FQRANBO Rear A-Arm Bushing Shaft Kit for Polaris Sportsman 400-800 — Pair, ABS/Aluminum/Iron Durable Replacement

FQRANBO Rear Left & Right A-Arm Bushing Shafts Kit replaces worn pivot hardware on Polaris Sportsman 400–800 models to restore factory fit and stable suspension movement.

This replacement kit contains the shafts, bolts, and components needed to rebuild the rear A-arm assemblies on compatible Polaris Sportsman ATVs. Built from ABS, aluminum and iron, the parts are engineered to resist impact, rust and deformation so they can survive regular outdoor use. The kit is sold as a pair for both left and right rear A-arms and matches multiple OEM part numbers for straightforward fitment.

Which Polaris models and OEM numbers does this kit fit?

The kit fits a broad range of Polaris Sportsman 400, 450, 500, 600, 700 and 800 model years—check your year and trim against the listed part numbers before ordering. It is designed to replace several OEM references so you can match the worn part directly without modifying the A-arm.

• Compatible models: Sportsman 400 / 450 / 500 / 600 / 700 / 800 (verify with your VIN/service manual)
• Replaces OEM part numbers: 5020826, 5434548, 5434551, 5133806, 5434550 and others
• Includes both rear left and rear right shafts for full axle-side rebuilds

How does this kit restore suspension performance?

Worn A-arm bushings or shafts create excess play at the pivot, which shows up as sloppy steering, uneven tire wear and reduced traction. Replacing the shafts to factory-like dimensions removes that unwanted movement and helps the A-arm track as designed.

• Restores correct pivot geometry and reduces lateral play
• Helps tires maintain better ground contact for improved traction
• Durable materials resist bending, corrosion and impact in off-road conditions

What materials and quality features are included?

The kit combines ABS, aluminum and iron components chosen for strength and environmental resistance. The mix of materials balances weight, rigidity and long-term corrosion protection so the shafts maintain dimensional stability under load.

• ABS components for impact resistance and reduced corrosion risk
• Aluminum for lightweight strength where needed
• Iron hardware for durable load-bearing surfaces and secure fastening

How easy is installation and what should I prepare?

Installation is a direct swap for the rear left and right A-arm pivot shafts if your ATV matches the listed OEM numbers. Basic mechanical skill, hand tools, and torque specs from the Polaris service manual are typically all that’s required for a professional, secure install.

• Direct-fit replacement—no custom machining required
• Requires basic tools, torque wrench, and a safe lift or jack stands
• Inspect A-arm bearings and seals during service and replace if worn

Who is this for: This FQRANBO rear A-arm bushing shafts kit is intended for Sportsman owners, ATV mechanics and restoration projects needing a reliable rear pivot rebuild. If you own a Polaris Sportsman 400–800 and notice play in the rear suspension, uneven tire wear, or want to refresh worn pivot hardware to factory-like specifications, this kit provides the parts to perform a lasting repair.
