PWR 42-1917 Rack and Pinion Assembly

PWR 42-1917 Rack and Pinion Assembly

The PWR 42-1917 is a hydraulic rack and pinion assembly for select Chevrolet Colorado, GMC Canyon, and Isuzu i-280/i-350 applications. Built as a direct-fit replacement, it is engineered for easier installation and tested for leaks, pressure, noise, and function before release.

Key Features

• Hydraulic rack and pinion assembly
• Direct-fit design for straightforward replacement
• USA engineering approved
• Gasket or seal included
• Inner tie rods included
• Female inlet and outlet line fittings, 12 mm
• 3.2 turns lock-to-lock
• 16.8 mm steering input shaft diameter
• End-to-end length: 1225

Detailed Description

This PWR steering rack is built for vehicles that use hydraulic power steering and the listed OE-style mounting and line connection dimensions. The 42-1917 matches applications for 2004-2006 Chevrolet Colorado and GMC Canyon, including off-road chassis package Z71 versions, plus 2006 Isuzu i-280 and i-350 models with the specified tie rod diameter and VIN breakpoints. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. If you are replacing a worn steering rack on a Chevrolet Colorado, GMC Canyon, or Isuzu i-350, this assembly provides the core hydraulic steering components needed for a direct replacement.

What It Helps Address

• Steering play or looseness at the wheel
• Hydraulic fluid leakage from the rack assembly
• Rough, noisy, or inconsistent steering response
• Internal wear in the steering gear assembly
• Loss of steering precision in daily driving or off-road use

Installation Notes and Tips

Verify VIN breakpoints, chassis package, and tie rod diameter before ordering. This assembly uses two mounting holes, female 12 mm inlet and outlet fittings, and does not include mounting hardware, mounting brackets, or outer tie rods. Confirm steering shaft diameter and line connections against the original unit before installation. Professional alignment is recommended after replacement.

Quality Assurance

PWR states that its pumps, racks, and gears are fully tested for leaks, pressure, noise, and function. The manufacturer also identifies this unit as USA engineering approved.
