Used 400 500 570 ETX Midsize Parts

Used parts for Polaris Ranger 400, 500, 570 ETX, and Midsize models are carried at Sun Coast Cycle Sports. This category covers the compact Ranger UTVs designed to fit in a standard full-size pickup bed for easy transport. These midsize Rangers use single-cylinder engines ranging from 400cc to 570cc, offering lighter weight, easier maneuverability, and lower cost than the full-size Ranger 800/900/1000 models while still providing genuine work utility. Our Florida technicians evaluate each midsize Ranger donor, photograph parts under unique SKUs, and ship free across the continental U.S.

The midsize Ranger family uses single-cylinder engines that share architecture with the Sportsman ATV lineup. The Ranger 500's engine is shared with the Sportsman 500, and the Ranger 570's ProStar engine is shared with the Sportsman 570, RZR 570, and ACE 570. Engine internals cross over between these Polaris platforms within the same displacement and fuel system generation.

Midsize Ranger chassis dimensions are significantly smaller than full-size Rangers (700/800/900/1000). Body panels, cab components, cargo boxes, and most accessories do NOT interchange between midsize and full-size Ranger models. Within the midsize family, some chassis and body components interchange across displacement variants of the same era, but verify by part number as Polaris updated dimensions between generations.

The Ranger 570 full-size (2015+) is a different vehicle from the midsize 570. The full-size 570 uses the same ProStar engine in a full-size Ranger chassis with greater payload and towing capacity. Full-size and midsize 570 body and chassis parts do NOT interchange despite sharing the same engine.

Common Ranger Midsize failure points and replacement parts

Drive belt wear: The midsize Rangers' lower power output provides good belt life under normal conditions. Heavy hauling for the chassis size (overloading) is the primary cause of premature belt wear.

Carburetor fouling (Ranger 400 and carbureted 500): Carbureted midsize Rangers are susceptible to pilot jet clogging and float needle sticking during extended storage. Fuel stabilizer and carburetor draining before storage prevent most starting issues.

Voltage regulator failure: The charging system on older midsize Rangers can develop regulator failures. Symptoms include dead batteries, dim lights, or overcharging. Aftermarket replacements with improved thermal management are available.

Cargo box capacity limitations: The midsize Ranger's compact chassis limits payload capacity compared to full-size models. Overloading the cargo box stresses the frame, suspension, and drivetrain beyond design limits, leading to premature component failure.

CV boot tears: Same vulnerability as all Polaris AWD vehicles. Trail debris tears CV boots, requiring prompt replacement to protect the CV joints.

Frequently asked questions

Q: Will full-size Ranger parts fit a midsize Ranger?

No. The midsize and full-size Ranger platforms use different chassis dimensions, body panels, cargo boxes, and most accessories. The midsize is designed to fit in a pickup bed for transport, while the full-size is a significantly larger vehicle. Engine parts may cross over if both use the same displacement (e.g., Ranger 500 midsize and Sportsman 500 share engine internals), but chassis components are platform-specific.

Q: Does the midsize Ranger 570 share its engine with the Sportsman 570?

Yes. The Ranger 570, Sportsman 570, RZR 570, and ACE 570 all use the same 567cc ProStar single-cylinder engine. Engine internals interchange across all four platforms. ECU calibration, exhaust, and mounting hardware are vehicle-specific.

Q: Is the Ranger 570 midsize the same as the Ranger 570 full-size?

No. Both use the same 567cc ProStar engine, but they are mounted in different chassis. The midsize 570 has a compact chassis designed to fit in a pickup bed, with lower payload and towing capacity. The full-size 570 uses a larger chassis with greater work capability. Body panels, cab, and cargo box components do NOT interchange between the two. Engine parts are shared.
