long-icon-questionWhy Choose Strutmasters?

Why choose the Conversion Kit over replacing the air suspension system on your 1987-1990 Pontiac Bonneville?

The original air suspension system on the 1987-1990 Pontiac Bonneville is made up of assorted components that must always function together. If one part stops working, the entire system is defunct. Strutmasters' air to non-air suspension conversion kit, made in the USA, eliminates this reliance forever. The kit comes complete with two pre-assembled coilover struts that are installed in as little as one hour per wheel with two bolts each. Customers appreciate the helpful guidance of the detailed instructions and online installation videos. Strutmasters' ASE certified experts are available to offer tech support over the phone when further help is needed. The quality parts are guaranteed by Strutmasters' Lifetime Limited Warranty. But perhaps the most appealing aspect of the kit is its low price. The kit costs a fraction of the alternative solutions- dealership direct replacement and individual part replacement.

long-icon-xIs Your Suspension Failing?

How do I know if my 1987-1990 Pontiac Bonneville Air Suspension is failing?

Early diagnosis of a failed or leaking air suspension system in the 1987-1990 Pontiac Bonneville is critical to avoiding total failure. Look for these classic symptoms that indicate the air suspension is going bad- before it's too late. An inability of the Bonneville to maintain its proper ride height is one major sign. Any height variance between different sides of the Bonneville is also indicative of a bad suspension. This may look like one sagging end, one inflated end, a shifting lean, or a “squatting” appearance. These height imbalances should be fixed immediately, otherwise, the air compressor will wear out from extra strain. Once the air compressor has stopped working, a suspension warning light typically illuminates on the dash.

long-icon-gearVehicle Components

What kind of suspension does my 1987-1990 Pontiac Bonneville have?

The 1987-1990 Pontiac Bonneville is built with the following front suspension components:

1987-1990 Pontiac Bonneville Electronic Struts (x2)- a type of shock absorber; has metal tubing filled with gas-charged hydraulic fluid that is connected to the wheel of a vehicle in order to reduce the effects of vertical travel on a rough surface which controls the bounciness, and therefore comfort, of a vehicle. The Buick Electra’s struts use an electronic signal to stiffen or soften the dampening of the strut.

1987-1990 Pontiac Bonneville 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.

1987-1990 Pontiac Bonneville Suspension Control Module- a computer which is responsible for the operations of the electronic suspension system and maintaining the vehicle’s correct ride height.
