All Balls Racing A-Arm Rebuild Kit 50-1165

For a targeted suspension repair, a rebuild kit can make more sense than replacing a complete A-arm. This All Balls Racing kit is intended to rebuild one A-arm, not a full set.

It includes the bearings, bushings, bearing shafts, seals, shims, and spacers needed for that job. The fitment list is vehicle-specific, so the exact model and year matter.

A solid pick if your Polaris is among the listed applications and you need the components for one A-arm rebuild. It might not be a great match if you need parts for multiple arms or your machine’s exact configuration is not listed.

Technical details

The kit is described as a direct OEM replacement and is supplied to rebuild one A-arm. Its contents cover the wear and support components named in the product information: bearings and bushings, bearing shafts, seals, shims, and spacers. That makes it a parts-focused repair option rather than a complete A-arm assembly. The stated fit type is vehicle-specific, no dimensions or material details are provided.

Requirements

Listed ACE applications include the 325 for 2016, 500 for 2017–2018, 570 for 2016–2017, and 900 EFI EPS for 2016. The listed Sportsman fitments include 450 HO for 2016–2018 and 450 HO 2x4 MD for 2016, 570 6x6, 570 EFI, 570 EFI X2 EPS, and Touring 570 EFI for the years specified in the fitment list, plus 570 SP and Touring 570 SP applications.

Some listings have build-date distinctions. The 2018 Sportsman 570 SP is split at 12/15/17, while the Touring 570 EFI EPS fitment is split at 8/29/17. Those cutoffs can make a broad model name insufficient for confirming fit. Match your machine’s exact year, trim, and build date against the applicable listing before ordering, the product information does not establish universal Polaris fitment.

Usage tips

Before starting, compare the parts you need with the kit contents and confirm you are rebuilding a single A-arm. Keeping the removed components organized can help when identifying where the included shims and spacers belong during reassembly. For example, if you are servicing one arm after finding worn bearings or bushings, this kit groups the listed rebuild pieces in one package instead of requiring you to source each type separately.

The product details do not specify installation instructions, tools, or service procedures. Use the repair guidance for your exact vehicle rather than assuming the same steps apply across every ACE and Sportsman configuration. If your repair calls for a complete replacement arm, this component kit is a different approach and may not cover that need.

Questions before you buy

How many A-arms does the kit rebuild? It is specified for rebuilding one A-arm. The description does not say that it includes enough parts for both sides.

What components are included? The stated contents are bearings, bushings, bearing shafts, seals, shims, and spacers.

Does it fit every Polaris ACE or Sportsman? No universal fit is stated. The fitment list names specific models, years, trims, and, for some applications, build-date cutoffs.

Buying verdict

Choose this kit when your Polaris matches a listed application and your repair calls for rebuilding one A-arm with the included bearing and bushing components. Its useful distinction is the bundled set of rebuild parts, rather than a complete arm replacement. Skip it if you need a full assembly, parts for more than one arm, or cannot confirm your machine against the detailed year and build-date fitment.
