• Update old mechanical-style cams and tensioners to new-style hydraulic tensioner system
• Produce more power and torque increasing cranking compression, improving throttle response, acceleration and fuel mileage
• Utilize 99-06 inner cam journals with 07-13 outer cam journals and chain sprockets allowing use of 07-13 camplates, oil pump and hydraulic chain tensioners and chain system (parts not included, must be purchased separately)
• Dyno proven and track tested
• Made in the U.S.A.

543 CAMS

• The 'Freeway Flyer', a great camshaft for those who want more top- end power than the 525 cam without sacrificing low end torque
• Performance valve springs are required on 99-04 engines and performance pushrods and lifters are recommended but not required
• Cam is easy starting, increases throttle response and fuel mileage. Responds well to increased compression ratio, performance exhaust and a high-flow air cleaner
• Extremely smooth cam lobe layout maintains quiet valve-train and produces the smoothest cruise power band available
• 1,900 - 6,000 rpm power range
• Excellent bolt-in camshaft for stock to mild 96" and 103" engines and works well in 88" and 95" engines
