Details
You get a new 500 series power steering box, new centerlink, new pitman and idler arm. Power steering pump, power steering hoses, and pulleys are sold separately. 1958-'60 cars need to order the 910-32582 idler arm adapter. Steering box uses inverted flare fittings, 11/16" fine on the pressure side and 5/8" fine thread on the return side. Has a 3/4" 30-spline input shaft.
- 500 Series power steering boxes are the key components to a high performance modern style power steering system.
- Features a 14:1 ratio unit which provides superior directional control and road feedback, as well as a more stable feel to the driver.
- Recirculating ball gears for low friction and increased steering response.
- An open centered, rotary type valve provides smooth operation throughout the steering range while retaining excellent road feel.
- For the 1958-64 full-size Chevrolet, the 500 Series is a direct replacement for the manual steering box and is “bolt on” easy to install.
- Another unique feature is the mounting bosses which are integrated into the casting, eliminating the need for an external bracket and lining up perfectly to your column without shims.
- Works with both the original and aftermarket steering columns and sway bars.
- This is the very best gearbox available on the market today to convert your full-size Chevrolet to power steering.
- New high performance center link system that upgrades the stock center link, pitman arm and idler arm for the best road feel and performance
Note: Some applications require slight modification to the radiator tank to clear the steering box. The steering box provided in this kit is a 'bolt-in' application. Connecting the steering column to the steering box will require fabrication and the use of u-joints, rag joints, and steering shaft per the installers build choice.
Kit Includes:
- Pitman Arm
- Idler Arm
