Have you been considering an A-arm upgrade for your C2 or C3? If so, you're not alone. Though acceptable by the standards of the era, second- and third-generation Corvette suspensions leave much to be desired when compared with more-modern offerings.

Fortunately for us performance-minded types, SpeedDirect offers a full line of chassis and suspension enhancements designed specifically for these classic Vettes. The company's Shark Bite aluminum upper A-arms, for example, greatly improve the C2/C3's suspension geometry, resulting in superior handling and cornering ability. They are even designed to work with modern, low-profile radial tires that require more positive caster than the factory arms are capable of offering. The result? Much improved steering feel and self-centering force.

According to SpeedDirect, the Shark Bite units are the only aluminum C2/C3 A-arms on the market. Amazingly, they offer an 8-pound (per pair) weight savings over the factory cast pieces and are lighter than tubular A-arms as well. The included bushings are made from Rulon, a high-performance fluoropolymer composite that won't squeak, does not require lubrication, and has a lower coefficient of friction than polyurethane.

Best of all, the Shark Bite A-arm kit is designed as a true bolt-on, with no modifications required for installation. Kits are available in both natural and polished-aluminum finishes and come with instructions, bushings, and cross-shafts. Stock (Moog) or performance ball joints are optional.

Speed Direct sells complete Shark Bite A-arm kits starting at $610. Typical labor time for installation is three to four hours, making this project ideal for a Saturday afternoon. Follow along as we conquer the job using a floor jack and stands, basic hand tools, and a ball-joint remover.
