If you are doing any performance work with your 1275cc motor you should strengthen the center main bearing cap. Of course you can also do the other two caps, we do offer straps for them also. You will have to have your cap/caps modified to accept the strap. You can have it done at your machine shop or you can send Them to us and we will do the work for you.  As you can see the straps comes with bolts and washers. Sold each.
