2007.5-2009 Dodge 6.7L Cummins Traction Bars

Traction bars on the 2007.5-2009 Ram 6.7L Cummins

A 4x4 Cummins Ram of these years uses a coil-sprung 4-link front and a leaf-spring rear, the setup shared by 2003-2012 heavy-duty Rams. A traction bar runs from a bracket at the rear axle forward to a mount on the frame and limits how far the axle can rotate on the leaf springs under torque. Other rear upgrades documented for these trucks are long-travel leaf springs or overload changes for ride, and air bags for heavy towing.

Kit or universal bars

A truck-specific kit, like the BD Diesel or BDS kits here, is listed for specific years and models, so fitment is spelled out in the title. Universal bars are sold by length, 60-inch or 68-inch, and WCFab sells the bars alone, as Dodge/Ford kits, and with a separate brackets and hardware install kit. Measure your truck before you choose a length, and read each listing for what is in the box. If the truck is lifted more than 3 inches, plan driveline work along with the bars, since lifts that tall on 2003-2009 Rams may need pinion angle correction.

What we carry

Fitment notes

Read the years in each title. The BDS2305 Recoil kit is listed from 2009, so 2007.5 and 2008 owners should call before ordering it. The BDS fixed bars are listed for 2500 4WD trucks, and the BD Diesel kit excludes trucks with air suspension. Rear spring packs differ between the 2500, 3500 and dually, and options change weight, so measure your own truck. Suspension parts on these Rams are a 2003-2009 chassis fitment, not an engine fitment. When in doubt, verify by VIN.

Frequently asked questions

Do traction bars fit both the Ram 2500 and 3500?

Some do. The BD Diesel 1032130 kit lists 2500 and 3500 trucks without air suspension, while the BDS fixed bars list 2500 4WD trucks. Rear spring packs differ between the 2500, 3500 and dually, so check the listing and measure your truck.

Should I buy a 60-inch or 68-inch universal bar?

Measure first. The length you need depends on where the axle bracket and the frame mount land on your truck. WCFab sells both lengths as bare bars and as Dodge/Ford kits, plus a separate bracket and hardware kit. Call us if you want a second opinion on the measurement.

Can I replace worn bushings or heims instead of the whole bar?

If your bars use them, yes. The WCFab WCF207-26 bushings and heims are on this page as replacement parts. Check that they match the bar you have, and call us if you are not sure which brand is on your truck.
