NEOVIRE 55398938AC Front Sway Bar & K80894 End Link Kit for Ram 1500 4WD

The NEOVIRE 55398938AC Front Suspension Stabilizer Bar and K80894 End Link Kit is a complete front sway bar replacement package for select 2009–2022 Dodge Ram and Ram 1500 4WD trucks.

The kit combines a solid front stabilizer bar with replacement end links and polyurethane mounting bushings, making it suitable for repairing worn, damaged or corroded factory stabilizer components.

What’s Included?

The NEOVIRE kit provides the major components required to restore the front stabilizer system, including:

  • Front suspension stabilizer/sway bar
  • Two front sway bar end links
  • Polyurethane sway bar mounting bushings
  • Associated mounting components

Replacing the bar, links and bushings simultaneously can make sense on a higher-mileage truck where multiple stabilizer components have deteriorated.

What Does the Ram 1500 Front Sway Bar Do?

The front stabilizer bar connects the left and right sides of the suspension.

When the truck corners, the outside suspension compresses while the inside suspension unloads.

This twists the sway bar.

The bar resists that twisting motion, helping reduce excessive body roll and maintain more predictable chassis behavior.

A properly functioning stabilizer system contributes to:

  • Body-roll control
  • Cornering stability
  • Steering response
  • Highway stability
  • Transitional handling
  • Predictable suspension behavior

Symptoms of Worn Sway Bar Components

Potential symptoms include:

  • Clunking over bumps
  • Knocking from the front suspension
  • Excessive body roll
  • Loose handling
  • Poor transitional response
  • Cracked mounting bushings
  • Loose sway bar links
  • Corroded stabilizer components

A damaged or bent stabilizer bar may also require complete replacement.

Solid Alloy Construction

The NEOVIRE replacement sway bar uses high-strength solid alloy construction intended to resist deformation under normal suspension loads.

That’s important because the stabilizer bar repeatedly twists as the suspension moves independently from side to side.

The objective is to maintain consistent torsional behavior without bending or permanently deforming.

Corrosion-Resistant Coating

The stabilizer bar receives a protective coating designed to reduce corrosion.

Underbody suspension components are constantly exposed to:

  • Water
  • Dirt
  • Mud
  • Road salt
  • Sand
  • Gravel
  • Temperature changes

Corrosion resistance becomes especially important on trucks used in harsh climates or frequently driven off pavement.

Polyurethane Bushings

The kit uses polyurethane sway bar mounting bushings.

These bushings secure the stabilizer bar to the chassis while allowing it to rotate as the suspension moves.

Compared with heavily worn factory rubber, fresh polyurethane bushings can provide more consistent bar positioning.

Potential advantages include:

  • Reduced unwanted movement
  • More direct sway-bar response
  • Improved durability
  • Better resistance to deformation

K80894 Front End Links

The included sway bar end links cross-reference K80894 and several Ram OE numbers.

The links transfer suspension movement into the stabilizer bar.

When they develop excessive play, drivers may notice:

  • Clunking
  • Knocking
  • Loose suspension feel
  • Reduced sway-bar effectiveness

Replacing the links while replacing the sway bar eliminates another major wear point.

Can This Kit Fix Front Suspension Clunking?

Yes, if the clunk is actually coming from worn sway bar links or bushings.

However, front suspension noises can also originate from:

  • Ball joints
  • Control arm bushings
  • Tie rods
  • Wheel bearings
  • Shocks
  • Steering components

Inspect the suspension before replacing components.

The parts cannon remains extremely effective at converting money into boxes without necessarily fixing the noise.

2009–2010 Dodge Ram 1500 Fitment

The earliest applications are:

2009 Dodge Ram 1500 4WD

2010 Dodge Ram 1500 4WD

These trucks were sold under the Dodge Ram brand before Ram became a standalone marque.

2011–2018 Ram 1500 Fitment

The primary application is:

2011–2018 Ram 1500 4WD

These trucks use the DS-generation platform associated with the 55398938AC stabilizer bar.

2019–2022 Ram 1500 Classic Fitment

The previous-generation DS truck continued after 2018 as the:

2019–2022 Ram 1500 Classic 4WD

This distinction should be clearly stated in any online catalog.

Correct

2019–2022 Ram 1500 Classic 4WD

Potentially misleading

2019–2022 Ram 1500

That second description can lead DT-generation owners to believe the component fits their truck.

Does a New Sway Bar Reduce Tire Wear?

A properly functioning suspension can contribute to more consistent tire loading, but a sway bar shouldn’t be marketed as a direct cure for tire wear.

Abnormal tire wear is more commonly related to:

  • Incorrect alignment
  • Worn ball joints
  • Worn control arm bushings
  • Tire pressure
  • Damaged suspension components

Replacing worn stabilizer components can restore handling, but it doesn’t replace proper alignment and suspension diagnosis.

Installation

General installation includes:

  1. Park the truck on a level surface.
  2. Safely raise and support it.
  3. Inspect the front suspension.
  4. Disconnect both front sway bar end links.
  5. Support the original stabilizer bar.
  6. Remove the sway bar mounting brackets.
  7. Remove the original stabilizer bar.
  8. Compare the original and replacement bars.
  9. Install the supplied polyurethane bushings.
  10. Position the NEOVIRE sway bar.
  11. Install the mounting brackets.
  12. Install the K80894-style end links.
  13. Torque hardware to factory specifications.
  14. Check steering and suspension clearance.
  15. Road-test.
  16. Reinspect all mounting hardware.

Always use the appropriate Ram factory service information and torque specifications.

Does Installation Require an Alignment?

Normally, no.

The sway bar and links don’t directly determine:

  • Camber
  • Caster
  • Toe

Replacing these components generally doesn’t require an alignment unless other suspension parts are disturbed.
