Why Choose Westar for Air Spring to Coil Spring Conversion?
For drivers dealing with a failing or aging factory air suspension, Westar offers a straightforward, proven path forward: swap out the complex, failure-prone air system for a reliable, traditional coil spring setup. Westar's Air Spring to Coil Spring Conversion Kits are engineered for owners who want to eliminate the recurring costs and headaches of air suspension repair without sacrificing ride quality or vehicle integrity.
What's Included & How It Works
Air suspension systems — common on luxury sedans and larger vehicles from Ford, Lincoln, and Mercury — rely on pressurized air bladders, compressors, solenoids, and electronic controls to deliver a smooth ride. When these components fail, repair costs can be steep. Westar's conversion kits sidestep that problem entirely by replacing the active air suspension with a passive coil spring system.
Each kit is sold as a complete package. Westar includes all of the necessary fittings and adapters to install the system correctly and to restore the vehicle to its original ride height — meaning you're not hunting for additional hardware after the fact. Kits are available for both front and rear axle positions, covering vehicles such as the Lincoln Continental, and select Ford and Mercury passenger cars spanning model years from the early 1990s through the early 2010s.
Known part numbers in this lineup include the CK-7800, CK-7810, CK-7815, CK-7819, CK-7831, and CK-7841WS — a focused range of five SKUs targeted at the most common air-suspension platforms that benefit from conversion.
Quality Standards & Manufacturing
Westar's conversion kits aren't simply aftermarket replacements — they're built to meet or exceed OEM specifications. The company's factories manufacture to strict ISO, QS, and TS standards, and every product supplied is new, not remanufactured. That commitment to fresh-build quality matters in a category where component fatigue is often what caused the original failure in the first place.
As a cost-saving alternative to outright air suspension replacement, these kits deliver a significant value proposition. Replacing an entire active air suspension system — compressors, air springs, solenoids, and electronics — can run into hundreds or even thousands of dollars. A coil spring conversion simplifies the system, reduces future maintenance exposure, and restores dependable, predictable handling characteristics.
Who These Kits Are For
- Owners of older luxury sedans whose factory air suspension has failed or is failing
- DIY installers looking for a complete, hardware-included solution
- Shop technicians wanting an OEM-spec alternative that doesn't require sourcing separate components
- Budget-conscious drivers who prefer the long-term reliability of a passive coil spring setup
