510G: Designed as a bolt-in cam for 88", 95" and 96" engines with compression ratios below 9.7:1 and is primarily intended for use with stock, un-ported heads. 3000-5500 rpm. Bolt-in overall.
551G: Designed for engines with 96" to 106" and 9:1 to 9:9 compression. This bolt-in cam set is designed for stock or mildly modified Touring bikes. 551 cams are not recommended for compression ratios of 10:1 or greater. Greatly improves low-end and mid-range torque, strongest from idle to 4000 rpm
570G: Designed for 88" to 103" engines with compression ratios between 9:1 and 10:1. This cam will provide a nice power increase across the entire power band. 3200-5700 rpm. Excellent bolt-in for overall power on 103"
583G: Optimized for use in the Softail^® and Dyna^® lines, this cam makes horsepower and torque that you can feel all the way through the rpm range, making the most power right where you need it. 1500-5000 rpm
585G: Designed for 88" to 95" engines with compression ratios from 9.7:1 to 10.5:1 and 100" to 124" engines from 9:1 to 10:1 compression.
