The Polaris ATP (All Terrain Pickup) was a short-lived utility ATV with an integrated rear cargo bed, produced from 2004 through 2005 in 330cc and 500cc versions. The ATP combined the traditional ATV riding position with a small tilting cargo bed behind the rider, creating a hybrid between a standard utility quad and a small UTV. The ATP 330 uses a 329cc air/oil-cooled single-cylinder engine (shared with the Trail Boss 330 and Magnum 330 family), while the ATP 500 uses a 499cc engine (shared with the Sportsman 500 family). Both use PVT automatic transmissions. Sun Coast carries used ATP parts from salvage donors that come through our Florida facility, with each piece inspected, photographed, and assigned its own SKU.
Polaris ATP generation and parts compatibility
| Model | Years | Engine | Key notes |
|---|
| ATP 330 4x4 | 2004-2005 | 329cc air/oil-cooled 4-stroke single, carbureted | Shares engine with Trail Boss 330, Magnum 330. Integrated tilting cargo bed. |
| ATP 500 HO 4x4 | 2004-2005 | 499cc liquid-cooled 4-stroke single, carbureted | Shares engine with Sportsman 500. Higher output "HO" version. Integrated cargo bed. |
The ATP was produced for only two model years before being discontinued. The ATP 330 shares its 329cc engine and many drivetrain components with the Trail Boss 330, Magnum 330, and Hawkeye 300 family. The ATP 500 shares its 499cc engine with the Sportsman 500 and Scrambler 500 of the same era. In both cases, some engine internals and drivetrain components cross between the ATP and its platform siblings. However, the ATP's defining feature, the integrated tilting cargo bed and the frame section that supports it, is unique to the ATP and has no parts relationship with any other Polaris model. Front bodywork and some suspension components may interchange with contemporaneous Sportsman models, but the rear frame, bed, and associated hardware are ATP-specific.
Common Polaris ATP failure points and replacement parts
Carburetor degradation (both models): Both ATP models are carbureted, and ethanol-related fuel system deterioration is the most common issue on any stored example. Gummed carburetors and degraded fuel lines require attention before riding any ATP that has sat.
Cargo bed hardware and hinges: The ATP's tilting cargo bed uses hinges, latches, and a support strut that wear with use and can corrode. Since the bed is the unique selling point of the ATP platform, these components see heavy use on working machines.
PVT belt and clutch wear: Standard Polaris ATV wear items. The ATP, used as a working machine, often sees heavier loads than recreational ATVs, which accelerates belt wear.
Cooling system (ATP 500): The liquid-cooled 500 engine relies on a radiator exposed to trail debris. Overheating under load is a common complaint if the radiator fins are clogged or the water pump is worn.

Frequently asked questions
Q: Does the ATP share parts with the Sportsman or Trail Boss
The ATP 330 shares its engine with the Trail Boss 330, Magnum 330, and related models. The ATP 500 shares its engine with the Sportsman 500 family. Some engine internals and front-end components cross between these platforms. However, the ATP's rear frame, cargo bed, and bed-specific hardware are unique to the ATP and have no counterpart in any other Polaris model.
Q: Why was the ATP discontinued
The ATP was produced for only two model years (2004-2005). Polaris shifted its utility-with-cargo focus to the Ranger side-by-side platform, which offered more cargo capacity and passenger seating in a more practical package. The ATP remains a niche collector item among Polaris enthusiasts.
