Arlen Ness Radius Oil Pressure Gauge Kit For Harley Twin Cam 1999-2017

Arlen Ness Radius Oil Pressure Gauge Kit For Harley Twin Cam 1999-2017 Arlen Ness Radius Oil Pressure Gauge Kit: Essential Monitoring for Twin Cam Models Take the guesswork out of your engine’s vitals with the Arlen Ness Radius Oil Pressure Gauge Kit. Specifically engineered for 1999–2017 Harley-Davidson Twin Cam engines, this kit is a vital Harley-Davidson maintenance upgrade for the modern V-Twin rider. While factory dash lights only warn you when pressure is dangerously low, this mechanical gauge provides a real-time, numerical readout of your oiling system’s performance. Whether you are navigating heavy traffic on a Street Glide or touring the coast on a Heritage Softail, Arlen Ness provides the data you need to ensure your V-Twin performance remains at its peak. Signature Radius Billet Design Arlen Ness is world-renowned for transforming functional components into works of art. This kit features a precision-machined billet aluminum housing with the iconic “Radius” styling, finished in a mirror-like show chrome. The bracket is designed to mount seamlessly to the rear rocker box, positioning the gauge perfectly for a quick glance without distracting you from the road. This chassis styling upgrade replaces the industrial look of stock hardware with a custom, polished aesthetic that flows with the lines of your Road King, Dyna, or Softail. Liquid-Filled Accuracy and Durability The high-vibration environment of a large-displacement Twin Cam 88, 96, or 103 engine can make standard gauges difficult to read. The Arlen Ness gauge is liquid-filled with high-viscosity silicone to dampen internal movement and protect the delicate internals. This dampening effect keeps the needle rock-steady, providing a flicker-free reading even at highway speeds. The easy-to-read gauge face is protected by a weather-sealed lens, ensuring chassis reliability and visibility in all riding conditions, from desert heat to coastal rain. High-Pressure Stainless Steel Plumbing Reliability is built into every detail of this Arlen Ness oil pressure kit. The assembly includes a braided stainless steel oil line that is far superior to the plastic tubing found in entry-level kits. This high-tensile line is heat-resistant and prevents expansion under pressure, ensuring the most accurate reading reaches the gauge. The kit comes complete with all necessary fittings and chrome mounting hardware, providing a professional “bolt-on” Stage 1 styling upgrade that requires no permanent engine modifications.

The Legacy of Arlen Ness Custom Parts For over five decades, Arlen Ness has been a pioneer in the aftermarket Harley parts industry. Their components are trusted by professional builders worldwide for their perfect balance of form and function. By choosing the Radius Oil Pressure Gauge, you are adding a piece of motorcycle history to your build. Arlen Ness products are designed to withstand the test of time, ensuring that your custom Harley project remains as reliable as it is beautiful. Installation and Care Tips For a leak-free installation, we recommend using a small amount of high-quality thread sealant on the oil line fittings. This kit is the perfect companion to a Harley-Davidson service interval, such as an oil and filter change. To keep the chrome finish looking its best against the heat of the engine, wipe the housing down periodically with a soft cloth and a non-abrasive chrome polish. Ensure the oil line is routed away from direct contact with cylinder fins to maintain maximum airflow and cooling. Monitor your engine with confidence and style.
