6 Best Alignment Shims For Correcting Camber On Lifted Vans

Lifting a van for better ground clearance or a more aggressive stance inevitably alters the factory suspension geometry. Without correcting that newfound camber, the tires will scrub unevenly and compromise handling on winding mountain roads. Investing in the right alignment shims ensures the van tracks straight and maintains safety, whether traversing forest service roads or cruising on the interstate.

SPC 23229 Camber Bushing: Best Overall

When it comes to versatility and ease of adjustment, the SPC 23229 remains the gold standard for most van conversions. These bushings offer a wide range of adjustment, allowing for the fine-tuning required when a suspension lift shifts the axle angle significantly. Their design is robust enough to handle the extra weight of a fully loaded camper interior without failing under the constant stress of the road.

Because they are widely available and supported by extensive technical documentation, finding a shop willing to install them is never a hurdle. They function as a “set and forget” solution, provided the initial installation is dialed in correctly. For those who want a reliable, proven path to corrected alignment, these are the clear choice.

Moog K7254 Bushing: Most Heavy-Duty

If the build involves heavy-duty bumpers, oversized tires, and constant off-road abuse, the Moog K7254 is the preferred candidate. Moog has a long-standing reputation for engineering components that exceed original equipment specifications in terms of durability. These bushings are built to withstand high-impact scenarios that would cause lighter-weight alternatives to deform or loosen over time.

They are inherently stiffer, meaning they hold their position firmly even under the immense torque of a heavy, lifted van. While they may be slightly more challenging to source or install, the trade-off is superior longevity in demanding environments. For the serious overlander who prioritizes mechanical integrity above all else, these are the heavy hitters.

Ingalls 594 Bushing Kit: Easiest Install

Time is a premium when modifying a vehicle, and the Ingalls 594 kit excels in minimizing downtime during the installation process. The design features a user-friendly indexing system that allows for quicker setup compared to traditional, more complex bushing styles. This efficiency is a massive benefit for those performing the work in a driveway or a temporary workspace.

Despite the focus on installation speed, there is no sacrifice in the actual correction capability. The kit effectively addresses moderate lift heights, bringing camber back into the factory-recommended tolerance window with ease. If the primary goal is a smooth, efficient DIY project, this kit offers the most logical path to success.

Specialty Products 23228: Ford E-Series Pick

The Ford E-Series platform requires specific geometry due to its twin I-beam front suspension, making the Specialty Products 23228 the definitive choice for these models. These bushings are engineered with the unique pivot points of the E-Series in mind, ensuring the alignment remains stable even after the suspension has been modified. Using generic parts on an E-Series often leads to recurring alignment issues, but this unit integrates perfectly.

They are highly regarded for their precision, which is critical for steering feedback and tire longevity on these heavier chassis. Installation is straightforward for those familiar with Ford suspension work, making them a staple in the van-building community. Owners of E-Series vans should look no further; this is the component engineered specifically for that architecture.

Firestone Ride-Rite Shim Kit: Best for Airbags

Integrating an airbag suspension system adds a layer of complexity to alignment because of the constant fluctuations in ride height. The Firestone Ride-Rite shim kit is specifically designed to work in conjunction with air-assisted setups, providing the adjustability needed to account for varying inflation levels. They provide the necessary stability to prevent the “wandering” steering common in air-suspended vehicles that have not been properly shimmed.

These shims are built to maintain structural integrity while subjected to the dynamic load changes associated with air systems. They are the ideal solution for those who tow frequently or carry varying cargo loads that require regular pressure adjustments. If the van uses an airbag system, this is the safest and most effective way to keep the geometry in check.

NAPA Chassis Camber Kit: Top Budget Choice

Budget constraints are a reality in every build, and the NAPA Chassis camber kit provides a reliable solution without the premium price tag. While it may not feature the advanced materials of specialized, high-end bushings, it meets the essential requirements for restoring proper alignment after a standard lift. It is a no-frills, functional component that gets the job done for the vast majority of drivers.

Availability is a major advantage here, as NAPA locations are pervasive, making it easy to replace parts mid-journey if necessary. These kits are suitable for daily drivers and weekend campers that don’t see extreme off-road conditions. For the builder on a strict budget, these shims represent excellent value and consistent performance.

Do You Even Need Camber Shims? A Quick Test

Before purchasing parts, confirm that the alignment is actually outside of the factory specification. A quick and effective test involves inspecting the “wear pattern” on the front tires; look for accelerated wear on the inner or outer edges compared to the center treads. If one side is balding significantly faster than the other, the camber is likely misaligned due to the lift.

Another way to tell is by observing the steering behavior on a flat, straight road. If the van consistently pulls to one side or feels “loose” at highway speeds, it is an indicator that the geometry is out of whack. Do not rely solely on visual estimation, as the human eye rarely catches subtle but damaging alignment errors.

How to Measure Your Van’s Camber at Home

Measuring camber at home requires a simple magnetic angle finder and a flat, level surface. Park the van on a level garage floor and ensure the tires are at the correct pressure before starting. Place the angle finder against the wheel rim, ensuring it is vertical, and record the reading in degrees.

A positive camber reading means the top of the wheel tilts outward, while a negative reading means it tilts inward. Compare this measurement to the manufacturer’s specifications listed in the service manual. If the difference is significant, the need for shims is confirmed, and the measurements will help determine which degree of adjustment is required.

Installing Your New Camber Bushings: A Guide

Installation typically requires the use of a ball joint press to remove the existing factory bushing and seat the new one. Always ensure the front end is securely supported on jack stands—never rely on a floor jack alone during this process. Take note of the orientation of the old bushing, as the new one must be indexed precisely to match the desired alignment change.

Once the new bushing is pressed in, tighten all hardware to the factory-specified torque settings to prevent shifting. Be mindful that even a small error in the orientation of the offset bushing can lead to drastic alignment changes. Accuracy during the seating process is the most important factor in a successful installation.

Finding a Shop for a Post-Install Alignment

Even after a successful DIY bushing install, a professional four-wheel alignment is non-negotiable. Modern alignment machines use lasers to measure angles that cannot be accounted for by manual tools, ensuring the toe, caster, and camber are perfectly balanced. Look for an alignment shop that specializes in trucks or large vans, as standard passenger car shops may lack the equipment to lift or secure heavier vehicles.

When dropping off the van, provide the technician with the specific alignment specifications for the lifted height, rather than asking them to use standard factory settings. A transparent conversation about the lift kit ensures the technician isn’t confused by the non-standard geometry. Professional verification is the final step in protecting the investment in tires and suspension.

Properly addressing camber issues after a lift is not just about tire longevity; it is a fundamental aspect of safe vehicle handling on the road. By selecting the right hardware and verifying the alignment with professional equipment, a van remains a stable and predictable platform for every journey. Consistent maintenance of these components will keep the rig tracking straight for years to come.
