Shims for Damping Control

You use a shim inside a shock absorber to control how fluid moves through it. This process is governed by fluid dynamics. A shim stack changes the flow area for the oil, which directly impacts the pressure needed to move it. This change in pressure creates the damping force you feel.

Different shim stack designs allow you to fine-tune this force. You can use various custom precision shims to achieve specific results for your suspension.

• Simple Tapered Stacks: These custom precision shims create a damping force that softens at very high speeds.
• Crossover Stacks: This setup uses a specific shim to separate the stack, allowing you to soften low-speed damping for a more comfortable ride over small bumps.
• Preloaded Stacks: Using a ring shim, you can preload the stack. This increases low-speed damping for better control, making it a popular choice for performance suspension tuning.

The thickness and diameter of each precision shim are critical. These dimensions determine the stiffness of the stack and how much the suspension resists movement, giving you control over the entire damping curve. Every precision shim contributes to the final feel of the suspension.

Shims for Alignment Correction

You can also use a shim to adjust the physical alignment of suspension components. These adjustable shims are placed between parts like the axle and the leaf spring to change critical angles. Correcting these angles is essential for tire wear, vehicle stability, and overall handling. A single precision shim can solve major issues.

For example, you might use a precision shim to fix your vehicle’s camber, caster, or pinion angle. These custom precision shims come in various materials and degrees.

When selecting a precision shim, material matters. Max provides custom precision shims made from superior materials for lasting performance.

Pro Tip: For alignment shims, material quality often follows this hierarchy:

Practical Guide to Using Shim Suspension Kits

You can use shim suspension kits to transform your vehicle’s handling and ride quality. These kits provide the precision shims needed for detailed adjustments. This guide shows you how to use shim suspension kits for three common tasks. You can tune your shocks, correct alignment, and eliminate driveline vibrations. Each task requires a different approach and a specific type of shim.

Tuning Shocks for Better Performance

You can achieve significant performance upgrades by tuning your shock absorbers. This process involves changing the internal shim stack to alter damping forces. Using shim suspension kits gives you the precision shims necessary for this job. For example, off-road racers often use stacked spring setups and specific shim stacks to maintain stability on rough terrain. They tune for low, medium, and high-speed damping to handle different impacts. Asphalt racers might use a different shim setup to optimize grip on smooth surfaces.

To change the shim stack, you must first disassemble the shock. Here is a step-by-step guide for a typical monotube shock:

1. Secure the shock in a vise with the body facing up.
2. Release the nitrogen gas by removing the Hyperscrew.
3. Flip the shock in the vise so the body faces down.
4. Remove the snap ring near the shaft to free the gland retaining ring.
5. Carefully remove the Hyperscrew in the gland. Be ready for some oil spray.
6. Push the gland into the shock body about half an inch and remove the gland snap ring.
7. Pull the piston rod assembly out of the shock body.
8. Now you can access the shim stack to make changes. You can replace the valving with new precision shims from your shim suspension kits.

Safety First! ⚠️ Always release all gas pressure from a shock absorber before disassembly. A pressurized shock can be extremely dangerous.

Each precision shim you add or remove changes how the suspension reacts. Thicker precision shims create more damping, while thinner ones soften the ride. Using shim suspension kits allows you to experiment with different combinations. This is one of the most effective performance upgrades for your suspension. A single shim can make a noticeable difference in your vehicle’s handling.

Correcting Camber and Caster Angles

You can use shim suspension kits to correct your vehicle’s wheel alignment. Poor alignment is a common problem caused by hitting potholes or overloading your vehicle. It leads to poor handling and premature tire wear. A precision shim can fix these issues. The most obvious sign of bad alignment is uneven tire wear.

• Wear on the outside edge of your tire often means you have too much positive camber.
• Wear on the inside edge of your tire suggests too much negative camber.

These wear patterns happen because the tire scrubs against the road instead of rolling smoothly. You can use adjustable shims to fix this.

To correct these issues, you place a shim between suspension components. For example, you can insert a precision shim between the control arm and the frame. This changes the angle of the wheel. The degree of the shim determines the amount of correction. Using shim suspension kits gives you a range of precision shims to choose from. This helps you dial in the perfect alignment for your suspension. A small shim can restore your vehicle’s stability and save you money on tires. Every precision shim in your shim suspension kits is a tool for better driving.

Adjusting Pinion Angle to Stop Vibration

You might feel a vibration through the floor of your car, especially during acceleration. This is often caused by an incorrect pinion angle. The pinion angle is the relationship between your driveshaft and your rear axle. Using shim suspension kits, you can place a precision shim between the axle and the leaf spring to correct this angle. This is a critical adjustment for any rear-wheel-drive vehicle.

To find the right shim, you first need to measure your current angles. You can use a digital angle finder or a smartphone app.

1. Place your vehicle on a level surface with its full weight on the suspension.
2. Measure the angle of your transmission or engine.
3. Measure the angle of your driveshaft.
4. Measure the pinion angle at the rear axle.

Ideal Angles: For a smooth ride, the transmission output angle and the pinion angle should be equal but opposite. For example, if your transmission points down 3 degrees, your pinion should point up 3 degrees. The total operating angle should not exceed 4-5 degrees.

Once you know the needed correction, you can select the right shim from your shim suspension kits. A 2-degree shim, for instance, will change the pinion angle by 2 degrees. This small adjustment can completely eliminate driveline vibrations. The relationship between your driveshaft’s operating angle and its maximum speed is important. A steeper angle limits how fast the driveshaft can safely spin.

Using custom precision shims to set the correct pinion angle is vital for the health of your driveline. It prevents premature wear on U-joints and ensures a smooth transfer of power. The right precision shim from your shim suspension kits protects your suspension and drivetrain. Max provides high-quality custom precision shims and suspension shims to help you get the job done right. Each shim is a key part of a well-tuned suspension.
