KAX 4x156 ATV Wheel Spacers 2in - Robust Forged Aluminum Upgrade

In this review the KAX 4x156 ATV wheel spacers are evaluated for riders who need a reliable way to widen track and correct aftermarket wheel offset. The single biggest reason to buy is their forged 6061-T6 construction paired with SGS certified 10.9 grade hardware, which delivers a solid, durable adapter for 4x156 bolt pattern ATVs. Installation is straightforward for anyone comfortable with basic wheel work, and the spacers address clearance and stance issues without expensive suspension changes.

Key Features

• Forged 6061-T6 aluminum: Provides aircraft-quality strength and consistent dimensional accuracy for long-lasting use.
• 2 in (50.8mm) thickness: Widens the vehicle track enough to improve stability and correct offset issues from aftermarket wheels.
• M12x1.5 threaded studs and nuts: Comes with durable studs and SGS certified 10.9 class split nuts for secure wheel mounting.
• 131mm center bore with no lip: Fits hub-centric installations where a lip is not required and allows compatibility with the listed hub sizes.
• Complete bolt-on kit: Ships with four spacers, nuts and a professional instruction manual to simplify installation.
• Recommended torque spec: Clear guidance of 70-80 ft/lbs helps ensure correct fastening and safe use.

Who It's For

The spacers are best for owners of 4x156 bolt pattern ATVs who need to correct wheel offset, increase track width for better stability, or clear fenders when using wider tires or aftermarket wheels. They suit experienced DIYers and mechanics who can confirm wheel stud length and available fender clearance before installation.

Riders who should look elsewhere include those with non 4x156 bolt patterns or vehicles lacking at least 2 in of clearance between fender and tire, and anyone uncomfortable trimming wheel studs if required - professional shop fitting is recommended in those cases.
