Maddog Big Twin Performance began as a result of the owner of traditional automotive engine parts warehouse wondering why folks were willing to pay $450 for a set of 4 roller rockers for a Harley, when they could get 16 Crane gold roller rockers for their Chevy or Ford for less than $300. It just didn't seem to make much sense. We at BTP took that idea and ran with it, producing not only roller rockers for Evo/Twin Cams, but listening to the needs of the Harley community and adding Shovel roller rockers to the family.   Our motto "Harley Performance at affordable pricing" will continue, and this means two things to the Harley owner community. We will always be noticeably lower in price on comparable parts to the 'big boys', and we will keep the quality up to the highest level.
