KING has proven itself in the sport compact and domestic market place for years (Rally, GT Series, Land Speed Record engines and more) and since it's becoming painfully evident that ACL has had a supply shortage for the BP Main bearings, we've done some research that lead us to a solution we wish we'd come across sooner. After discussion with a world renown certified lubrication specialist and an oil monitoring analyst friend of ours and our Machine shop, KING's XP series is a line of bearings that could offer a level of protection we couldn't achieve elsewhere.
King Racing’s XP series features pMax Black™, a unique tri-metal structure that is 24% harder than any other conventional tri-metal race bearing - a PERFECT fit for the BP factory forged crank and a set of aftermarket forged rods.
This video is a bit intense (music) but it does a GREAT job at outlining the key differences between the KING pMax-Black tri-metal structure and that of other race bearings on the market.
We have 18 sets of these bearings on the way to us with an arrival date of 5/21/15 - 3 sets are already allocated to customers who were waiting on ACL, 3 have been ordered today and the rest will be shown as inventory on our website.
