Nut (64872-08H00) by Suzuki

A clunk when you take off, a vibration through the floorboards or gear oil on the inside of the wheel means something in the driveline is worn. The Suzuki QuadSport Z90 Nut (part number 64872-08H00) is the genuine Suzuki replacement. It is a factory Suzuki drivetrain part from the gearcases, driveshafts or axles that carry power to the wheels.

Witchdoctors carries Suzuki drivetrain parts for ATVs. Check the fitment, options and tips below, and contact our team with any questions before you order.

Why Choose Suzuki

According to Suzuki, these parts are tested for performance, quality, durability, safety and comfort. Suzuki also introduced the world’s first four-wheel ATV, and it still builds the KingQuad and QuadSport lines today.

Fitment and Compatibility

Listed for 15 model configurations from 2007–2026, including 2026 QuadSport Z90. Use the fitment tool on this page to confirm your year and model.

The fitment list skips some years in that range (2010, 2011, 2012, 2013, 2024), so check your exact year. Suzuki sometimes supersedes part numbers. If the number on your old part is different, or your model isn't listed, contact our team before you order.

How Power Gets to the Wheels

On 4x4 Suzuki ATVs, power leaves the transmission through propeller shafts to the front and rear gearcases, then out through axles to the wheels. Bearings, seals, gears, U-joints, boots and hardware keep that path tight and clean.

A torn boot or leaking seal lets water and dirt in, and that's where most driveline damage starts.

Signs of Wear

Clicking when turning, a clunk on takeoff, vibration, gear oil leaks and play in a shaft or axle are all signs. Check boots and seals during every service.

Buying Guide

• Part number: Match 64872-08H00 to the number on your old part or your Suzuki parts diagram.
• Fitment: Confirm your year and model in the fitment tool; this part is listed for 2007–2026 models.
• Catch boots early: Replacing a torn boot is much cheaper than replacing a joint.
• Fresh gear oil: Refill gearcases with the oil Suzuki specifies after any repair.

Installation

Most driveline work starts with removing the wheel and supporting the machine securely. Gearcase internals usually need special tools and careful shimming per the Suzuki service manual. Follow the Suzuki service manual or the manufacturer's instructions for your model.

Before You Install

Support the ATV on stands, not just a jack. Have the Suzuki service manual and a torque wrench ready.

Care and Maintenance

Inspect boots, seals and gearcase oil during regular service, and after deep water rides.
