Eliminating drivetrain friction is the fastest way to lower your lap times, and as a leading go kart shop, we recommend the SMC SM-PS Plastic Sprocket Guard Spacer to achieve exactly that. 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 briggs and stratton lo206 horsepower, maintaining a free-spinning driveline is critical for preserving momentum out of tight corners.
Beyond Go Kart Wheels: Optimizing Driveline Efficiency
While many racers focus entirely on tire pressures and go kart wheels 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.
Complement Your Brakes and Parts with Driveline Security
A dropped chain can end your weekend just as quickly as a blown motor. While investing in top-tier engine rebuilding kits is essential for power, the SMC spacer is your insurance policy for reliability. It standardizes your rear-end setup, allowing for rapid gear changes in the pits without having to re-measure clearances. Just like upgrading your brakes and parts for deeper corner entry, installing this spacer gives you the confidence to push the kart to its absolute limits without fear of mechanical failure.
