Reaper 543 Conversion Cams / Early Twin Cam

Features of the Reaper 543 Conversion Cams

• Conversion Cams allow you to update the mechanical-style tensioner systems to the new late-style hydraulic tensioner chain drive system; these kits utilize conversion Reaper camshafts which have '99-'06 inner-cam journals matched with '07-'17 outer-cam journals, allowing the use of the '07-'17 cam plate and hydraulic chain drive tensioner system; hydraulic chain drive components purchased separately. Options include pt# 9251060 and 9251061.
• Offers more power than the 525 cams without sacrificing low end torque
• Extremely smooth cam lobe layout maintains quiet valve train and produces the smoothest cruise power band available
• Excellent bolt-in camshaft for stock to mid 96" and 103" engines and works well in 88" and 96" engines
• Cam is easy starting, increases throttle response and fuel mileage
• Responds well to increased compression ratio, performance exhaust and a high-flow air cleaner
• 1900-6000 RPM power range
