Stabilizer Bar Mount Bracket (42415-66D00) by Suzuki

Clunks over bumps, a wandering front end or a quad that sits low on one corner usually mean worn suspension parts. The Suzuki KingQuad Stabilizer Bar Mount Bracket (part number 42415-66D00) is the genuine Suzuki replacement. It is a factory Suzuki suspension part made to fit the stock geometry of your ATV.

Why Choose Suzuki

Suzuki says its Genuine Parts are the same parts used to build every Suzuki product, and each one is designed for a specific product and model. 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.

Why Stock Geometry Matters

Suzuki sets up its A-arms, shocks, swingarms and sway bars to work together. Bushings and pivots wear over time, and the play adds up. Replacing worn parts with the factory parts brings the handling back to how it left the factory.

Bent parts are a different problem. If an arm or swingarm is bent from a hit, replace it rather than straightening it.

How to Check for Wear

With the wheels off the ground, rock each wheel top to bottom and side to side. Look for play at bushings and ball joints, leaking shocks and cracked or bent arms.

Genuine parts also make the next repair easier. When every part on the machine matches the Suzuki parts diagram, you can look up the right replacement by part number, follow the service manual without surprises and know the part will line up with its mounts, fittings and neighbors. That saves time in the shop and on the trail.

Buying Guide

• Part number: Match 42415-66D00 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 2007–2018 models.
• Replace in pairs: Do left and right together to keep the ride even.
• Check the hardware: Pivot bolts and collars wear along with bushings.

Installation

Suspension work requires supporting the ATV securely with the wheels off the ground. Torque pivot bolts with the suspension at ride height where the manual calls for it. Follow the Suzuki service manual or the manufacturer's instructions for your model.

Before You Install

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

Care and Maintenance

Grease fittings where your model has them, wash mud out of pivots and check for play during regular service.
