Classic 1955–57 Chevy Full Size cars have timeless style, but many still drive with original-style steering that can feel heavy, loose, or outdated by modern standards. Whether you are building a restored cruiser, a weekend driver, or a more performance-minded Tri-Five, upgrading the steering system is one of the best ways to improve confidence behind the wheel.
Why Upgrade the Steering on a 1955–57 Chevy? The factory steering setup on a Tri-Five Chevy was built for a different era of driving. Around town, in parking lots, and during low-speed maneuvers, manual steering can require extra effort. Even older power steering systems may feel vague, worn, or less responsive than today’s drivers expect.
CPP’s 500 Series Power Steering Conversion Kit helps address those issues by replacing the original-style steering setup with a more modern power steering box and matched components. The result is improved steering response, easier low-speed handling, and a more comfortable driving experience. The CPP5557PSK-S kit is built for 1955–57 Chevy Full Size models with side engine perches. It includes CPP’s 500 Series power steering box along with the key components needed to complete the conversion on small block Chevy applications. This kit is a smart option for builders who want a complete steering upgrade package instead of piecing together individual parts.
The CPP5557PSK-S kit includes:
- CPP 500 Series power steering conversion box
- Power steering hoses
- Small block Chevy power steering pump
- Power steering pump bracket
- New steering gearbox
- 14:1 steering ratio
- 3.5 turns lock-to-lock
- Black finish power steering pump
- Clear finish pump bracket
- The kit is designed for small block Chevy applications with side engine perches. The pulley and rag joint are sold separately, so those items should be considered when planning the full installation.
Built for Better Road Feel: One of the biggest advantages of the CPP 500 Series steering box is the improved steering feel. A quicker 14:1 ratio gives the car a more responsive feel compared to older, slower factory-style systems. With 3.5 turns lock-to-lock, the steering feels more connected without making the car uncomfortable for street use. For classic Chevy owners, this means less steering effort, better control, and a more enjoyable drive whether you are cruising through town, parking at a show, or heading out on the highway.
Designed for a Cleaner Conversion: CPP designed this kit to help simplify the power steering conversion process. The 500 Series box is made to bolt to the frame like the original equipment, helping reduce the need for major fabrication. By including the steering box, hoses, pump, and bracket in one package, CPP gives builders a more complete starting point for the upgrade. This is especially helpful for projects where the original steering parts are worn, missing, or no longer matched to the engine and suspension setup.
Important Fitment Notes: This kit is intended for 1955–57 Chevy Full Size vehicles with side engine perches and a small block Chevy engine setup. CPP also offers other versions for different configurations, including front engine mount applications. Before ordering, confirm your engine mount style, steering column setup, pulley arrangement, and rag joint requirements. The pulley and rag joint are not included with this kit, so those parts will need to be selected separately for your specific build.
Who Is This Kit For? The CPP5557PSK-S kit is a great upgrade for:
- 1955 Chevy Full Size builds
- 1956 Chevy Full Size builds
- 1957 Chevy Full Size builds
- Tri-Five cars with side engine perches
- Small block Chevy-powered street cars
- Restorations that need better drivability
- Weekend cruisers and highway-driven classics
- Builds replacing worn or outdated steering components
- If you want your classic Chevy to feel easier to drive without losing its vintage character, this kit is a strong upgrade.
A Better Driving Experience for Your Tri-Five: Steering is one of the most noticeable parts of any classic car build. When the steering feels loose, heavy, or unpredictable, the whole car feels less enjoyable. CPP’s 500 Series Power Steering Conversion Kit helps transform the driving experience by giving your 1955–57 Chevy a smoother, more responsive, and more confident feel. For builders looking to modernize their Tri-Five without overcomplicating the project, the CPP5557PSK-S kit brings together the right core components in one package.
