Made from ARP2000 material and rated to 220,000 psi, ARP cylinder head studs not only offer superior clamp loads over cylinder head bolts, they provide proper alignment of the head and gasket with more accurate and consistent torque loading. Bolts will actually twist while torquing to proper spec, greatly reducing their ability to hold true.

BC valves are one piece design with a friction welded Stellite tip for the best possible performance. Every valve is made from premium grade, heat resistant stainless steel material to insure reliability with high boost and/or high rpm applications. The undercut stem above the head area not only reduces overall weight for extended rpm potential, but also significantly improves air/fuel flow in and out of the combustion chamber. Every valve is fully machined and features a swirl polished finis...

Polaris XP Turbo - Carrillo Connecting rods were founded by Fred Carrillo in 1963. Fred approached the challenges of manufacturing with the idea of no compromise. He knew the never ending quest for speed would require the same desire in component manufacturing. This Carrillo philosophy is as evident today as it was at Carrillo’s conception in 1963. Quality and pride go hand-in-hand at CP-Carrillo. Manufacturing a CP-Carrillo rod is much more than cutting a forging, meeting production goals a...
