Performance Crankshafts

Your crankshaft is one of the most fundamental features in your 1978 Ford F-150. It converts linear energy into rotational energy, which enables your wheels to move forward. Your pistons are also attached to the crankshaft and the flywheel. Its safe to say a crankshaft is one of the most important components in your vehicle. Like any other factory part, its not meant to work with your performance upgrades. Your crankshaft especially undergoes a lot of stress and pressure from its continuous use and engine combustion. A performance crankshaft is created to a higher standard. They are designed to handle higher loads and RPMS without cracking, failing, or twisting. When picking a performance crankshaft there are several options available including lightweight options, forged steel, and machined billet. Depending on the power your creating, and your intended use of your 1978 Ford F-150 the type of performance crankshaft recommended will vary. Sport Compact Warehouse is your premier source for performance crankshafts. If you have any questions regarding performance cranks, reach out to one of our experienced representatives and we will help you make a more informative decision.

No other engine component is subject to as much stress as the crankshaft. It’s impacted by the explosive force of combustion thousands of times every minute, yet typically will provide many thousands of miles of trouble free service in an unmodified engine. But, hop up the engine for increased horsepower and high RPM use, and that once reliable stock crankshaft can become the pin and your precious engine a very expensive hand grenade.

Many cranks are made of cast iron, which is reliable at factory power levels, but isn’t up to the demands of a performance engine. Also, the constant pounding can cause hard-to-find hairline cracks to develop, and may even cause the crank to bend. If the journals are worn, regrinding may remove the surface case hardening. Don’t run a used OE crank and risk blowing up your engine. Be safe, and make a new performance crankshaft the cornerstone of your build.

We offer performance crankshafts for all popular engines, designed and manufactured by performance crankshaft specialists, in materials and configurations for every use and horsepower output. Cast steel cranks are relatively inexpensive yet can handle some serious power. Next up the ladder in strength and price are forged followed by billet steel cranks. Forged cranks are created by pressure forming heated steel in a die, while billet cranks are CNC machined from solid steel. Regardless of the material, all performance cranks are finish machined to a greater degree of precision than standard replacement cranks.
