It's no secret that no matter what you're driving, whether it's a slammed or raised truck or a road-scorching Vette, suspension is the key to handling. A truck that has less horsepower but a tight and responsive suspension will be more fun to drive than one with gobs of power and a suspension that's loose and unmanageable.
Of course, the best situation is to have more power than you need and a suspension that can take full advantage of it. That’s what we’re shooting for with our 1968 GMC. To make this a reality, we contacted Dave Clark at Early Classic Enterprises for a set of the company’s dropped spindles and coils. Early Classic manufactures a wide variety of suspension lowering components for 1963-1987 GM trucks as well as disc brake conversion kits. And since we were going to need something to slow down this beast, Early Classic got us a disc brake conversion with cross-drilled rotors.
We ordered the rotors with a 5-on-5 bolt pattern, but Early Classic also has the early GM six-lug bolt pattern for truck owners who don't want to swap their wheels and tires or change the rear-end bolt pattern.
Even the best suspension products won't work well if the bushings and other components are worn-out, so we contacted Performance Suspension Technology for one of its complete suspension rebuild kits. Once we had everything we needed, we headed up to Early Classic Enterprises in Fresno, California, and followed Dave Clark as he got our chassis back on its wheels.
