Frequently Asked Questions (FAQs)

Should I replace both trailing arms if only one is bent?

While not strictly necessary, many riders choose to replace them in pairs to ensure even bushing wear and perfectly symmetrical suspension response. At a minimum, always inspect the bushings and mounting points on the opposite side when replacing one Polaris UTV OEM Trailing Arm.

Can a bent trailing arm cause axle failure?

Yes. If the arm is even slightly out of alignment, it puts the CV axles at an unintended angle. This leads to overheating, torn boots, and eventual joint failure. Replacing a damaged arm immediately is the best way to avoid a more expensive drivetrain repair.
