557: Designed for Tri-Glide® models, this bolt-in cam, with it’s short duration, produces lots of useable torque.The camshaft’s stock base circle permits the use of stock pushrods.Provides massive horsepower and torque increases starting at 3000rpm and holds steady all the way to redline.3500-6000 rpm for 88" - 103" engines and 2500-5500 for larger engines.Most S&S cams have higher lift than stock and are designed to take advantage of the extra flow of ported stock heads or S&S Super Stock® heads.Due to the high lift of these cams, S&S adjustable pushrods are recommended.
Easily make 100 horses from a stock engine with S&S intake and exhaust.These cams also install just as easily as non compression release versions and require no extra parts or machining!
