Get your Proform parts in Canada from your Proform North American Dealer Marken Performance 1-888-401-1362
Sick and tired of re-tightening your header bolts? Proform has come up with an amazing pair of pre-installed washers available now thru Marken Performance, Kitchener. When the bolt is tightened, the washers engage the bolt head and the header flange. During vibration the bolt will try to loosen itself, but cannot because the step shaped teeth between the washers are taller than the bolt can stretch.
