Upgrading the suspension in a unibody Chevy has never been easier. Just about every suspension company worth its salt is selling complete front clips. These companies have been pushing the limits of bolt-ons for some time now, and what has come from all that testing are some pretty superior suspension systems and the subframes from which they hang. The newest trend we are seeing is front subframe assemblies that come fully complete with upgraded suspension.
As a consumer this makes the job of upgrading your stuff a weekend project instead of a long, drawn out process. Just remove all your stock stuff in one unit and replace it with the new goods. This keeps the guesswork to a minimum, as you know everything on that clip was designed to work in unison. All of the clips in this guide offer an upgrade of some sort over the stock stuff, whether it's as simple as improved steering and exhaust clearance, to a full blown upgrade over everything. We tried to provide all the information you need in the space we had, but once you are done checking it all out, make sure to contact the companies for the full details
Art Morrison Enterprises
Morrison's new GT-Sport front clip is a popular addition to any '67-'81 Camaro. It also fits '68-'74 Novas. Designed through the use of finite element analysis (FEA), the 105 lb. front clip has strength and stiffness, yet is significantly lighter than the bulky OEM unit. With reduced unsprung weight, forged aluminum C6 Corvette control arms, a shortened front view swing arm, modified caster, and adjustable coil-over shocks, Morrison's GT-Sport clip will provide the handling you want. Through use of a specially modified C6 spindle with lowered steering arm mounting, the power rack-and-pinion steering unit is mounted some 2-inches lower in the frame, which allows for a lower CG and improved handling. Pricing starts at $6,685.00.

The crew over at B'z Rods reports that after months of fine-tuning and tweaking, it has “perfected the straight axle frontend for the '62-'67 Nova.” The B'z Rods frames have been engineered with a front steer design to provide virtually no bump steer, a common problem with straight axles in the past. This clip also allows you to use almost any oil pan with plenty of clearance for those big headers. Some key features are it's made to use stock core support; super slide springs with urethane bushings; Vega steering box with polished stainless steel pitman arm; forged spindles with pre-fitted pins; 9-1/4-inch Mustang II style vented rotors with a 5x4-3/4-inch bolt circle; GM metric calipers with pads; bearings, seals, etc. The clip comes in raw steel, but powdercoating is available for an additional charge.
