BJYXSHOP Rear Air Spring Kit For Lincoln Town Car
The BJYXSHOP kit provides two rear air spring bags designed for 1992-2011 Mercury Grand Marquis, 1990-2011 Lincoln Town Car, and 1993-2008 Ford Crown Victoria. The replacements match OE numbers to simplify ordering and installation (3U2Z5580AA, 3U2Z5580BA, 3U2Z5580PA, 6W1Z5560AA, FOVY5560A). Built with imported high-density rubber, these bags offer improved load support and durability over standard springs. The package supports restoring ride height and leveling after wear, helping maintain luxury-feel handling and comfort. Proper fitment relies on accurate OE-number matching and correct mounting points.
Installation is typically straightforward for technicians familiar with air-suspension systems. Users report noticeable improvements in ride quality and reduced sag under load. The bags are designed to withstand road stress and temperature variations, contributing to longer service life when maintained and inspected periodically for leaks or wear. For best results, inspect surrounding lines and connections during replacement and reseal mounting hardware as needed.
AKWH 949-200 Air Suspension Compressor Pump
The 949-200 compressor pump from AKWH is a direct replacement part for air suspension systems associated with 1990-2011 Lincoln Town Car, 1990-2011 Mercury Grand Marquis, and 1993-2011 Ford Crown Victoria. OEM-related part numbers include 949-200, 3W1Z5319BA, 6W1Z5319AA, and others. This unit helps restore proper air pressure when the system leaks or the original pump fails. A typical symptom is the pump running continuously due to a leak or valve failure. It is essential to check for air leaks in lines and seals before and after installation to maximize pump life and system efficiency.
When selecting a replacement, verify compatibility with the vehicle’s year and engine configuration, and confirm that the dryer and related seals are included or compatible. Regular maintenance, including inspection for leaks and timely replacement of worn components, will extend the life of the compressor and protect the entire air-suspension circuit from overworking the pump.
Vixen Onboard Air Suspension Kit With Tank
This premium onboard air suspension kit from Vixen is designed for trucks and cars needing higher air demand. It features a 5-gallon tank with nine ports, two 200 PSI compressors, four 2600-style air bags, high-flow valves, water traps, and a dual gauge panel with a four-way switch control. Installation hardware is included. The dual compressors reduce refill time, enabling rapid height adjustments for load leveling, towing, or dynamic ride height changes. The system supports a quick rise in height with a robust tank that maintains air reserve for consistent suspension performance.
With universal bag compatibility and high-flow valves, this kit improves response time and ride stability under varying loads. The onboard design helps minimize degree lag between height changes and the ride height, providing improved handling during cornering and braking. For users seeking a ready-to-install, higher-capacity solution, the Vixen kit offers durability and performance with comprehensive control options.
maXpeedingrods Rear Air Suspension Bags
The maXpeedingrods bags are designed for Ford Crown Victoria (1992-2011), Lincoln Town Car (1990-2011), and Mercury Grand Marquis (1992-2011). They reference OE numbers 3U2Z5580AA, 3U2Z5580BA, 3U2Z5580PA, 6W1Z5560AA, and FOVY5560A. Each air spring is fully inspected and tested to ensure quality components for improved ride quality and load handling. The bags are built to endure harsh road conditions and heavy payloads while maintaining comfort. This product aims to restore luxury-level ride characteristics after wear or after suspension sag occurs.
Manufacturers emphasize quality control and precise manufacturing to ensure consistent performance. When installing, verify the correct side orientation and alignment with mounting brackets for proper seating. Regular inspection of air lines and fittings can prevent leaks, and pairing these bags with a matched compressor and controller yields the best overall results for ride height adjustment and stability.
SmartRide Rear Air Suspension Conversion Kit
The SmartRide kit provides a practical solution for converting air suspension to passive shocks and coil springs in 2003-2011 Lincoln Town Car models. This approach can reduce maintenance needs and potential failure points associated with active air systems. It replaces the expensive air components with proven, simpler suspension hardware. The kit explicitly excludes models with electronic suspension, ensuring compatibility with older or non-electronic systems. This option is often chosen when air-suspension reliability or cost is a priority and when the vehicle can benefit from a more traditional suspension feel.
Buying Guide
Choosing the right air suspension setup involves balancing vehicle compatibility, functional goals, and practical installation considerations. Below are key purchase considerations to help you compare options from bags to compressors and conversion kits.
- Vehicle compatibility and model year: Confirm the exact model year range and OE numbers to ensure a proper fit for Lincoln Town Car, Crown Victoria, and Mercury Grand Marquis variants.
- System type: Decide between bag-only replacements, full onboard air kits, or conversion kits. Bag kits restore air ride feel; onboard systems offer height control and load leveling; conversion kits are for those seeking a non-air alternative.
- Component quality: Look for high-density rubber bags, durable compressors, and reliable valves. OEM reference numbers (OE numbers) are helpful for accurate replacements and future maintenance.
- Tank capacity and air flow: A larger tank and higher PSI capability enable faster height changes and better load handling, especially when towing or carrying heavy payloads.
- Installation complexity: Some kits are plug-and-play with minimal modifications, while others require professional mounting brackets, lines, and electrical wiring.
- Maintenance and durability: Inspect hoses, fittings, and the dryer; be mindful of potential leaks that can cause the compressor to run continuously and shorten system life.
- Warranty and support: Consider brands with documented warranties and accessible customer support for parts replacement and troubleshooting.
- Price versus longevity: Higher initial costs may yield longer service life and lower long-term maintenance, but verify expected lifespans and ease of sourcing replacement parts.
When evaluating options, weigh the benefits of a robust onboard kit (tank, dual compressors, and multiple valves) against the simplicity and lower cost of a premium bag kit or a conversion approach. A well-matched package improves ride quality, handling, and load stability while reducing the likelihood of nuisance leaks or electrical issues. For most owners, choosing a branded kit that prioritizes OE compatibility, solid rubber components, and reputable installation support offers the best balance of performance and reliability over time.
