The 16mm Shock Shim Semi-Solid 1/8in 25pk from ALLSTAR PERFORMANCE is a chassis-tuning spacer made for shocks built on a 16mm shaft. Each shim measures 1/8 inch thick and 16 mm in diameter, molded from green plastic, and the pack ships 25 pieces. Racers and chassis builders use these to fine-tune ride height and limit shaft travel on the fly, without pulling a shock apart. If you run a stack of shocks across a setup, having a box of these on the bench saves time between sessions.
Because the shim is semi-solid plastic rather than a split or threaded collar, it slides directly onto the 16 mm shaft and sits against the shock body or another shim. That lets you add or pull shimmed travel quickly between rounds. The 1/8 inch thickness gives you a usable increment for dialing limited shaft travel, and the 25-piece count means you can build up a stack in either direction without running short mid-weekend. The 16 mm bore is sized specifically for 16mm shock shafts, so it indexes cleanly without slop. Builders who also work with threaded adjusters often pair these with shaft spacers for coarser changes and reserve the shims for finer corrections.
Reach for these when you need to cap shaft travel or shift ride height a measured amount between heats and don't want to tear a shock down to do it. The green color makes them easy to spot in a crowded shock cart, and the 25-pack covers a multi-car program or a full season on one chassis. Keep a few thicknesses on hand so you can mix increments as conditions change. Browse the rest of our suspension and components for shafts, spacers, and rebuild parts that work alongside these shims.
These shims are bored for 16 mm shock shafts. The 16 mm diameter indexes onto the shaft cleanly so the shim sits square against the shock body or an adjacent shim. They are not intended for other shaft diameters, so match them to shocks running a 16mm shaft.
Each shim measures 1/8 inch thick. That increment lets you build a stack to limit shaft travel or shift ride height a measured amount. With 25 pieces in the pack, you can add or remove shims in 1/8 inch steps without running short.
No. Being semi-solid plastic, each shim slides directly onto the shock shaft. You can add or pull shims for chassis fine-tuning without tearing the shock down, which makes them quick to adjust between heats or sessions.
This is a 25-pack of 1/8 inch shims. That count covers a multi-car program or a full season on a single chassis, with enough on hand to build a stack in either direction during a race weekend.
