Tired of steering your classic Chevy all over the road? That steering box was great almost 60 years ago but there is new solution! Try our bolt in rack & pinion – travel light years ahead in steering technology – your Tri-5 will turn like a dream.
We used a modified traditional style GM rack and pinion for the Tri-5s. The rack is bolted to a one-piece bracket which mounts exactly where the old steering box and idler arm were mounted to the frame. The rack is machined so it is narrower, matching the stock suspension of these cars. This kit is designed for use on cars with small block motors with headers; Sanderson and Flow Tech headers have been successfully used. Other headers may work as well but may require modification or a shaft kit with three U-joints. Unfortunately, the kit does not work on small blocks with stock manifolds. Installs on Big Block Motors have been done but are more difficult as it will require 3 U-joints, a support bearing and probably modification to the headers. There is a specific kit for Big Block motors, as well as LS1, LSX and ZZ4 motors, in which the lines have been modified for more clearance for Oil Pans. This rack kit will also work with Mike McGuagthy’s drop spindles with slight modification to the inner ends.
The Rack & Pinion kit includes outer tie rod ends, all hardware and new bolt on steering arms. The rack does have less travel than the old pitman arm so the arms are necessary to maintain comparable turning radius. Pump kits built how you want and matched to run with the rack & pinion are available but sold separately due to variations. Check out our pump section for Brackets, Pulleys, Reservoir and Pump options. We also have shaft kits for Small block motor cars which consist of two joints, DD shafting and a coupler for aftermarket columns or a bearing to reuse the Factory Column.
