Summit Racing™ Coated Hypereutectic Pistons

Summit Racing™ offers coated hypereutectic pistons to furnish you with a more affordable engine build. These internal combustion engine pistons are cast using a hypereutectic aluminum alloy—and then layered with a special "break in" coating that wears to the cylinder walls. This coating provides an extra level of protection in three ways: superior thermal and wear characteristics to increase the piston strength; scuff and seizure resistance; and improved groove wear. Whatever your piston requirement, Summit Racing™ has you covered! Order the size and options needed for your application.

Summit Racing™ HDR Thickwall Chromoly Pushrods

Summit Racing™ HDR premium thick-wall pushrods are a great upgrade for your engine. Factory pushrods (and even .080 wall aftermarket versions) act like a pogo stick in a running engine. Not only is static spring pressure working against them, it's also the valvetrain inertial mass increasing with RPM. This reduces power and valvetrain life. While a .080 thin-wall pushrod may not break, it doesn't mean it's the best option. Enter the HDR's. Summit™ used FEA (Finite Element Analysis) in the initial testing. We didn't just compare them to thin-wall welded-ball factory pushrods, but with aftermarket models, as well. The results speak for themselves! * The Summit™ HDR 5/16 x .105 wall pushrods have 20 percent less stress and 25 percent less deflection than a typical 5/16 x .080 chromoly pushrod * The Summit™ HDR Pro LS 11/32 x .120 wall have 25 percent less stress and 28 percent less deflection than a typical 5/16 x .080 wall chromoly pushrod * The Summit™ HDR 3/8 x .135 pushrods commonly used in big blocks has 15 percent less stress and 20 percent less deflection than a typical 3/8 x .080 wall chromoly pushrod Summit Racing™ added other high-end features like 210 degree ball ends to cope with extreme lobe lift and clear the rocker and are available in multiple lengths. * HDR 5/16 pushrods are offered in common LS, SBC, and SBF lengths * HDR Pro LS 11/32 pushrods add .030 diameter AND .120 wall thickness over a 5/16. Although most LS engines came with 5/16 pushrods, 11/32 pushrods fit any stock or aftermarket cylinder head. The added thickness adds much needed strength to any LS cam swap or engine build. Being available in .025 in. increments allows for fine tuning of hydraulic lifter preload with the LS's non-adjustable rockers. * HDR 3/8 pushrods fit the LS7 and common BB Chevy combinations. They have .135 wall thickness for maximum strength. Pushrods are some of the best horsepower-per-dollar components in your engine, so step up to the HDR's for your build!

King TFC-Series Main Bearings

King TFC-Series engine main bearings feature a special factory applied nano-composite polymer coating—with no added thickness! The Top Fuel Line represents the culmination of the innovative and goal oriented research and production from King Engine bearings House. These bearings are available for a wide range of vehicles, especially year/make and engine applications from the 1960s and '70s. Additional details: TOP FUEL BEARINGS with K-40 POLYMER COATING: This coating composition was specially designed for engines experiencing continuous metal-to-metal contact, which is characteristic of the extreme loading and conditions found in various categories of drag racing. K-40 is used for Top Fuel, Funny Car, Pro Mod and similar applications—where bearings are required to resist metal-to-metal contact and deformation. Extreme loads cause the oil film to break down, allowing contact between the bearing and crankshaft surfaces. Maintaining low friction, even during the conditions of metal-to-metal contact, is crucial to the life of any engine bearing. King TFC bearings are designed to withstand the loading generated from 10,000 hp Top Fuel engines. TFC winning attributes: * HIGH STREGTH STEEL: able to withstand extreme loads * SPECIAL DUCTILE BRONZE LINING: will not crack under significant plastic deformation caused by high power engine (10,000 hp) * EXTRA THICK BABBIT LINING: strengthened by copper, excellent conformability * K-40 POLYMER LAYER: provides excellent anti-friction and anti-seizure properties during metal-to-metal contact

Dorman Alternator Combination Mounting Brackets

These Dorman alternator combination mounting brackets are designed to mount to the front of GM 4-cylinder engines and hold the alternator, power steering pump, air conditioning compressor, and serpentine belt idler pulley. Many times, when the above accessories are removed for replacement, the mounting bolts, after years of exposure to the elements, will corrode and rust. This rusting reaction causes the bolts to become seized and they will usually break off when you are trying to remove them, making the entire bracket useless. So, pick up one of these Dorman alternator combination mounting brackets and get your vehicle running again.

Harland Sharp Rocker Arm Shaft Spacers

Harland Sharp offers rocker arm shaft spacers for a variety of applications, including many Ford, Mercury, Chrysler, Dodge, and Plymouth engines from the 1950s, '60s, '70s, '80s, and '90s. Machined from aluminum or steel, these components are used in engine valvetrains to adjust the alignment of the rocker arm roller tip on the valve stem. They're placed on the rocker arm shaft to shim the rocker arm assembly, ensuring the roller rolls in the center of the valve tip and improving valve alignment. This alignment is critical for engine efficiency and prevents premature wear, especially at higher RPMs. Additional details: * Shims are used to push the rocker arm assembly sideways on the shaft * Centering the roller prevents it from walking off the end of the valve, which can cause parts to break * The shims are primarily used in engines with shaft-mounted rocker arms, especially for high performance applications where engine stress is higher * Various thicknesses and inner diameters are available to fit different engine specifications
