Melling High-Volume Oil Pumps

Melling high-volume oil pumps give you an additional 20 to 25 percent of much-needed oil volume for your performance application. For those of you who need added pressure, many pumps are supplied with a high-pressure spring (where noted). The pumps are built using a proprietary casting process, which yields maximum performance and reliability. Every Melling oil pump is completely pressure-tested, including idle and bypass pressure, before it leaves the factory. Dozens of models are available for fitment; order the pump and options needed for your vehicle.

Clevite H-Series Main Bearings

Clevite H-Series main bearings were developed primarily for NASCAR racing, but are well suited to other types of competition engines as well. They're especially good for engines that run at medium-to-high revs. They have steel backings with carefully selected overlays and a high crush factor, plus a medium level of eccentricity. H-Series bearings have enlarged chamfers at the sides for greater crank-fillet clearance and are made without flash plating for better seating. They are also available with either 180 degree or 360 degree oil grooves, as well as an extra 0.001 in. of clearance.

King XP-Series Rod Bearings

King XP-Series rod bearings feature advanced metallurgical and geometric technologies that meet extreme performance loads. They were developed for all performance applications that use forged steel aftermarket crankshafts and produce high loads for extended periods. King focuses on one product—bearings—and nothing else. Their innovative race-only Xtreme Performance Max Black Tri-Metal rod bearings have a 24 percent stronger overlay and 17 percent more fatigue strength by using a micro process called SecureBond. Built with enhanced tri-metal, King XP-Series rod bearings layer copper-lead construction with a nickel plate barrier and a lead/tin/copper Babbitt overlay over a steel backing in an adhesion process that provides superior stability and durability. King's advanced control measures hit a bull's-eye, maintaining wall thickness tolerances far tighter than their competitors—at an amazing +/- .0001 in.! XP-Series rod bearings are narrowed on the crank cheek side with increased crush height for improved bearing-to-bore contact, heat transfer, and reduced spin potential in high-rpm applications.

ACL Performance Race Series Rod Bearing Sets

ACL Performance offers Race Series rod bearing sets for a wide range of vehicles. These high performance tri-metal engine bearings are designed to withstand higher RPM conditions. They feature a high-strength overlay plate with reduced thickness for improved fatigue properties. Select the crankshaft undersize and quantity recommended for your year/make and engine application. Additional details: * Hardened steel backs on all rod bearings to improve the support of the bearing lining and assist with bearing retention in the housing. * Increased crush for improved bearing retention * Elimination of flash plating on the back of the bearings to improve heat transfer through the bearings and to maximize the grip between the bearings and its housing * Increased eccentricity to compensate for bore distortion at high RPM and to assist in the formation of hydrodynamic oil films * 3/4 in. grooved main bearings to optimize bearing load carrying surface area and oil flow to the conrod bearings * Tight consistent wall tolerances to help you maintain consistent clearances * Enlarged ID chamfers on bearing edges (where required) to accommodate large fillet radius on performance crankshafts

K&N Performance Gold Oil Filters

Get oil filtration that's as good as gold with K&N Performance Gold oil filters. Keep your engine free from contaminants as small as 10 microns. They use a resin-impregnated filter media to provide maximum filtering and an inner core to lend extra structural support to the filter, preventing filter collapse. Plus, many of these K&N oil filters have an anti-drainback valve (where applicable) that eliminates dry starts and prevents oil from draining back into the crankcase during engine shutdown. And they're protected by a heavy-duty outer shell that guards against rock and stone damage and provides over 550 psi hydrostatic burst strength. So, if you want golden-level oil protection, then you want K&N oil filters.

King HP-Series Rod Bearings

King HP-Series rod bearings were developed mainly for drag race applications needing a material harder than the Babbitt top layer. These applications demanded a structure that could withstand high loads for short durations and still offer higher embeddability and compatibility. In response, King developed the HP-Series, featuring the Alecular metal structure. The HP-Series is also suited for many performance applications with nodular cast iron crankshafts, such as street, strip, and some levels of Circle Track racing. Order the set recommended for your vehicle. HP-Series bearings are particularly suitable for the following cases: * When a tri-metal bearing's Babbitt overlay extrudes over the sides, migrates to one end, or is physically removed by the crankshaft * When the intermediate layer of a tri-metal bearing is exposed, damaging the crank journal and requiring expensive grinding or replacement * When contaminants enter the oil stream, scratching and damaging the crankshaft journals

Sealed Power MA Series Main Bearings

These Sealed Power MA Series main bearings can actually polish the journals on your crankshaft. That's because there's a small percentage of silicon mixed in with the aluminum and tin that make up the bearing-surface alloy. The silicon is there for wear resistance, but its toughness actually smoothes the journals of a crank whose surface hasn't been optimized! This special surface alloy is laid over a high-strength 1010 steel backing and delivers improved seizure and corrosion resistance, as well as better control of wall variance. It also helps to minimize debris embedding, which can score the crank's surface.
