Working our way through updating Classic Performance Products' '62 Impala, the next step after a frontend rebuild and the addition of new front and rear disc brakes was an upgrade of the steering system and the addition of front and rear sway bars.
CPP is offering a new 600 series steering box designed around a modern Saginaw steering box. CPP's power recirculating ball gears feature low friction and quick response. This is the same style of steering currently used in NASCAR applications and all CPP components are new (not rebuilt), and 100-percent tested in the factory.
Specifications of the '58-64 Chevrolet steering boxes available from CPP include a 14:1 steering ratio, a three-quarter 30 spline input shaft (same as 605) and a 36-4 tapered spline sector shaft (same as original '58-64 boxes).
After the steering upgrade, our final suspension improvement was the installation of front and rear sway bars from CPP. The easy installation can vary slightly depending on original equipment on each vehicle, but parts are supplied for all applications. Look for full details on the performance and driving impressions of CPP's upgraded '62 Impala when they get it back on the road with a new engine and trans and a reworked body covered with custom paint in a future issue of R&C.
