Perform a comprehensive, professional grade fluid maintenance sweep on your machine with the definitive Maxima V-Twin 3-Fluid Scheduled Service Package. Put together explicitly to overhaul all three isolated oil cavities of traditional air-cooled configurations in a single shop pass, this high-performance bundle replaces your engine oil, transmission gear lubricant, primary chaincase fluid, and oil filter. Combining Maxima’s highly shear-stable petroleum matrices with a premium 17-micron structural HiFloFiltro filter, this package delivers continuous anti-wear buffering across heavy touring loads and intense summer traffic heat intervals.
- Complete 3-Cavity Solution Kit: Removes purchasing friction by supplying the exact fluid weights needed to refresh the motor, transmission, and primary case.
- Maxima V-Twin 20W-50 Mineral Power: Formulated with advanced anti-wear polymer treatments and industry-leading zinc/phosphorus (ZDDP) levels to preserve high-load valvetrain parameters.
- Specialized V-Twin Primary Oil (40-04901): High-grade 80W formulation reduces chain drag, prevents wet-clutch slippage under load, and minimizes clutch chatter.
- Heavy Duty Trans Gear Oil (40-01901): Robust 85W-140 weight cushions gear teeth interfaces to significantly dampen mechanical transmission clunk and ease neutral hunting.
- HiFloFiltro HF171B Black Premium Filter: Constructed using top-tier blended power-flow filtering media to deliver continuous filtration down to 17 microns without limiting high-frequency oil pressure lines.
💡 Critical Fitment & Capacity Notice:
This 6-quart configuration bundle is optimized specifically for Harley-Davidson Twin Cam engines (Big Twin 1999–2017). While the fluid capacities cover standard dry-fill limits across most Touring, Softail, and Dyna configurations, always check your factory manual parameters--some later generation 103ci/110ci oil pans or oversized primary setups may require a fractional top-off amount. Note: This kit features a Black filter canister finish.Verified Vehicle Fitment Application GuideMakeEngine Platform / Sub-Family GroupModel Year Fitment RangeHARLEY-DAVIDSONTwin Cam 88 / 88B (Flange & Spigot Mount Mounts)1999 - 2006HARLEY-DAVIDSONTwin Cam 96 / 96B (Touring, Softail, Dyna)2007 - 2011HARLEY-DAVIDSONTwin Cam 103 / 103B High Output (Electra Glide, Road King, Street Glide, etc.)2012 - 2017HARLEY-DAVIDSONTwin Cam 110 / 110B Screamin\' Eagle / CVO Models2007 - 2017
Fitment Warning: This package is dedicated to the Twin Cam family. It will NOT fit older Evolution (Evo) engines due to filter thread differences, nor will it provide enough fluid capacity for modern 4-cavity or 2017+ Milwaukee-Eight (M8) platforms without adding individual quarts.
