Chris Rivas Signature Series

Chris Rivas Signature Series chain drive Rocket Cams

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.

Created for use in ‘07-‘15 Twin Cam and ‘06 Dyna models, Rocket 584 cams are claimed to deliver constant power while reducing detonation. Once again they are recommended for use with a free-flowing air cleaner and performance exhaust and additionally with ported heads and a minimum 10.0:1 compression ratio. The high lift cams are best suited to upgraded engines of 103ci or 107ci displacement.
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.
