Feuling OE+ Hydraulic Cam Chain Conversion Camchest Kits For Harley Twin Cam 1999-2006

Feuling OE+ Conversion: Modernizing the Classic Twin Cam 88 & 95

The Feuling OE+ Hydraulic Cam Chain Conversion Camchest Kit for 1999-2006 Harley models represents the 2026 pinnacle of preventative maintenance and performance tuning. For years, owners of early Twin Cams (except 2006 Dynas) have lived with the risk of “tensioner failure,” where the factory spring-loaded pads wear down and send plastic debris through the oiling system. Feuling has engineered the definitive 2026 solution by adapting the high-velocity 2007-up hydraulic system to fit the early engine cases. This conversion uses engine oil pressure to maintain consistent, light tension on the cam chains, which significantly extends pad life and results in a much quieter valvetrain. For the rider seeking secure, industrial-strength utility, this kit is not just an upgrade—it is an essential insurance policy for your motorcycle’s longevity.

Superior Billet Fabrication and Enhanced Lubrication

What sets the Feuling OE+ conversion apart in the 2026 marketplace is the integration of the **OE+ High-Volume Oiling System**. This kit includes a cam plate machined from 6061 billet aluminum, which is far more rigid than the porous factory cast plates. This rigidity ensures that your cam bearings remain perfectly aligned even under the stress of a Stage 2 build. Coupled with a high-flow gerotor oil pump, the system delivers 20% more oil pressure to the top end and 20% more scavenging capacity to the crankcase. This combination dramatically lowers engine temperatures, a vital benefit during the intense heat of the 2026 summer riding season. Every component—from the precision-ground chains to the hydraulic cylinders—is hand-inspected and dyno-verified to ensure a flawless, leak-free installation that restores factory-fresh performance to your Twin Cam 88 or 95.

Expert Installation & Performance Advice

As specialists in Twin Cam valvetrain architecture, we recommend this conversion kit for any bike with over 20,000 miles. Pro Tip: This kit is designed to work with “conversion” style camshafts. If you are keeping your early-style cams, ensure you select the appropriate kit or upgrade to Andrews or S&S conversion cams for a perfect 2026 fit. Installation Note: Always “center” the oil pump during the install by rotating the engine by hand while the mounting bolts are snug; this prevents internal friction and ensures maximum pump life. Maintenance Note: Use a high-quality synthetic 20W-50 oil and a premium high-flow filter to take full advantage of the increased scavenging rates. Safety Note: Before installing, check your crankcase run-out; Feuling recommends a maximum of .003″ to ensure the long-term integrity of the billet plate and precision pump during your 2026 tours.

Cam Info:

• 525 Cams are a real workhorse, designed to increase torque band width and increase fuel economy. Great bolt in camshaft upgrade for stock 88 & 96 engines also performs very well in 103 strokers. Produces strong low and mid-range power with a linear horsepower and torque curve. Can be used with factory valve springs, pushrods and lifters. Increases throttle response and eases starting. Will also respond well to increased compression and cylinder head work. RPM 1,750-5,500
• 543 Cams are the freeway flyer, a great camshaft for those who want more top end power than our 525 cams without sacrificing low end torque. Extremely smooth cam lobe layout maintains quiet valvetrain and produces the smoothest cruise power band available. Excellent bolt in camshaft for stock to mild 96 and 103 engines and works well in 88 & 95 engines. This cam is easy starting, increases throttle response and fuel mileage. Responds well to increased compression ratio, performance exhaust and a high flow air cleaner. Performance valve springs are required on 99-04 engines and performance pushrods and lifters are recommended but not required. RPM 1,900-5,900
• 574 Cams have a wicked power band for modified engines and an excellent bolt in for stock 96, 103 & 110 engines. This is a great all-around camshaft with solid low-end performance and mind blowing mid and top end power. Extremely smooth cam lobe design creates a very smooth valve-train motion. Responds very well to modified cylinder heads, increased compression ratio, performance exhaust and intake systems. Performance valve springs are required on 99-04 engines and performance pushrods and lifters are recommended. RPM 2,100-6,300
