MaxHiflo VTTOCK14 Complete Engine Oil Change Kit for V-Twin Harley Twin Cam – 6-Quart

All-in-one VTTOCK14 Kit for V-Twin Harleys

The MaxHiflo VTTOCK14 Complete Engine Oil Change Kit is designed to simplify maintenance for Harley-Davidson Twin Cam engines from 2000 to 2015. This four‑part bundle combines engine oil, primary fluid, transmission oil, and a premium filter in a single ready-to-use package, helping you complete routine service with confidence and ease.

Engine oil with advanced protection

Maxima V-Twin Full Synthetic is an ester-based formula that helps manage operating temperatures, reduces wear, and strengthens the oil film. Its regenerative polymer system resists shear and heat breakdown, supporting viscosity retention under demanding riding conditions. The result can be a steadier ride and smoother starts in hot weather.

Key points include:

• Lower temperatures and enhanced film strength
• Extended protection across severe climates
• Ultra-clean additives to help keep the engine clean and sludge-free

Gear and primary fluids built for performance

The kit includes Maxima V-Twin Heavy-Duty Transmission & Gear Oil (85W-140) and Maxima V-Twin Primary Oil, both mineral-based formulations designed for 4-, 5-, and 6-speed gear boxes and primary chaincases. You may notice smoother shifts under peak loads and RPMs, with additives that resist viscosity loss and wear while maintaining lubrication in high-demand riding.

• High film strength and EP additives for reliable shifts
• Detergents to protect gears from wear and deposits
• Coordinated mineral basestocks for predictable performance

Premium filtration with easy service

The kit pairs a Black HiFloFiltro HF171BRC Premium Oil Filter with the rest of the package. Tests indicate HiFloFiltro filters offer longer service life than OE and many competitors, and the 17mm cross-drilled nut supports easy installation, removal, and lock-wiring for quick, clean changes.

• Potentially longer service life than OE filters
• Cross-drilled nut for easy wrench access and secure fastening
• Designed for Harley Twin Cam configurations and multi-fluid compatibility
