Precision-machined for maximum power transfer, the Noram Star NASD13 Billet 13-Tooth #35 Clutch Drum is one of the most critical go kart components for racers demanding immediate throttle response. By drastically reducing rotational mass, this CNC-machined billet aluminum drum allows your powerplant to spool up with zero hesitation. In competitive racing, where inertia is the enemy of acceleration, shedding weight at the clutch assembly translates directly to faster corner exits and superior straight-line speed.
Optimized for the Modern Two Cycle Engine
High-revving powerplants require drivetrains that can handle extreme thermal loads and rapid RPM spikes. This drum is engineered to withstand the brutal harmonics of a high-output two cycle engine, ensuring your clutch shoes engage with absolute consistency. The superior ventilation channels actively dissipate heat during grueling endurance runs, preventing the clutch fade that plagues stamped steel alternatives. Whether you are tuning for a high-speed asphalt sprint or a tight dirt oval, the NASD13 delivers a harmonious balance of torque multiplication and top-end speed.
Essential Parts Mini Sprints and Karts Rely On
When building a championship-winning chassis, every ounce matters. As one of the premier parts mini sprint and kart builders trust, this billet drum offers unparalleled structural rigidity. The precision-cut splines guarantee a wobble-free sprocket mounting surface, eliminating parasitic drag and chain derailments. Maintenance is streamlined, allowing pit crews to perform rapid post-race inspections and spring swaps.

Frequently Asked Questions
Q: Why should I choose a billet aluminum drum over a stamped steel version?
A: Billet aluminum offers superior structural rigidity and heat dissipation. Unlike stamped steel, which can warp or "bell-mouth" under the extreme heat and high RPMs of competitive racing, the NASD13 maintains its shape to ensure consistent clutch shoe engagement and prevent power-robbing drag.
Q: Is the NASD13 compatible with all #35 chain setups?
A: Yes, this drum is specifically engineered for #35 chain compatibility. The precision-cut splines ensure a perfect, wobble-free fit for your sprocket, which is essential for maintaining proper chain alignment and preventing derailments during high-speed cornering.
Q: How does the 13-tooth configuration affect my kart's performance?
A: The 13-tooth configuration is designed to provide an aggressive torque curve. It is ideal for tight, technical track layouts where rapid acceleration out of corners is more critical than top-end speed.
Q: What maintenance is required for the Noram Star billet drum?
A: To ensure longevity, perform regular post-race inspections to check for debris or excessive clutch dust buildup within the ventilation channels. Because the drum is precision-machined, keeping the spline area clean and lightly lubricated will ensure smooth sprocket swaps and consistent performance.
Q: Can I use this drum with my existing Noram Star clutch shoes?
A: Yes, the NASD13 is part of the Noram Star ecosystem and is perfectly calibrated to house Noram Star clutch shoes and engagement springs, ensuring a seamless fit and optimal friction engagement.
