i have an old 75-5550 helix from black magic kickin around from my old 440...just wondering what this will do in my 03 F7 sp. will it work and what will it do?
Thats a billet,CNCed, anodized helix with lifetime warranty.
It has more start and finish angle than the stock 53/51.
Should give you a better starting pull out of the hole, more aggressive slift and better belt grip on topend.
