Arnott Air Suspension Products has introduced a new rear air shock AS-2950 for the 2006-2011 Cadillac DTS and Buick Lucerne with Sport Suspension (F55 MagneRide). Arnott Air Shock AS-2950 converts the vehicle's electronic shocks to a much more dependable passive air shock system and keeps the rear air leveling system completely operational. Arnott has designed this shock to plug directly to the vehicle's computer system without any alterations. AS-2950 replaces OE Part Numbers: 19302768 15211375 19302769 15211376 Arnott's exclusive plug-in design allows for easy installation. This new aftermarket Cadillac or Buick air shock, which retails for $199, is so durable it is backed by Arnott's Limited Lifetime Warranty. Arnott-designed new shocks are an excellent alternative for aging air suspension systems because they provide the luxury, comfort and auto leveling of air springs but replace the older auto damping shock with a brand new shock custom-valved to provide a great ride at a more affordable price. Arnott Recommends Replacing These Shocks In Pairs.
