RADHLBNIU ATV Carrier Bearing for Polaris RZR S 1000 (2016–2020) — Billet Aluminum, Heavy-Duty

If your Polaris is showing driveline vibration, premature bearing wear, or noisy operation around the center carrier area, replacing the worn carrier bearing with a durable billet-aluminum unit can return smoothness and extend component life. This RADHLBNIU assembly fits many popular full-size and midsize Polaris models — including multiple RZR S, XP and Ranger XP 1000 years — and replaces part numbers 3514900, 3515075 and 3514806.

Which Polaris models will this carrier bearing fit?

This bearing is manufactured to match the dimensions and mounting points used on a wide range of Polaris machines. It is compatible with late-model Ranger XP 1000 and numerous RZR variants, but not all trims and turbo versions. Always verify model year and trim before ordering to ensure proper fit.

• Compatible examples: Ranger XP 1000 (2018+), RZR S 1000 (2016–2020), RZR S4 1000 (2019–2020), RZR XP 1000 (2014+).
• Also fits multiple RZR 900 and Trail 900 configurations (see full fitment list).
• Not compatible with RZR XP 4 Turbo models — confirm against your VIN or service manual.

How does the billet-aluminum construction benefit drivetrain performance?

Billet aluminum provides a stiffer, more stable housing than low-grade cast or pressed alternatives. That stability reduces side loads transmitted to the internal bearing, which minimizes vibration and helps bearings last longer under heavy off-road use.

• Precision machined billet housing for consistent alignment under load.
• Reduced side-load transfer lowers wear on both carrier and drive shaft bearings.
• Aluminum dissipates heat faster than some alloys, aiding long-term durability.

What comes with the bearing and how difficult is installation?

The part arrives as a ready-to-install carrier bearing assembly sized to replace OEM part numbers listed. Though installation is straightforward for experienced mechanics, correct alignment and torque are important for long service life, so professional installation or a competent DIY mechanic with proper tools is recommended.

• Supplied as a complete carrier-bearing assembly — no additional housings required.
• Direct-replacement for listed part numbers: 3514900, 3515075, 3514806.
• Installation note: professional installation advised to ensure correct drive-shaft alignment.

Will this bearing reduce noise and vibration I’m feeling while driving?

Replacing a worn carrier bearing with a new, precision-machined unit often reduces mid-chassis vibration and noise. While this part addresses carrier-bearing-related symptoms, other drivetrain components should be inspected to eliminate all possible causes of vibration.

• New bearing restores proper support to the drive shaft, diminishing wobble and chatter.
• Helps prevent premature wear on adjacent bearings and universal joints.
• Best results when combined with a complete drivetrain inspection and correct installation.

Who is this for: This RADHLBNIU billet-aluminum carrier bearing is intended for Polaris owners, professional mechanics, and off-road enthusiasts who need a heavy-duty, OEM-replacement-quality carrier bearing for RZR and Ranger models listed in the fitment. Choose this part if you want a durable, precision-machined replacement to address center-drive vibration and extend the life of your drivetrain, and be sure to confirm your vehicle model and part number before purchasing.
