolts. 11. Extended bumpstops and sway-bar end links (shown) are included to maintain the OE handling characteristics. 12. The OE lower control-arm frame brackets are removed from the vehicle, and the bare metal is painted to prevent corrosion. 13. Here's the front suspension in finished form. BDS says that this setup creates 6 inches of total lift. 14. BDS says that the new rear leaf springs included in our kit generate 5 inches of lift. Installation is straightforward, though it's important to note that the Ram 2500/Mega Cab came with three different-diameter axletubes so you need to know which one you have so BDS can send the correct U-bolts. 15. Like the front, the rear suspension gets new extended-length BDS 9500 gas shocks. 16. Before the install, the Mega Cab traveled 47 inches up our 20-degree RTI ramp. 17. After the BDS install, it climbed 52 inches up our ramp-a gain of 5 inches.

Longer lower control arms create less caster change through the entire range of wheel travel when compared to the stock setup. Among other things, this creates a more solid feel in the steering wheel and better off-highway characteristics. Translation: It ain't a handful to drive. As a matter of fact, the owner of this Mega Cab drove the truck from Illinois to Colorado and back immediately following the install and reported no annoying quirks or problems throughout the trip.

The kit is advertised to fit up to 36x12.50 tires on a 17x9 wheel with 5 inches of backspacing. The owner of this rig chose 37x12.50-18 tires on 18x9 wheels. It's been 'wheeled during an elk-hunting foray and no rubbing was reported, though we expect there might be rubbing in the front in instances where the wheels travel through a complete cycle.

If we were going to do one thing different, we would probably upgrade to the dual front-shock option to offset the heavy front bumper and winch we installed. It's a tad soft for our taste, but that's our preference. Ultimately, we (and the owner) are very pleased with this kit's ease of installation, quality of components, and on- and off-highway performance.
