Eliminate drive-line flex and maximize power transfer to the track with the Performance Manufacturing 1 1/4" Heavy Duty Sprocket Hub, a mandatory upgrade when sourcing premium kart parts online. Engineered from billet aluminum and finished in a rugged black anodize, the APH125B-HD sprocket hub is built to clamp down on your 1 1/4-inch axle with zero slip. Whether you are running a high-horsepower two-stroke or tuning your setup with a fresh lo206 carburetor kit, maintaining perfect chain alignment is critical. This heavy-duty hub utilizes a thick, robust profile that resists deformation, ensuring your sprocket stays true even after aggressive curb strikes or violent standing starts.

Essential Drive-Line Upgrades and Carburetor Parts

While many drivers focus on engine tuning and carburetor parts to find extra tenths, a flexing sprocket hub will rob you of that hard-earned horsepower before it ever reaches the tires. The Performance Manufacturing heavy-duty hub features a standard 6-bolt pattern, making it universally compatible with most performance sprockets and guards. Its extra-wide clamping area provides superior bite on the axle, eliminating the spin-outs and keyway shearing that plague lighter, inferior hubs in senior classes.
