S&S Cycle Milwaukee 8 HPT496 Camshafts

S&S Cycle Milwaukee 8 HPT496 camshafts are high performance, bolt-in cams designed for 2017-later Harley-Davidson® Milwaukee-Eight (M8) engines. They deliver a wide power curve with high horsepower and torque, often achieving roughly 130 square (hp/tq) on performance builds. Known for their aggressive idle, these cams work well with stock-compression engines up to 128 cu. in., offering significant performance gains.

Key details:

* Performance: Known for producing massive mid-range to high RPM power while retaining strong torque, with recorded gains of nearly 30 hp on 117 cu. in. engines
* Design: Features a 0.485 in. lift and optimized durations, specifically with less exhaust duration than the S&S 475 to improve tuning flexibility and performance with varied exhaust systems
* Bolt-in convenience: Compatible with stock valve springs, tappets, and rocker arms for easy installation
* Sound: Renowned for a very aggressive, deep rumble, often described as "sounding like an animal"
* Versatility: Works great in stock 107/114 cu. in. engines, but is robust enough for larger 124/128 cu. in. builds, functioning well with up to 11:1 compression
* S&S Cycle HPT496 cams are available in both chain-drive and gear-drive options. They're designed to be a durable upgrade, with testing showing higher surface hardness (56.3 Rockwell C) compared to stock cams (49.7 Rockwell C)
