Used OEM parts for the Kawasaki Mule 3010 and Mule 4010 (KAF620/KAF950) are available at Sun Coast Cycle Sports. The Mule 3010 (2001-2008) and Mule 4010 (2009-present) represent the evolution of Kawasaki's mid-size utility vehicle platform, offering liquid-cooled V-twin engines with CVT transmissions, selectable 2WD/4WD, and tilting steel cargo beds for farm, ranch, and commercial work applications. Every Mule part we carry is individually inspected, photographed, and shipped from Florida.
Mule 3010 and 4010 models and parts compatibility
| Model | Years | Engine | Key details |
|---|
| Mule 3010 (KAF620) | 2001-2008 | 617cc liquid-cooled V-twin, carbureted | Successor to Mule 2510. 2WD and 4x4 variants. Transporter model with extended bed. |
| Mule 4010 (KAF620) | 2009-present | 617cc liquid-cooled V-twin, fuel-injected | Updated from Mule 3010. Switch to fuel injection. 2WD and 4x4 variants. Trans model with extended bed. |
The Mule 3010 and 4010 share the same fundamental 617cc V-twin engine architecture (KAF620 platform). The major compatibility dividing line is the switch from carburetion (3010) to fuel injection (4010) in 2009, which changed the fuel delivery system, ECU, and related electrical components. Engine internals (pistons, crankshaft, transmission) are broadly shared between the 3010 and 4010.
Within each model, parts interchange freely across model years: all 2001-2008 Mule 3010 components are interchangeable, and all 2009+ Mule 4010 components are interchangeable. The Transporter variants (extended bed) share engine and drivetrain parts with standard-bed models but have unique bed and frame-extension components.
Neither the 3010 nor 4010 shares parts with the Mule Pro-FXT/DXT, which uses a different 812cc three-cylinder engine in a larger chassis.
Common Mule 3010/4010 failure points and replacement parts
CVT belt wear: The CVT drive belt is the primary consumable. Utility use with heavy loads, towing, and low-speed crawling accelerates wear. Belt replacements are the highest-volume parts request.
Carburetor issues (3010): The Mule 3010's carburetors are prone to varnish buildup during storage and require periodic cleaning and synchronization. Carburetor rebuild kits are the most common 3010-specific maintenance item.
Fuel injection sensors (4010): Higher-hour 4010 units can develop intermittent sensor faults. Throttle position sensors, intake air sensors, and fuel injectors are periodic replacement items.
Front differential (4x4 models): The selectable 4WD system develops seal leaks and engagement issues with heavy use. Front differential seals, actuator components, and related hardware are common maintenance items.
Cargo bed and frame wear: The tilting cargo bed's pivot hardware, latches, and bed floor wear with years of loading and unloading. Bed components and chassis hardware are steady replacement items on working machines.

Frequently asked questions
Q: Are Mule 3010 and 4010 parts interchangeable?
Engine internals are broadly shared. The primary compatibility break is the fuel delivery system: the 3010 is carbureted and the 4010 is fuel-injected. Frame, bodywork, and many chassis components are similar but should be verified, as Kawasaki made refinements with the 2009 update.
Q: Does the Mule 3010/4010 share parts with the Mule Pro-FXT?
No. The Mule Pro-FXT/DXT uses a larger 812cc three-cylinder engine in a full-size chassis. Different engine, different frame, different bodywork. No meaningful parts interchange exists between the 3010/4010 and Pro-FXT platforms.
