Your 1963-1982 Corvette front crossmember is subjected to large rocks, unimaginable road debris and damage from repair work (poorly positioned floor jacks). As a result, many, if not all, the frames under C2 and C3 Corvettes have caved-in front crossmembers. The repair tool (Corvette Central part number 182100) will aid in straightening your crossmember if the majority of damage is within the perimeter of the inner forcing plate coverage area. (more…)
The third-generation Corvette is perhaps the most-overlooked model of all ‘Vette styles. Despite being saddled with carrying the Corvette nameplate through the smog years, some of the earlier models were factory-equipped with decent small- and big-block engine options. The focus of our article today is a 1969 Corvette stuffed with a Tri-Power 427 cubic-inch big-block engine that produced 435 horsepower upon delivery, and we’re going to release the sound and fury in the chambers by installing a set of Doug’s Headers sidemount headers and exhaust pipes – which offer good looks and easy installation to go along with the legendary Doug’s Headers performance and sound.

Before an alignment is done, it is important to make sure all suspension components are in good shape. For example, loose wheel bearings on the front or rear will affect alignment and worn components front and rear will alter the alignment over time. Tire wear will indicate how the suspension and tires are handling the adjustments. (more…)
Power steering is a mechanical wonder that many of us often take for granted. For some, it is hard to even remember a time without power steering. Today’s systems are cost effective to manufacture and are very reliable with just basic maintenance. It is likely that these systems will remain in place for several more years despite the pressure to continually increase fuel economy.
The power steering system consists of a reservoir, pump, relief valve, control valve, power cylinder, and high/low pressure hoses. The system is effective because of the pressure differential that is created by the power steering pump. A quick explanation of how power steering works is in order. The reservoir supplies the fluid to the pump, which is driven by the engine via belt. The fluid is pressurized and sent to the control valve and the relief valve. When the steering shaft is turned, the control valve sends fluid to the power cylinder and the power cylinder uses a piston to aid in reducing steering effort. (more…)
You know it will eventually happen: your C3 Corvette’s door hinges wear out and the resulting alignment issues cause a multitude of problems. Sagging, broken seals, road noise, and water leaks to name a few.
Have you ever wondered how many times you have opened and closed the doors on your Corvette, especially the driver’s side door? It has to be thousands of times and the number only increases as a car ages. Owners used to lube their door hinges at every oil change. As oil change intervals increase and busy schedules ensue, these small but important maintenance tasks are often ignored and will eventually lead to door misalignment problems. (more…)
