Getting your suppressor to sit square on the muzzle isn't just about aesthetics — it's about reliability, accuracy, and longevity of both the can and your rifle. The Dead Air DA002 5/8-24 Shim Kit gives you precision suppressor alignment with a set of precision-engineered shims designed specifically for 5/8-24 threaded barrels. Whether you're running a precision rifle, a hunting gun, or an SBR, these shims let you dial in perfect concentricity without guesswork or permanent modifications.
Dead Air includes three different shim thicknesses in the DA002 kit, each marked for quick identification. The variety of thicknesses and rotation increments means you can fine-tune alignment in small, predictable steps until your suppressor sits dead-center on the bore. Start with the thickest shim on the barrel first, then work your way to thinner options as needed — it's a methodical approach that beats trial-and-error stacking or creative problem-solving with washers.
These shims are purpose-built for shooters who understand that suppressor alignment directly affects accuracy, reduces first-round pop, and keeps your can running smoothly through extended shooting. If you're precision-minded about your rig, whether you're tuning a long-range hunter or a precision target rifle, this kit gives you the control to get it right.

Frequently Asked Questions
Will this Dead Air shim kit work with my 5/8-24 threaded barrel?
Yes — the DA002 is specifically designed for 5/8-24 threads. Dead Air also makes a separate shim kit for 1/2-28 if that's your thread pitch.
How do I use these shims to align my suppressor?
Install the thickest shim (.060″) on the barrel first, thread on your suppressor, and check concentricity. If you need to adjust, remove the suppressor and swap to a thinner shim or combination of thinner shims until alignment is dialed in. Each shim size has a specific rotation increment, so you'll know exactly how much you're moving with each change.
What's included in the kit?
The kit includes four .004″ shims (one notch), five .006″ shims (two notches), and one .060″ shim (no notch) — a total of ten shims in three thickness grades to give you fine and coarse adjustment options.
Can I use these shims on a different suppressor brand?
These shims are designed for any suppressor with a 5/8-24 female thread, not just Dead Air suppressors. As long as your suppressor has 5/8-24 threads and your barrel is 5/8-24 male, the shims will work.
