Chain Pulley Roller Slider M8

This M8 chain pulley roller slider fits most dirt pit bikes, street bikes, motorcycles, ATVs and off-road vehicles. The package includes one roller, one nut, one bolt and two gaskets for a complete installation kit. Riders who need a replacement guide for worn original equipment will find the 26 mm total length and 8 mm inner diameter match many common setups. Buyers with non-standard axle spacing or proprietary tensioner designs should verify fitment before ordering.

Durable Rubber Metal Construction

The roller combines rubber and metal materials that are waterproof and hard-resistant for extended service life. Duty bearings come pre-installed so the unit rolls smoothly under continuous chain tension and vibration. Professional installation is recommended to ensure correct torque on the M8 x 1.25 spread size and proper alignment. The component is not suited for applications that exceed the specified dimensions or require sealed ceramic bearings.

Upgrade From Worn OE Rollers

This slider replaces factory chain guides that have developed flat spots, bearing play or cracked rubber after prolonged off-road use. The 35 mm outside diameter restores proper chain tracking and reduces drivetrain noise on compatible models such as the Yamaha YFZ350. The improvement is worthwhile when the original roller shows visible wear or the chain begins to skip under load. Riders running oversized chains or custom swingarm pivots should confirm clearance before swapping.

Questions about this item

Does the 8 mm inner-diameter pulley run quietly and stay cool during all-day riding?

The rubber-and-metal roller uses sealed duty bearings designed for continuous chain contact, so friction stays low and heat build-up is minimal on long rides.

What tools or existing parts are needed to bolt on the M8 × 1.25 spread-size slider?

The kit includes the roller, one nut, one bolt and two gaskets; you only need standard M8 wrenches or sockets to secure it to the swing-arm mount.

Will the 35 mm outside-diameter guide clear the stock chain on a Yamaha YFZ350 without modification?

Yes — the 35 mm OD matches the OEM spec for the YFZ350, so the chain tracks correctly with no spacer or filing required.
