If you're running a single fan on your Corvette's stock radiator, then it's time to upgrade to DeWitt's aluminum electric dual Spal fan kits. These cooling systems are designed to move a massive amount of air when needed—the fan speed increases as temperatures rise. At the programmed upper threshold temperature, the primary fan speed reaches 100 percent and the secondary fan kicks in to help. As the temperature drops down, the secondary fan cycles off, and the primary slows, giving you a constant cooling temperature. You get uncompromised cooling under all driving conditions.

TCI StreetFighter transmissions are durable enough to withstand the rigors of even the toughest street machines. Equipped with a manual/automatic valve body, most units allow you to manually shift the vehicle into each gear change or, by placing it in the drive position, remain fully automatic. In either mode, you get a race track shift that bangs through the gears and shaves time off of your ETs. When you use the manual gear selection feature, the StreetFighters upshift and downshift right when you move the lever, with no lag or governor override. When you select the normal drive position, they retain positive automatic shifts for the ease of driving you look for in an automatic transmission.

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
