Why Choose Strutmasters Instead Of Those Other Guys

In short, Strutmasters' air to non-air suspension conversion kit saves Seville owners time, frustration, and money when the air suspension system goes bad. The kit eliminates the inefficient dependency on various parts always functioning in unison. The kit, made in America, comes complete with two pre-assembled front struts with Eibach springs and mounts, one electronic bypass to remove the service ride control message, and all necessary hardware. The kit is installed in as little as one hour per wheel, thanks to detailed instructions and online installation videos. If further help is needed, ASE certified experts offer technical support over the phone. The quality parts are guaranteed by Strutmasters' Lifetime Limited Warranty. But what seals the deal for most Seville owners is the low price. The kit costs a fraction of the prices of dealership direct replacement and individual part replacement.

How Do I know If My Seville Air Suspension is failing?

If the 1998-2004 Cadillac Seville is unable to reach and maintain its proper ride height then it may be suffering from a failed or leaking air suspension system. Early detection of a bad suspension is the key to avoiding total failure, so look for these classic symptoms. A sudden height variance between different sides of the Seville is common. Typically, one end will sag while the other end is inflated. This may give the illusion the Seville is “squatting down” in the rear. There may be a shifting lean from side to side. These imbalances, if not fixed promptly, will wear out the air compressor. Once the air compressor has stopped working, a suspension warning light will illuminate on the dash.

Suspension Components List

The 1998-2004 Cadillac Seville is built with the following front suspension components:

1998-2004 Cadillac Seville 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 Cadillac Seville’s struts, while having coil-springs, use an electronic signal to stiffen or soften the dampening of the strut.

1998-2004 Cadillac Seville 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.

1998-2004 Cadillac Seville Suspension Control Module- a computer which is responsible for the operations of the air suspension system and maintaining the vehicle’s correct ride height.

Spoke with Jason, awesome service! Thank You!

Name: | Location: St Paul, Minnesota | SKU: CADF6

We don’t actually have the struts installed yet, but your customer service was awesome. Jason was a pleasure to deal with and took care of everything for us, except paying for the struts…ha. I won’t know about the product itself until it gets installed, but do know that your customer service just can’t be beat.

“I am really satisfied with your product,i didn’t take a photo because it would not avail us of any useful info as you would have to take a ride to know the difference.

Very satified customer”

Name: | Location: Toronto, ON United States | SKU: CADF6

“Parts worked great, good ride so far, easy install, quick shipping, satisfied all around at this point.


Name: | Location: trinidad, | SKU: CADF6

2 questions. Will the car would sit level? Dustin @ SM said that the car would sit level and the “rear too high situation was not a problem with this model”. I asked about the ride and he stated that the ride would be very good. Fact. The car does NOT sit level. It sits abnormally high in the rear. Fact. The car now rides like a truck. Much too firm which is depressing given the availability of modern computer designed components and maddening given that I specifically asked about it in advance. I did not have unreasonable expectations going in to this. I knew the passive components would be a little step down from the OEM system but I did expect that the car would ride at least as well as other modern cars with passive systems. It does not. My passengers routinely make unsolicited comments about it. Dustin was more interested in making a sale than he was in providing truly accurate information about the product and I now regret not having researched more reviews.

“The front struts are slapped together and do not have the camber adjustment drilled out, so basically you have to drill the hole out prior to install.

Customer Service is great when you call to order, but afterwards good luck making contact with them,

The rear shocks are horrible, the car rides like a eighteen wheeler, and takes bumps like a SUV, I would highly not recommend any strutmasters products. I have been contacting them for over 2 weeks and have had no responses.”

Name: | Location: Franklin, MA United States | SKU: CADF6

“having installed a name brand strut on my 2002 cadillac dts i didn’t have proper tire clearance . I spoke with a rep at strutmasters and they had the right struts
for my car they were a snap to install and I had the right tire clearance I would highly recomend these struts over any of the so called major brands sold at local
auto parts stores
well worth the money”
