Because this list contains numbers for both the sway bar and associated end links, verify the original vehicle components before ordering.
What’s Included?
The Dasbecan kit contains:
- 1 × Front stabilizer/sway bar
- 2 × Sway bar mounting bushings
- 2 × Bushing retainers
- 4 × Hex-head mounting screws
- 2 × Front sway bar end links
This makes the kit suitable for a more complete front stabilizer-system overhaul rather than replacing only one worn component.
What Does the Ram 1500 Front Sway Bar Do?
The front sway bar connects the left and right sides of the front suspension.
During cornering, the outside suspension compresses while the inside suspension unloads.
This difference in suspension movement twists the sway bar.
The bar resists that twisting motion and helps control excessive chassis roll.
A properly functioning stabilizer system contributes to:
- Reduced body roll
- More predictable cornering
- Better transitional response
- Improved highway stability
- More controlled lane changes
Symptoms of Worn Ram 1500 Sway Bar Components
Common symptoms include:
- Clunking over bumps
- Knocking from the front suspension
- Excessive body roll
- Loose handling
- Reduced steering response
- Cracked mounting bushings
- Worn sway bar links
- Corroded mounting hardware
If the sway bar itself is damaged, bent or heavily corroded, replacing the complete assembly may make more sense than servicing the links and bushings individually.
K80894 Sway Bar End Links
The included end links replace applications associated with K80894 and related OE numbers such as:
5170290AB
5170290AC
5170290AD
End links connect the stabilizer bar to the suspension.
When these components wear, they can develop excessive movement and produce a distinctive clunking or knocking sound over uneven pavement.
Replacement Bushings
The kit also includes two sway-bar mounting bushings.
These bushings secure the center section of the stabilizer bar to the chassis while allowing the bar to rotate as the suspension moves.
Worn bushings can allow excessive bar movement, potentially causing:
- Clunking
- Squeaking
- Reduced sway-bar response
- Poor stabilizer-bar positioning
Replacing the bushings at the same time as the bar eliminates another common wear point.
Steel Construction
The Dasbecan sway bar uses steel construction intended to withstand the repeated torsional loads generated by suspension movement.
The components are also designed to resist normal corrosion and wear associated with underbody exposure.
That’s important on trucks exposed to:
- Water
- Road salt
- Dirt
- Mud
- Gravel
- Off-road conditions
2009–2010 Dodge Ram 1500
The first applications are:
2009 Dodge Ram 1500 4WD
2010 Dodge Ram 1500 4WD
These trucks were still officially sold under the Dodge Ram name.
2011–2018 Ram 1500
Fitment continues with:
2011–2018 Ram 1500 4WD
These DS-generation trucks represent the largest application range for the 55398938AC sway bar assembly.
2019–2022 Ram 1500 Classic
When Ram introduced the new DT-generation truck, production of the previous DS platform continued under the Ram 1500 Classic name.
Therefore, the later application is:
2019–2022 Ram 1500 Classic 4WD
Not simply:
2019–2022 Ram 1500
That’s an important distinction for an online parts catalog.
Daily Driving
Replacing deteriorated stabilizer components can help restore the truck’s original suspension response during normal driving.
Drivers may notice improved control during:
- Highway ramps
- Lane changes
- Curving roads
- Emergency maneuvers
- Uneven pavement
This is primarily a replacement/restoration component rather than an aggressive aftermarket handling upgrade.
Towing and Hauling
A properly functioning front suspension is important when towing or carrying cargo.
The sway bar contributes to body-roll control, but replacing it does not increase the manufacturer’s payload or towing capacity.
Always remain within the truck’s rated limits.
Off-Road Driving
Four-wheel-drive Ram 1500s may experience substantial suspension articulation off-road.
After aggressive off-road use, inspect:
- Sway bar
- End links
- Bushings
- Retainers
- Mounting hardware
Look for impact damage, bending or loosened components.
Installation
General installation involves:
- Park the truck on a level surface.
- Safely raise and support the vehicle.
- Inspect the complete front suspension.
- Disconnect both sway bar end links.
- Support the original stabilizer bar.
- Remove the sway bar mounting retainers.
- Remove the original sway bar.
- Compare the replacement components.
- Install the supplied bushings.
- Position the Dasbecan stabilizer bar.
- Install the retainers and mounting hardware.
- Install the K80894-style end links.
- Torque hardware to factory specifications.
- Verify suspension and steering clearance.
- Road-test the truck.
- Reinspect all hardware.
Follow factory service procedures and torque specifications for the specific model year.
Does Installation Require an Alignment?
Normally, no.
The front sway bar and end links don’t directly establish:
- Camber
- Caster
- Toe
Replacing these components generally doesn’t require a wheel alignment unless other suspension components are disturbed.
Inspect the Rest of the Front Suspension
While installing the sway bar, inspect:
- Upper control arms
- Lower control arms
- Ball joints
- Inner and outer tie rods
- Front shocks
- Wheel bearings
- CV boots
- Steering components
If the truck has substantial mileage, more than one component may be responsible for front suspension noise.

Recommended ProStreetOnline Product Title
Dasbecan 55398938AC Front Sway Bar & K80894 End Links – 2009-2022 Ram 1500 Classic 4WD
For maximum catalog accuracy, I’d use:
Dasbecan 55398938AC Front Sway Bar Kit – 2009-2018 Ram 1500 / 2019-2022 Ram 1500 Classic 4WD
That prevents the product from accidentally being presented as compatible with the newer DT-generation Ram.
