So these 585 springs are good for up to .650 lift??? That's what I'm getting from these previously answered questions.
By Anon.
Yes, you can use these springs with cams that have up to 0.650" of lift. They're far more durable than stock and, by many accounts, help quiet down valve noise, especially when running cams that are closer to stock lift. Either way, they're most certainly an improvement over the OEM Harley-Davidson valve springs!
Do you need this up grade kit for MR 585C cams S&S say it a bolt in with stock heads is good for 590 lift with stock heads
By Lee C.
While it's not required for every set of Harley-Davidson cams on the market, it's never a bad idea to to upgrade the valve springs anytime you're opening up valve lift. These valve springs are suitable for lifts up to 0.650" - so the 585C cams you're working with are well within the specification for these S&S engine valve springs to handle.
Do these come with new valve seals and are these a good match for S&S 585c cams?
By Ss
Yes, the valve guide seals are indeed included. And, as the 585C cams are indeed suitable for use with these valve springs. In fact, these particular springs can be used with any cam kit with up to a .650" lift.
I need valve springs for an 88 cubic inch motor with an S&S 510 gear drive kit. Will these fit?
By Alan
S&S 510 gear drive cams don't require you to replace the stock valve springs as the lift is only .510" for that motor. If you want some springs to provide positive valve seating pressure while also allowing room for further modification up to .650" valve lift, the springs we have here are perfect for your needs. S&S valves include top collars, bottom collars, springs, shims and valve keepers and will install directly to the OEM valves on your 88" engine.
