Volvo S80 Alignment Caster and Camber Kit (1999-2010)
Solve persistent tire wear and handling problems on your S80 by adding front-end alignment adjustability.
- This kit is an upgrade, not a direct replacement, that adds front camber/caster adjustability the S80 lacks from the factory.
- It is essential for correcting uneven inner tire wear, especially on lowered cars or those with worn suspension.
- Installation of the bolts must be followed by a professional four-wheel alignment to be effective.
- Mevotech is a common aftermarket brand for this part, providing a functional and affordable solution.
Is Your S80 Wearing Out Tires Unevenly?
If you're noticing the inside edge of your front tires wearing out much faster than the rest of the tread, you're not alone. This is a common issue for 1999-2010 Volvo S80 owners. The root cause is often an incorrect camber angle that cannot be corrected with the factory suspension hardware. Your alignment technician can set the "toe" perfectly, but if the camber is out of specification, your tires will continue to wear unevenly, and your car might pull to one side.
What is Caster and Camber?
Think of your car's wheels from the front. Camber is the top-to-bottom tilt of the wheels. Too much inward tilt (negative camber) wears the inside of the tire, while too much outward tilt (positive camber) wears the outside. Caster is the forward or backward tilt of the steering axis. Correct caster is important for steering stability and the steering wheel's ability to return to center after a turn.
Factory Suspension Has No Adjustment
The 1999-2010 Volvo S80 was designed with a fixed front suspension geometry for camber and caster. This means as suspension parts like control arms and bushings wear over time, or if the vehicle's ride height is changed (e.g., with lowering springs), the alignment angles can fall out of spec with no way to adjust them back. An aftermarket caster/camber kit is the only way to add this much-needed adjustability.
Choosing the Right Aftermarket Kit
For the 1999-2010 S80, the solution is an aftermarket alignment kit, often called a "camber bolt kit." These kits typically include one or two eccentric bolts per side. An eccentric bolt has a lobe or cam on it that pushes the strut and steering knuckle assembly in or out as it's turned, allowing for precise camber and caster changes.
Mevotech is a widely available aftermarket brand that produces alignment kits for the S80. They are generally considered a decent quality aftermarket option, often positioned as a problem-solver for common vehicle issues. For a part like this, which adds a function the original part lacked, brand reputation is less about being "better than OEM" and more about providing a reliable solution. Mevotech kits are known to fit correctly and get the job done.
Installation Requires an Alignment
While swapping the bolts themselves is straightforward, the adjustment process is not a simple DIY task. The kit should be installed by a qualified mechanic as part of a professional four-wheel alignment service. The technician will use an alignment rack to measure the angles in real-time while turning the bolts to bring the suspension back into Volvo's specifications.
Known Issues, Recalls, and TSBs
While there are no specific recalls or Technical Service Bulletins (TSBs) for the non-adjustable factory bolts, there was a safety recall for some 2004 S80 models (Recall 133). This recall concerned a ball joint nut on the front control arm that could loosen, causing steering alignment issues and noise. This highlights the importance of keeping all suspension components in good condition, as a failure in one part can affect alignment and safety. Other recalls for this generation S80 primarily concern airbags and engine software.

Frequently Asked Questions
Do I need this kit if my S80's suspension is stock?
You might. Even with a stock, unmodified suspension, normal wear and tear on bushings, ball joints, and springs can cause the alignment to fall out of specification. If an alignment shop tells you they can't correct your camber, this kit is the solution.
Is this kit for the front or rear suspension?
This specific type of bolt kit is for the front suspension, where the strut connects to the steering knuckle. Some all-wheel-drive models may also have issues with rear camber, which requires a different solution, such as offset bushings.
Will this fix my car's pulling or drifting?
It can. Pulling is often caused by uneven alignment angles, including camber and caster. If your car pulls and an alignment without this kit doesn't fix it, installing and properly adjusting these bolts is the next logical step. However, pulling can also be caused by tire issues or a sticking brake caliper.
Can I install this kit myself?
You can physically install the bolts, but you cannot complete the job without a professional alignment. The bolts must be adjusted using an alignment machine to achieve the correct angles. Attempting to guess the adjustment will result in poor handling and accelerated tire wear.
