DOUQANG Upgrade Conversion Kit Power Steering Gear Box
The DOUQANG kit targets mid-century Chevrolets using the 500/605 power steering boxes. It includes a 500-series steering box, a black power steering pump, a mounting bracket, hoses, and bolts. Best for owners of 1958–1964 Bel Air, Biscayne, and Impala models seeking a direct bolt-on upgrade from manual steering. The 14:1 ratio provides a predictable, traditional steering feel. A potential limitation is compatibility with non-500/605 boxes, so verify fitment before purchase. Choose this if you want a complete, factory-mimicking upgrade with minimal fabrication.
Fizzvex Power Steering Conversion Kit for Chevy Bel Air 150 210 500
The Fizzvex kit is tailored for Chevy Bel Air models from 1955–1957, covering the Bel Air and One-Fifty series. It lists OE part references to guide correct installation and part compatibility. Best for restorers who want a period-correct setup with modernized performance. This kit can be a better choice when restoring a 1955–1957 Chevy and you want to align with factory specifications. A caveat is that availability and exact component matching can vary by supplier, so confirm the specific SGB/CV references match your chassis.
Borgeson 999062 Power Steering Conversion Kit
Borgeson 999062 targets 1949–1951 Ford full-size cars. This conversion kit focuses on providing a reliable steering upgrade for early Ford models, leveraging Borgeson’s reputation for power steering hardware. Best for enthusiasts restoring early Ford lines who need a straightforward upgrade path. The kit’s limitation is its specificity to Ford full-size cars of that era, so it is not a universal solution for all Fords or other brands. Choose this if you own a pre-1952 Ford full-size and want a proven conversion pathway.
Power Steering Gear Box Conversion Kit Replacement for Chevy Bel
NEWZQ’s kit is pitched as an OE replacement for Chevy’s 500 Series gear boxes, aligning with Bel Air models from 1955–1957. It’s best for owners who prefer a direct gear-box replacement approach rather than a full retrofittable system. This kit is described as a replacement option that can simplify the upgrade path, though compatibility with non-500 series pumps or brackets should be verified. Choose this if you’re aiming for a straightforward, factory-like gearbox replacement.
1957 Compatible with Chevy Power Steering Conversion Kit
This Speedway Motors kit is designed for 1957 Chevy applications and includes a 500-series power steering box, along with a centerlink, Pitman arm, and idler arm. It is best for owners upgrading a 1957 Chevy with a tilt- column and a desire for a complete steering system overhaul. The kit provides an integrated solution that reduces the need to source separate components. A limitation is that it targets a specific year and may require additional parts for non-1957 configurations. Choose this if you want a cohesive, period-appropriate upgrade kit with essential steering components.
