2004.5-2007 Dodge 5.9L Cummins Shocks

Shocks on the 2004.5-2007 RAM 5.9L Cummins

The third-gen Ram 2500/3500 4x4 uses a link-coil solid front axle: upper and lower trailing arms, coil springs, and a two-eye track bar that locates the axle side to side. 2WD trucks run coils up front as well. The rear is a solid axle on leaf springs. The springs carry the weight; the shocks control how fast the truck moves on them. With a 5.9L Cummins that weighs roughly 1,150 lb dry and dressed sitting up front, the front shocks have real work to do.

What shocks can and can't fix

Shocks get blamed for problems they don't cause. Rear sag under a fifth-wheel or gooseneck is the common hauling complaint on this generation, and that is a spring problem. The usual answer is load support such as air helper springs, with Bilstein shocks on the same upgrade list. Death wobble is the other one. On these solid-axle trucks it usually traces to play in the track bar, tie rods, ball joints or steering box, and worn track bar bushings and frame-end joints are a common source. Diagnose before you buy: with the truck on the ground, have someone saw the steering wheel back and forth while you watch the track bar for movement.

Stock replacement vs. upgrade

Every shock here is a vehicle-specific part, listed by position and drivetrain. If the truck sits at factory height and you just want the ride back, match the factory position and drivetrain and you're done. If you're building a heavier-duty setup, Bilstein shocks also turn up in documented third-gen suspension builds, including a 2004 truck fitted with multi-rate coils, progressive rear leaves and an adjustable track bar. If your truck has been leveled or lifted, tell us how much before you order so the shock length matches.

What we carry

Bilstein makes up most of this page. The B8 5100 Series is listed for 4WD front and rear positions, and the B6 4600 Series covers 4WD front and rear plus a 2WD rear. Several of these part numbers also fit later 6.7L Cummins trucks, and a few cross to Duramax or Power Stroke applications, which is why the titles run long. Fleece Performance Engineering rounds it out with its FPE-LPSM low profile shock mounts, listed for 1994-2012 5.9L and 6.7L Cummins trucks.

Fitment notes

Pick position first, then drivetrain. Front and rear shocks are different part numbers, and 2WD and 4WD trucks use different rears. Read each title closely, because the years, engines and drivetrains vary from one part number to the next. On a 2007, confirm you have the 5.9L and not the 6.7L that replaced it for trucks built after January 1, 2007; many of these shocks list both engines, but the rest of your parts list may not. The Power Wagon is a Hemi gas truck, not a Cummins, so it doesn't belong here. When in doubt, verify by VIN.

Frequently asked questions

Will new shocks cure death wobble on my 5.9L Ram?

Usually not by themselves. Death wobble on these trucks generally comes from play in the track bar, tie rods, ball joints or steering box. Owners chasing it often replace the track bar and steering damper together, but do the on-the-ground saw-the-wheel test first so you fix the part that is actually loose.

My truck squats with a fifth-wheel hitched. Will stiffer shocks fix it?

No. Rear sag under fifth-wheel and gooseneck loads is the common hauling complaint on this generation, and it's a spring issue. Air helper springs are the usual fix for sag; shocks handle body control once the ride height is right.

Do these shocks fit a 2002 or older Ram?

Some do. Several part numbers here list 1994-2013 coverage, while others start at 2003, so the listing title is the authority. Don't assume the rest of the front end crosses over: the 2003-2009 axle, track bar and ball-joint design is different from the 1994-2002 trucks.
