Westar CK-7819 Rear Conversion Kit

Westar CK-7819 is an air spring to coil spring conversion kit for rear suspension applications on select Ford and Mercury SUVs and trucks. It replaces air suspension components with a coil-over-shock setup for drivers looking for a simpler rear suspension solution on the Ford Explorer, Ford Explorer Sport Trac, and Mercury Mountaineer.

Key Features

  • All product are new; Westar does not sell remanufactured units
  • Provides a more reliable alternative to the OEM air suspension
  • Offers a significant cost savings versus the OEM-style air suspension
  • Built by Westar using quality components and manufacturing standards aligned with ISO, QS, and TS requirements
  • Rear suspension conversion for coil-over-shock applications

Product Details

Westar CK-7819 is engineered for rear air suspension conversion on 1995-2001 Ford Explorer, 1997-2001 Mercury Mountaineer, and 2001-2003 Ford Explorer Sport Trac models with coil over shock rear suspension. This part number is a practical option when servicing aging air suspension systems on the Ford Explorer or Mercury Mountaineer and when a coil spring conversion is preferred over restoring the original air setup. This part cross-references Suncore 135F-30-R for the same application.

Common Problems It Can Address

  • Rear air suspension sagging after vehicle shutdown
  • Compressor cycling caused by leaking air springs or lines
  • Uneven rear ride height on Ford Explorer and Mercury Mountaineer models
  • Costly repairs tied to aging OEM air suspension components
  • Repeated air suspension warning or failure symptoms

Installation Notes and Tips

Verify rear suspension configuration before ordering. This kit is listed for rear coil-over-shock applications only, so confirm the vehicle is a 1995-2001 Ford Explorer, 1997-2001 Mercury Mountaineer, or 2001-2003 Ford Explorer Sport Trac with the matching rear setup. Compare the original suspension layout and part number CK-7819 against the vehicle before installation.

Quality Assurance

Westar manufactures air suspension components to strict industry standards, including ISO, QS, and TS standards. CK-7819 is a new part, not a remanufactured unit, and is built as a direct replacement-style conversion solution for rear suspension service.
