6 Best Steel Shim Sets For Leveling Vehicle Lifts For Shops

A concrete floor in a farm shop is rarely as level as it appears, often sloping intentionally for drainage or settling unevenly over years of heavy machinery traffic. Ignoring a slight tilt when installing a vehicle lift compromises structural integrity and places dangerous, uneven stress on the hydraulic system. Proper shimming turns a potential safety hazard into a stable, reliable foundation for tractor maintenance and equipment repairs.

Precision Brand C-1018 Steel Shim Stock Kit

The Precision Brand C-1018 kit offers an unparalleled range of thicknesses, which is vital when dealing with floor variances that change by the fraction of an inch. High-quality carbon steel ensures these shims maintain their shape under the immense vertical loads of heavy implements and chassis-heavy trucks.

This set is the industry standard for precision. Use this kit if the floor variance is highly irregular, requiring layered adjustments to achieve perfect plumb. It remains the top choice for those who prioritize exact tolerances over speed of installation.

Tusco Products Slotted Shim Set: Best Value

Tusco Products provides a bulk, slotted design that allows for quick placement without the need to fully remove anchor bolts. For a busy shop environment, the ability to slide these into place significantly reduces downtime during the initial setup phase.

These shims balance cost-effectiveness with structural reliability. Opt for this set if the shop floor is relatively consistent but needs minor adjustments. It is the most pragmatic investment for owners who need to level multiple lifts without breaking the budget.

Titan Industrial U-Shims: Easiest to Install

Titan Industrial U-Shims feature a distinct shape that grips the anchor bolt firmly, preventing the shim from shifting during the final torqueing process. Their heavy-duty gauge steel handles significant compression without deforming or bowing under load.

If speed and simplicity are the primary goals, these U-shims are the best candidate. The installation process is straightforward, requiring minimal tools to slide them into the gap. This is the ideal solution for a solo operator who lacks a second pair of hands for leveling adjustments.

SteelShims USA Kit: Top Corrosion Resistance

Environment is a major factor in farm shops, where humidity and chemicals often lead to rust in hard-to-reach areas like the base of a lift. SteelShims USA utilizes high-grade, corrosion-resistant materials that prevent the metal from flaking or thinning over time.

Selecting a corrosion-resistant shim is a proactive measure against structural failure in damp or high-moisture environments. Use these if the shop floor is prone to standing water or seasonal dampness. This kit ensures the shim maintains its integrity for years, preventing the need to re-level the lift due to material decay.

Magna-Lock 280-Piece Assortment: Pro Choice

The Magna-Lock assortment is a comprehensive solution, providing a massive variety of sizes and shapes to handle any leveling emergency. Having 280 pieces on hand means there is no need to pause a job because a specific thickness is missing.

This is the ultimate professional-grade kit for shops that service various types of equipment. While the initial investment is higher, the sheer versatility makes it indispensable for large-scale operations. It is the correct choice for anyone who refuses to compromise on having the exact part on hand.

Pro-Grade Multi-Shim Pack: For Uneven Floors

When dealing with drastically uneven concrete, the Pro-Grade Multi-Shim Pack offers thicker options that fill larger gaps without requiring an excessive number of individual sheets. Stacking too many thin shims can create a “mushy” base that is prone to slippage, but these thicker units provide a solid foundation.

If the foundation has significant dips or gouges, these thicker shims provide the necessary support. They are designed to withstand heavy vibration, ensuring the lift remains steady while working on engines or transmission swaps. This set is essential for older barns or shops with poured foundations that have settled over time.

How to Choose the Right Shim Material and Size

Steel is the only acceptable material for leveling vehicle lifts. Avoid plastic or wood shims at all costs, as these materials compress, crack, or rot under the thousands of pounds of pressure exerted by a lift.

Match the shim surface area to the footprint of the lift base. A shim that is too small will cause point loading, which cracks concrete over time. Aim for a shim that covers at least 75% of the base plate surface area to distribute the load evenly across the floor.

A Guide to Properly Shimming Your Vehicle Lift

Start by using a high-precision digital level on all four posts before tightening the anchor bolts. Once the high spot is identified, determine the required thickness by sliding shims underneath the low posts until the bubble centers perfectly.

Always tighten your anchor bolts in a cross-pattern to ensure even compression across the base. Check the level again after the final torque sequence, as the base plate can shift slightly during the process. Keep a log of how many shims were used at each location for future reference.

Safety First: Critical Shimming Do’s and Don’ts

Do check the manufacturer’s specifications regarding the maximum allowable shim height before installation. Excessive shimming can put unnecessary stress on anchor bolts, reducing their pull-out strength in the concrete.

Don’t use makeshift materials like washers or scrap metal. These items often have uneven surfaces that create unstable contact points. Always ensure that the shims used are rated for structural loads and are of uniform thickness across the entire surface.

FAQ: Answering Your Top Lift Shimming Questions

Can I stack thin shims to reach a specific height? Yes, but keep the stack to a minimum—usually no more than three or four pieces—to maintain stability.

How often should I check my lift level? Inspect the levels annually or whenever there is noticeable movement or unusual noise during operation.

Does the shim need to be the same size as the base plate? It should be large enough to provide full support, but it does not need to match the footprint exactly; focus on providing a stable platform for the load-bearing columns.

A level lift is the backbone of a safe farm shop. By choosing the right steel shims and following rigorous installation practices, you create a stable environment that protects both your valuable equipment and the operator. Invest in high-quality materials now to avoid the significant costs and risks of structural failure later.
