Gekufa 48-Tooth Go Kart Sprocket for #40 #41 420 Chain — Heavy-Duty Steel, 2" Bore

Gekufa 48-tooth steel sprocket engineered for #40, #41 and 420 chains—built to replace or upgrade rear-axle drive on go karts, mini bikes, ATVs and small utility machines.

If you need a durable replacement sprocket that fits common small-vehicle chain systems, this 48-tooth Gekufa sprocket is designed to deliver consistent chain engagement and long service life. Machined from heavy-duty steel and sized to standard mounting dimensions, it helps restore drivetrain performance where a worn or mismatched sprocket has caused slipping, noise or accelerated chain wear.

How do I confirm this sprocket will fit my vehicle?

Measure your existing sprocket and hub before ordering. Key dimensions to verify are the center bore, overall outside diameter, mounting hole spacing and compatible chain size. If any measurement differs, the sprocket may not mount correctly or could cause premature wear.

• Center bore: 2 inches (measure across hub bore).
• Outside diameter: 7-7/8 inches (full sprocket diameter).
• Mounting holes: 3/8" diameter; spacing 2" side-by-side and 2-9/16" across.
• Chain compatibility: #40, #41, or 420 chains only (not #35).

What materials and build quality can I expect from the Gekufa 48T?

The sprocket is fabricated from heavy steel for strength under load and consistent tooth profile for stable chain engagement. That solid construction helps resist bending and maintains alignment on rough terrain or under high torque conditions.

• Material: heavy-duty steel for toughness and durability.
• Tooth count: 48 teeth cut to fit specified chains.
• Finish: machined edges for smoother chain transition.
• Designed for rear axle chain drive systems in outdoor use.

Which vehicles and setups is this sprocket suitable for?

This part is intended for go karts, mini bikes, ATVs, drift trikes and small farm or utility equipment that use #40, #41 or 420 chains. It is not a universal fit—verify hub mounting pattern and bore before installing.

• Typical applications: recreational go karts, mini dirt bikes and small ATVs.
• Also fits: drift trikes, small utility trailers, and some farm implements when dimensions match.
• Not included: hub adapter, bolts, nuts or chain—sprocket only.
• Not compatible with: #35 chain systems.

How should I prepare for installation and maintenance?

Gather the correct hardware and confirm bolt pattern alignment before fitting the sprocket. Regular inspection of chain tension and tooth wear will extend drivetrain life and keep the system running quietly and efficiently.

• Required items not included: replacement bolts, nuts, or a hub adapter if needed.
• Installation tip: clean mating surfaces and check bore for burrs before mounting.
• Maintenance: re-torque fasteners after initial run-in and inspect chain wear periodically.
• Safety: ensure proper chain guard and alignment to avoid derailment.

Who is this for: The Gekufa 48-tooth sprocket is aimed at DIY mechanics, kart racers, hobbyists and small equipment owners who want a robust replacement component for #40/#41/420 chain drives. Choose this sprocket if your current unit meets the listed measurements and you need a heavy-steel option that restores reliable power transfer on recreational or light-duty work machines.
