Description
xRUTU ATV Rear Sprocket 37T — robust gearing for your quad
Designed for a wide range of small-displacement ATVs and quads, this rear sprocket is built to withstand the rigors of trail riding and daily tasks. It is compatible with 420-type chains, commonly found on 50cc, 110cc, and 125cc models from brands like Tao, Roketa, Coolster, Kazuma, Sunl, and others. Before you order, verify your chain size and the mounting hole spacing (68mm center-to-center or 48mm for adjacent holes) to ensure a perfect fit.
Durable, precision-made construction
Crafted from premium steel, the sprocket offers corrosion resistance and long-lasting performance in mud, rain, and dirt. A heat-treated finish hardens the metal, improving strength and wear resistance, while a thoughtfully engineered radius curve between teeth helps reduce transmission friction and smooth power transfer.
- 68mm mounting hole spacing (center-to-center) for opposite holes; 48mm spacing for adjacent holes.
- Built to endure the vibrations and impact of off-road riding with dependable steel composition.
Gearing for real-world use
The rear sprocket size you choose changes how your ATV behaves on hills and trails. Without changing the front sprocket, reducing the number of teeth can increase top speed, while increasing the teeth count boosts torque for steeper climbs. Consider pairing with the front sprocket to balance acceleration and performance for your terrain.
- Increased teeth imply more torque for hill climbing and heavy acceleration scenarios.
- Fewer teeth can offer higher gearing for faster sectioned runs on flat terrain.
Each kit includes mounting screws for a straightforward installation, so you can complete the upgrade with common tools and confident alignment.
