The chain of command between a crankshaft, camshaft, and engine valves is central to your vehicle's basic movement—which is why it's so important to protect the timing belt. Fel-Pro timing cover gaskets provide a tight seal to keep contaminants out of the gear shaft area. They're offered in hundreds of single or multi-piece sets for OE-style fitment on a wide variety of cars, trucks, vans, and SUVs; gaskets for industrial use are also available. Ideal for stock replacement (not intended for racing applications), Fel-Pro gaskets are made from materials such as fiber, cork, and rubber. Choose the kit which corresponds to your year/make and engine application.

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.

Cometic MLS head gaskets are constructed from multiple layers of stainless steel for strength and contain load-controlled embossments that conform load distribution across the sealing area. This creates an exceptional seal by requiring less clamp load—resulting in less bore distortion. The stainless steel outer layers utilize FKM (Viton®) rubber coating, a high-temperature and chemical-resistant polymer. A topcoat of PTFE aids in resistance to fret and increased cold sealing. MLS head gaskets are available for most aftermarket cylinder heads; as with all of Cometic's MLS head gaskets, no sealants or re-torque is required.

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.

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

Melling timing chain sets are designed for use with either performance or stock cams. They have a solid-bushing chain for a true bearing surface that rolls with the sprockets, eliminating chain stretch. The crank gears are machined from stress-proof steel. Most Melling timing chain sets have three keyways to ensure accurate timing for early or late model vehicles, and to allow you to set the cam timing at 4 degrees advanced, 4 degrees retarded, or stock. However, 50-state (stock replacement) sets have single keyways. The chains are available in several styles, such as single or double roller, single non-roller, and link belt. Melling timing chain sets are not for use above 6,500 rpm. Order the model designed for your vehicle application.

Oxygen sensors, also known as Lambda sensors or O2 sensors, are among the most sensitive and critical components on your car's engine. They monitor the air/fuel mixture under idle, moderate acceleration, and cruise conditions. Oxygen sensors have a smaller range of limits in detecting and adjusting the difference from an optimum air/fuel ratio than the newer wide range air/fuel sensors (A/F sensors). Today's engines may use as many as four oxygen sensors to monitor exhaust gas oxygen content and catalytic converter efficiency. In order to perform these functions properly, Denso oxygen sensors adhere to strict OE standards within incredibly close tolerances. A malfunctioning or incorrectly calibrated oxygen sensor can hurt drivability and illuminate the check engine light, resulting in costly and time-consuming repairs. Denso First Time Fit oxygen sensors are designed to meet those tolerances and more. Key features and benefits of Denso Oxygen Sensors include: * Robotic laser welds * Porous PTFE filters block efficiency-robbing contaminants * Double-protection covers maintain proper temperature for quicker response times and protect ceramic elements from silicone and lead fouling * Rugged, watertight stainless steel housings resist corrosion and contamination * Aluminum oxide trap layers keep silicone and lead out, preventing damage to the platinum electrode * Refined zirconia elements improves sensor response * Superior design maximizes engine performance while reducing fuel consumption and harmful emissions * First Time Fit design delivers the right part the first time
