Starter Box Shim Set for ProtekRC Starter Boxes

Getting reliable flywheel contact on a ProTek RC starter box can be frustrating with the stock motor mount height. A common fix is stacking washers under the motor mount, but balancing multiple washers across four screws is tedious, awkward, and makes future adjustments a hassle.

This Starter Box Shim Set for ProTek RC Starter Boxes makes the process quick, clean, and repeatable. Instead of fighting with loose stacks of washers, this kit uses full-size shim plates that align with all four motor mount holes at once. Think of them as one large precision washer plate that keeps everything aligned during installation while making height changes dramatically easier.

The set includes 2mm, 4mm, and 6mm shim plates, allowing you to run them individually or stack them in any combination to dial in the exact starter wheel height needed for solid flywheel engagement.

To complete the upgrade, the kit also includes stainless steel flanged button head screws in two lengths, so you have the correct hardware whether running a single shim or a stacked setup. The flanged heads eliminate the need for separate washers while spreading load better across the starter box chassis, and the stainless construction helps resist rust far better than stock screws.

This is a simple but highly effective upgrade that makes starter box setup easier, cleaner, and far less frustrating.
