Designed specifically to mate with SMC AP8 small or AP9 medium aluminum sprocket guards, this lightweight nylon spacer transforms your standard guards into a highly efficient sprocket guide system. By providing the exact clearance needed to prevent chain rub, it ensures your #35 or #219 chain tracks perfectly straight, maximizing power transfer from the clutch to the rear axle. Whether you are running a high-revving 2-cycle or maximizing your \u003cstrong\u003ebriggs and stratton lo206 horsepower\u003c\/strong\u003e, maintaining a free-spinning driveline is critical for preserving momentum out of tight corners.\u003c\/p\u003e\n\u003ch2\u003eBeyond Go Kart Wheels: Optimizing Driveline Efficiency\u003c\/h2\u003e\n\u003cp\u003eWhile many racers focus entirely on tire pressures and \u003cstrong\u003ego kart wheels\u003c\/strong\u003e for grip, neglecting your chain path will scrub off valuable speed. The SMC plastic guard spacer acts as a buffer, absorbing vibration and resisting the intense heat generated during long feature races. When you sandwich this spacer between two AP8 or AP9 guards, you create a rigid, friction-free channel that prevents the chain from derailing over aggressive curbs. This precise alignment reduces the risk of binding, ensuring that every ounce of torque reaches the track surface.\u003c\/p\u003e\n\u003ch2\u003eComplement Your Brakes and Parts with Driveline Security\u003c\/h2\u003e\n\u003cp\u003eA dropped chain can end your weekend just as quickly as a blown motor.
