Complete Driveline Systems for 4-Cycle Karting

In low-horsepower racing like LO206 and Clone, driveline efficiency is free horsepower. A binding chain, a worn sprocket, or a dragging clutch can cost you tenths of a second per lap. We stock high-performance clutches, chains, gears, and hubs designed to transfer every bit of power from your crankshaft to the rear tires.

The Big Debate: #35 vs. #219 Pitch

Most LO206 and 4-cycle racers must choose a chain size. Your clutch driver must match your rear sprocket.

• #35 Chain: The standard for US club racing. It is robust, affordable, and resists derailing on bumpy tracks. (Tooth counts are smaller, e.g., 15T Driver / 58T Rear).
• #219 Chain: Common in 2-cycle and some LO206 classes. It is lighter, runs smoother, and offers finer gear ratio adjustments. (Tooth counts are higher, e.g., 19T Driver / 74T Rear).

Gear Ratio Tuning

Changing your rear sprocket size is the easiest way to tune for a specific track.
Larger Rear Sprocket: Better acceleration (Corner exit), lower top speed.
Smaller Rear Sprocket: Higher top speed (Long straights), slower acceleration.
We recommend carrying a range of split sprockets (e.g., 58-64 for #35 chain) to adapt to track conditions.
