Roller Rockers .

[Fusion]

Hi Guys , I'm thinking of getting my first set of roller rockers for a black (VK) 308 and what are the benefits of using roller rockers to the standard rockers ? Never used rollers before . so a novice on this part . Thanks

Strength is the most common reason for fitting roller rockers but you also have the advantage of the roller tip not side loading the valve stem so the guides and seats last much longer.
Rollers typically have a better ratio than factory pressed steel arms so power gains are common.
Adjustability is another reason to fit them as they allow you to compensate for different valve lengths or set clearance on solid lifters.
