Heavy Duty Double Groove V Belt Pulley For 20mm Shafts
✔️ 20mm Bore 54mm OD 52mm Height 35mm Hub Diameter Fits

This solid metal drive wheel channels rotation from 168F and 170F motors straight to your chassis. Builders slap these on go kart frames and mini tractors to fix worn out sheaves. The setup runs smooth under heavy loads without frying your drive belts. Check your crankshaft size before bolting it down since the hole only accepts twenty millimeter spindles.

✅ 20mm bore width locks tight onto standard aftermarket crankshafts ✅ Twin 12mm V notches lock drive belts in place against vibration ✅ 54mm face width clears wider chain sprocket covers on most builds ✅ Heat treated alloy steel stands up to constant torque spikes ✅ Requires user drilling for set screws since factory hardware omits them

💡 How does a double groove drive pulley improve power transfer over single track bushings?
Swapping units like this is pretty handy because you skip machining custom flanges. The wider footprint grabs the belt tighter so you stop losing ground speed when hitting hard acceleration marks.
- Extended ribbing creates more friction surface area to kill belt hop under max throttle conditions
- Hardened steel construction handles constant torque spikes without warping near exhaust manifolds
- Matched pitch profiles grip standard A and B series timing belts found in most backyard shops
- Standard mounting diameter slides right onto 20mm mandrels without needing extra adapters or weld patches
