RideTech’s revolutionary new Bolt-On 4-Link for 1970-1981 Camaros and Firebirds is unlike anything else on the market. We’ve been showing off the system’s performance at high performance driving events from coast to coast. Now it’s time to show you how easy it is to install the new design on your second-gen. We chose Scott Brown’s sharp 1981 Z28. With enough horsepower to run a low 10 second ET, Scott’s Z will really benefit from the strength and geometry of the new design.
A rear subframe layout called the “Unicradle” employs supplemental frame rails and a forward bulkhead brace to locate the eight link pivot points. Second-gen F-body rear frame rails are known for their structural weakness and manufacturing variations. With more available power and traction, RideTech realized the need for a better design that does not rely on the stock weak frame rails.
RideTech’s “Unicradle” design features three key elements that are unlike any other 4-Link design on the market. Unique rear subframe rails attach to the four leaf spring perch mounts. From there, the shock crossmember attaches to the subframe rails. The second key element of the Unicradle design is the tubular bulkhead brace which bolts to the car’s bulkhead (rear firewall) and transmission tunnel. The brace accepts the forward ends of the upper links. The last design element is the use of R-Joint rod ends and spherical bearings at all link points. R-Joints offer high articulation, long wear resistance and quiet operation.
Here we are installing the new Unicradle Bolt-On 4-Link on Scott Brown’s beautiful 1981 Z28. The car has been in Scott’s family since new. It now features a 700HP LSA and massive 335mm wide rear tires. With so much horsepower and available traction, our math suggests that the new Unicradle Bolt-On 4-Link might be able to help Scott’s Z run sub-10 second elapsed times in the 1/4 mile — on air suspension. We intend to find out.
