long-icon-questionWhy Choose Strutmasters?

Why choose the Conversion Kit over replacing the air suspension system on your 1986-1991 Oldsmobile Delta 88?

The original air suspension system on the Oldsmobile Delta 88 is made up of assorted parts that must always work together. This reliance is inefficient and costly. Strutmasters' air to non-air suspension conversion kit gets rid of the dependence for good. Made in America, the kit comes complete with two custom-rated Eibach coil springs and two hydraulic fluid gas-charged struts for the rear. This affordable direct replacement solution eliminates the hassles of failing onboard compressors and level sensors permanently. No modifications are needed prior to installation. Customers appreciate the detailed instructions and online installation videos that help them get the kit installed in as little as one hour per wheel. If further assistance is needed, ASE-certified experts offer technical support over the phone. The quality parts in the kit are more reliable than the originals. But perhaps most appealing to Delta 88 owners is the low price; the kit costs considerably less than dealership direct replacement and individual part replacement.

long-icon-xIs Your Suspension Failing?

How do I know if my 1986-1991 Oldsmobile Delta 88 Air Suspension is failing?

Look for the classic signs that indicate the 1986-1991 Oldsmobile Delta 88's air suspension system is leaking or going bad. Early detection of a failed suspension is the key to avoiding total failure. A suddenly uneven height difference between different sides of the Delta 88 is a red flag. Typically the rear end of the vehicle will sag, giving the illusion the Delta 88 is “squatting down” in the rear. Some drivers notice a shifting lean from one side to the other. Height imbalances will wear out the air compressor if they are not fixed promptly. If the air compressor runs too often or stops working, suspension failure will progress. If a suspension warning light illuminates on the instrument cluster, the Delta 88 owner should seek a repair immediately.

long-icon-gearVehicle Components

What kind of suspension does my 1986-1991 Oldsmobile Delta 88 have?

The 1986-1991 Oldsmobile Delta 88 is built with the following rear suspension components:

1986-1991 Oldsmobile Delta 88 Air Struts (x2) - struts that contain an air bladder whose dampening capabilities is controlled by the suspension control module; they serve two purposes. These connect the wheel of a vehicle to the driving surface in order to reduce the effects of vertical travel on a rough surface which controls the bounciness, and therefore comfort, of a vehicle. They also help maintain the vehicles correct ride height, especially whenever the amount of load put onto the vehicle changes.

1986-1991 Oldsmobile Delta 88 Coil Springs (x2) - what we love! Coil springs hold the vehicle up but be careful, they are rated for and designed to work with the rest of the suspension system, so when you change air shocks to passive shocks, then you will need a different rated coil spring that works well with the new type of shocks.

1986-1991 Oldsmobile Delta 88 Height Sensors (x2) - a linkage located near each wheel of a vehicle with any electronic suspension that, either mechanically or electronically, constantly measures the height of the vehicle, and reports this information back to the control module so that the computer can identify if changes in height need to be adjusted accordingly. The ride height sensor is a moving part, and like all moving parts, they will eventually wear out.

1986-1991 Oldsmobile Delta 88 Air Lines - tubes that run from a compressor to the air which carry pressurized air to the air struts in order to adjust the height of the vehicle, respectively.

1986-1991 Oldsmobile Delta 88 Compressor Assembly - creates/sends pressurized to active suspension components. When the air suspension starts leaking, the compressor/pump starts working harder to try to keep the system inflated. By the time air suspension leaks down completely, sitting the vehicle on its tires, the compressor will either have failed or be well on its way to full failure. Buying replacement struts and taking the time to install them only to find out the compressor still needs to be replaced can be very frustrating, time-consuming, and expensive.

1986-1991 Oldsmobile Delta 88 Dryer - prevents moisture build-up inside of air suspension parts.

1986-1991 Oldsmobile Delta 88 Suspension Control Module - a computer which is responsible for the operations of the air suspension system and maintaining the vehicle’s correct ride height.

1986-1991 Oldsmobile Delta 88 O-rings - Although they are the least expensive parts of the air suspension, they are responsible for maintaining the seal where all of the air lines connect. Be sure to replace the O-rings when repairing any air suspension system.
