Starter with Drive for Polaris 300/400 Models - Reliable Replacement

In this review of the Starter with Drive for Polaris 300/400 models, the bottom line is simple: this unit is for riders and DIY mechanics who need a direct-fit replacement starter that restores reliable electric starting to a range of Polaris ATVs. The reviewer found the starter's 12V, 1.4KW PMDD design and included drive Bendix to be the single biggest reason to choose this part, because it matches original engagement and power characteristics for 9-tooth CW applications and ships ready for installation. The review focuses on fitment, build match to OEM part numbers, and what to expect during installation.

Key Features

• Direct fit parameters: The starter is a 12V, 1.4KW PMDD unit with 9 teeth and clockwise rotation, so it matches common OEM starter characteristics for the listed Polaris models.
• Broad compatibility: It is compatible with many Polaris models including Scrambler, Trail Boss, Xplorer, Trail Blazer and Sport/Sportsman 378cc/400 engines, reducing the risk of a wrong purchase when fitment is confirmed.
• OEM cross references: The part lists multiple OEM numbers such as SM1329850 and 308539 variants, helping owners verify compatibility with factory service parts lists.
• Complete package: The kit includes the starter and a drive Bendix so you receive the engagement gear needed for installation without hunting for extra parts.
• Simple replacement: The PMDD construction and matching rotation make installation straightforward for mechanically inclined users replacing a failed stock starter.

Who It's For

This starter is aimed at Polaris ATV owners and independent mechanics who need a dependable replacement for failed or weak starters on mid-size machines. It suits owners of Scrambler, Trail Boss, Xplorer, Trail Blazer, Big Boss and Sport/Sportsman 378cc or 400 machines when the engine uses a 9-tooth CW starter. The included Bendix is helpful for someone doing the swap at home or in a small shop.

Those who should look elsewhere are riders unsure of their exact starter tooth count, rotation, or voltage, or owners of models outside the listed fitment. Also, riders who prefer dealer-installed OEM parts for warranty continuity may want to consult their service provider first.
