Shim tuning tips: how changing just one shim transforms suspension

Did you know that swapping out a single shim can completely change how your suspension performs? Shim tuning is one of the most powerful - yet often overlooked - tools in damper adjustment. In this video, we test different shim changes on a compression double-stage shim stack, compare them to stock settings, and explain the results. You’ll see how subtle tweaks affect damping across low, mid, and high speeds, and when to use stiffer or softer setups for better control. Whether you’re tuning for motocross, mountain bikes, or motorsport, mastering shim changes can unlock new levels of suspension performance.

In today’s testing series, we’ll make a single shim adjustment to the compression double-stage shim stack, compare it with the stock setting, and dive into the results. What works, what doesn’t, and why? Let’s get right to it and start shimming. First up, we added a 44-millimeter diameter and 0.20-millimeter thick shim to the low-speed circuit. By stiffening it, we observed a subtle but consistent increase in damping across all cycles. Expect about a 4% bump across low, mid, and high speeds. This tweak is ideal if you’re after more bike or vehicle stability — especially when your clickers have maxed out or can’t offer more compression damping. Next, we swapped the 36-millimeter diameter and 0.15-millimeter-thick crossover shim for a 30-millimeter diameter and 0.20-millimeter-thick shim, making things softer. At first glance, the change might look subtle, but the difference shows clearly in performance once tested. Now let’s tackle the high-speed circuit. We added a 42 millimeter diameter and 0.30 millimeter thick shim to stiffen things up. The results are unmistakable: a strong increase in damping force at higher shaft speeds. This change improves control and stability in aggressive riding conditions, making the shock more composed under heavy impacts or rough terrain. We also tested the opposite adjustment — replacing a 40 millimeter diameter and 0.25 millimeter thick shim with a 38 millimeter diameter and 0.15 millimeter thick shim. This softer setup reduced the damping force at high shaft speeds. The benefit here is improved comfort and better traction on small bumps, though it comes at the cost of less support under harsh impacts. As you can see, even the smallest shim adjustments can make a significant difference in suspension performance. Low-speed changes influence overall stability and chassis balance. Crossover changes control initial stroke comfort while keeping peak damping steady. High-speed changes determine how the suspension reacts to aggressive hits and rough terrain. Mastering shim tuning is about knowing when to stiffen for stability or soften for comfort and traction. With precise testing, you can unlock suspension performance tailored to any rider or condition. Even small shim adjustments can make a big impact — and knowing how to apply them is key to precision suspension tuning. #ShimTuning #SuspensionTuning #ShockDyno #LABA7 #MotorsportEngineering Follow us!   / labaseven     / laba_seven     / laba7     / laba_seven
