A-Arm Bearing Kit with Shaft for Polaris Trail Boss 350

This A-Arm Bearing Kit with Shaft is a suspension rebuild set for Polaris Trail Boss 350 2x4 and 4x4 machines, supplying the bearings, seals, and pivot shaft needed to bring a worn front A-arm back to smooth, tight operation.

Overview

This A-Arm Bearing Kit with Shaft lets you service the front suspension pivot on a Polaris Trail Boss 350 without replacing the entire arm assembly. The kit refreshes the bearing set and pivot shaft so the A-arm swings freely and steering stays predictable under load. It is aimed at Trail Boss 350 owners and small-shop mechanics handling their own front-end repairs on 1993 2x4 and 4x4 models.

Specs At A Glance

Good To Know

Q: What symptoms point to a bad A-arm bearing? A: Clunking over rough ground, free play at the front wheel, or an arm that binds when moved by hand all indicate worn pivot bearings. This kit replaces those wear parts along with the shaft.

Q: Is this kit the same for 2x4 and 4x4 Trail Boss 350 models? A: The 1993 Trail Boss 350 2x4 and 4x4 share the same front A-arm design, so this kit services both. Always confirm your model year and serial number before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
