CHRIS Rivas has made his Rocket Signature Series chain drive Rocket Cams available through Drag Specialties. The cams, designed by Chris himself, are finished in black oxide and are available with or without ‘Easy Start’ centrifugal compression release system for easy starting even with large displacement, high compression motors. The Easy Start system is licensed from S&S Cycle by Rivas.
The Rocket 574 cams for all ‘07-‘15 Twin Cam and ‘06 Dyna models are designed to be used with stock valve springs, and are said to make best power, with peak performance at 1,500 to 5,800rpm, when used in combination with a free-flowing air cleaner and performance exhaust.
Completing the Rocket cams range from Chris Rivas are the Rocker 634, again for use with ‘07-‘15 Twin Cam and ‘06 Dyna models, they are said to provide peak performance at 2,200 to 6,200rpm. These cams have been designed for modified engines 107ci or larger with compression ratios 11.25:1 and higher, .650in valve springs, and a free-flow air cleaner and a high-performance exhaust.
