The crank drive of your tuned V8 or V10 has to endure a lot if you experience an extreme increase in performance, e.g. go for a turbo conversion. Here enormous forces and temperatures act, which the series bearing shells are unfortunately not up to. So that the bearings continue to work perfectly even at high speeds, together with boost pressure, you should use our special bearing shells. This means that a higher engine speed with boost pressure is not a problem. So you can enjoy the full performance without worrying about guzzling bearings or lack of oil supply! features: Tri-metal coating Higher engine speed possible Stable for boost pressures up to 2 bar High temperature resistance Heat treated material High strength steel Quality and workmanship at the highest level The kit includes 12 bearing shells for the V10 and 10 shells for the V8 picture similar Manufacturer Information about the manufacturer BAR-TEK BAR-TEK Motorsport GmbH Im Rauschen Auel 3, 51491 Overath-Brombach, Germany info@bar-tek.com
