Super Light Design and Competition Proven! Rotating Assembly with SRP Professional Series Pistons
Scat rotating assembly component parts are designed for the ultimate in performance. They take the ''guess work'' out of engine assemblies, just wash, Q.C. and assemble. The heart of this assembly is the Superlight design crankshaft. This race crank starts by being precision ground and nitrided hardened for superior wear resistance. Key features of the Superlight crankshaft are the aero wing counterweights, pendulum undercut counter weights, rod journals are bridge for increased strength and lightening holes in all rod journals, large radius on all journals, straight shot and chamfered oil holes make this crankshaft super light and the racers top choice!
This Assembly features Scat Q-Lite H-Beam or Ultra Q-Lite Stroker H-Beam 4340 forged connecting rods. They are a bushed pin design. They are shipped 100% ready to install with ARP cap screws and feature special doweled cap and profiled clearance. The Formula ''1'' style lightening hole which reduces big-end weight, but does not compromise strength.
The pistons are SRP Professional Series which are an advanced, lightweight FSR forging that eliminates stress concentrations for superior strength, Up to 20% lighter than traditional equivalent, High-silicon 4032 aluminum alloy for reduced piston-to-wall clearance and quiet operation, Accumulator grooves for improved ring seal, Designed for normally aspirated or moderate forced induction/nitrous applications, and now includes high performance skirt coating! Lightweight, low friction metric piston ring package is included. It features 1.2mm top ring, 1.5mm Napier 2nd ring, 3.0mm standard tension oil ring. The Napier 2nd ring was chosen for improved oil control. Minimal filing required. High quality 2.250'' piston pins further reduces reciprocating weight. Carbon steel wire locks included.
Rod and main bearings are included with each rotating assembly. The bearings are chosen by Scat from the most respected names in the business such as Clevite, King, and Federal Mogul, that best works with each premium crankshaft and rotating assembly.
