Upgrade the steering on your classic 1955-57 Chevy with UniSteer's Power Rack and Pinion Kit, designed specifically for the iconic Tri-Five models. This kit features a modified traditional GM rack and pinion, perfectly engineered to match the stock suspension of your Chevy. The rack is machined to be narrower, ensuring a seamless fit with the original suspension geometry. It mounts directly to the frame, using a one-piece bracket that bolts into the same location as the old steering box and idler arm, simplifying the installation process.
This power rack and pinion kit is optimized for small block engines with headers, and it has been successfully paired with Sanderson and FlowTech headers. Note that a switch to a hydraulic clutch is necessary, as these headers are not compatible with mechanical clutches. For big block engines, LS1, LSX, and ZZ4 motors, this kit can be used with some modifications, including the use of three u-joints, a support bearing, and potential header adjustments. The kit is versatile enough to work with Mike McGuagthy's drop spindles, though slight modifications to the inner ends may be required.
The rack offers less travel than the original pitman arm, so the included steering arms are essential for maintaining a comparable turning radius. UniSteer also offers custom-built pump kits designed to work perfectly with this rack and pinion, available separately. For those with small block motors, UniSteer provides shaft kits that include two joints, DD shafting, and a coupler for aftermarket columns or a bearing to reuse the factory column.
This kit is designed for floor shift vehicles. If you're using a column shift, upgrading to an Ididit column is recommended. UniSteer also offers a range of compatible products, including Ididit Columns, and Sanderson and Flow Tech Headers.
