Maxima V-Twin Mineral Oil Change Kit for Evolution V-Twin — Black Spin-On Filter, Shear-Stable Formula

Maxima V-Twin Mineral Oil Change Kit with Black Filter supplies the correct mineral transmission and primary oil plus a black replacement filter for 1984-and-newer Evolution Harley-Davidson V-Twin drivetrains.

This complete service kit pairs a shear-stable mineral oil formula with a matched black spin-on filter to maintain clutch feel and reduce gear and chain wear in wet-clutch Evolution systems. It’s engineered for high-load V-Twin transmissions and primary chain cases, delivering the viscosity and anti-wear properties those applications demand without synthetic additives. The kit simplifies routine maintenance by providing the right oil type and filtration in one package.

Why choose a mineral oil kit for Evolution V-Twins?

Mineral oil is specified for many older Evolution engines and V-Twin drivetrains because it provides compatible friction characteristics for wet-diaphragm clutches. The formulation focuses on preserving clutch engagement while resisting shear in gears and chains, helping maintain consistent performance between services.

• Matched viscosity suited to Evolution transmission and primary tolerances
• Friction profile designed to avoid clutch slippage
• Shear-stable to limit chain stretch and gear wear over time

What does the black filter provide during an oil change?

The included black replacement filter captures contaminants and metal particles that accumulate in the primary and transmission circuits. Replacing the filter at each service reduces abrasive wear and helps the new oil perform as intended right away.

• Spin-on black filter matched to kit oil capacity and flow
• Removes debris that can accelerate chain and gear wear
• Easy-fit design for straightforward maintenance checks

How does this kit affect clutch engagement and shifting?

Using the recommended mineral oil and fresh filter helps keep clutch friction characteristics predictable so engagement remains crisp and smooth. Proper lubrication also promotes cleaner gear meshing, which supports reliable shifting under load.

• Formula preserves wet-diaphragm clutch friction behavior
• Prevents slippage that can occur with incorrect fluids
• Supports smoother shifts by reducing gear wear and contamination

What maintenance benefits can I expect after using the kit?

Routine changes with this kit reduce long-term wear on chains and gears and maintain optimal fluid properties between services. That means fewer premature component replacements and a more consistent ride feel as the drivetrain ages.

• Extends chain life by minimizing stretch and abrasive wear
• Helps sustain gearbox tolerances and shift quality
• Simple one-kit solution for scheduled oil and filter replacement

Who is this for: Riders and home mechanics who own 1984-and-newer Harley-Davidson models equipped with wet diaphragm spring clutches and Evolution V-Twin transmissions, and who prefer the factory-recommended mineral oil specification. This kit suits anyone wanting a straightforward, OEM-compatible oil and filter change that protects clutch feel and reduces drivetrain wear—ideal for routine maintenance intervals or pre-ride servicing.
