Reinforced Pulleys for Consistent Running

The Serpent 804113 Middle Pulleys Set brings reinforced nylon strength to your vehicle's centre pulleys, helping keep rotations true under load. The set includes both 18T and 21T sizes so you can adjust tuning to suit conditions.

True Running with Debris Relief

These pulleys are finished to reduce wobble and limit friction, improving torque transfer. Built-in side ports let dust and grit escape, lowering the chance of abrasive wear in rough or off-road environments.

Flexible Upgrade for Many Chassis

Whether you are swapping worn parts or dialing in gear ratios, the 18T and 21T items are useful spares. Their robust construction makes them suitable for frequent use in competitive or casual settings.

Are these pulleys suitable for off-road use?

Reinforced nylon gives good wear resistance for light off-road use, but heavy mud and water exposure will still require regular cleaning and inspection.

Do the pulleys need special lubrication?

They do not need heavy lubrication; a light application of suitable plastic-safe lubricant at service intervals helps maintain smooth running.

How do I choose between 18T and 21T?

Use the 18T for quicker acceleration and the 21T for slightly higher top speed; trial both to find the best balance for your track.

Any tips for installation?

Check pulley alignment, ensure set screws are secure, and spin the assembly by hand before putting the model back on the track.
