Rear Struts/Springs vs Quick Struts

[TheDeal526]

1993 Buick LeSabre Custom 3.8L

Just a quick question about the rear struts and springs on this LeSabre. I understand some LeSabres have and air suspension system, mines doesn't. I have the regular struts and coil springs.

I was wondering could I kill two birds with one stone and replace my rear struts and springs with these Monroe Quick Struts part#171799. I found these quick struts at advance autoparts, here is a link to the struts on their website. http://www.partsamerica.com/ProductD...ype=50&ptset=A

When I call Advance Auto they tell me these quick struts replaces both my orginal struts and springs. Before I purchase them, I want to make sure they will fit in my car, and they will hold up under the weight of my lesabre.

Thanks all for any help.

And Happy Holidays to All

The "Quick Strut" will work only on the front suspension. The rear strut and springs are separate components. If I were you, I would get the Monroe Sensa-Trac air struts for the rear, with a manual air fill kit, Part #AK29.
Or, you could replace with regular Sensa-Trac struts!

thanks HotZ28. when i went to advance autoparts.com and strutmaster.com those quick struts came up for rear strut replacement. I was hoping i would be able to replace my rear springs and rear struts with the quick strut since it seems like it would be alot easier as far as labor. I also contacted an Advance Autoparts store near me and they say I can use these quickstruts to replace my rear struts and springs.

How well will the air struts work if I have worn rear springs?

Well, it appears they do they do offer a “Quick Strut” for the rear of the LeSabre. This is a new product! Pic here

NEW INFO: The rear Quick Strut pic at Advanced Auto Parts was incorrect! It should look like the new link above & below. The quick strut for the rear is nothing more than a regular Sensa-Trac strut with the addition of the upper mount and does not include a spring. You should not need a Quick Strut for the rear unless your upper mount is damaged! Another pic here

If you want to keep the standard suspension, (non-air assist), you can use either the Sensa-Trac "Quick Strut" or the basic Sensa-Trac strut, with a set of new springs found here.

Air struts could be adjusted to overcome any weakness in the rear springs using air pressure to adjust ride height. The price of the "air strut" is considerably less than the "Quick Strut" and you would have more adjustability for load. All Monroe Sensa-Trac struts have a lifetime warranty. You will have to make the choice!

i guess i shouldve took a look at this post before i went and ordered the quick struts. there were no springs with the quick strut i ordered. i decided to just order a new set of springs and sensa trac struts. when i called gmc about the springs they required a code that is suppose to be on the springs itself in order to determine which springs my car takes. they said their were 4 different spring sets, 2 of which are discontinued. advanced auto only had 2 different spring sets. 1. a constant rate spring set (CS5711) and a variable rate spring set (CC661). i ordered the variable rate set, and a set of sensa trac struts (71799). i was wondering, will i have any problems installing the springs? gmc has 4 different spring sets and that has me a little concerned. i can only assume there are 2 different sets for air suspension and 2 different sets for non air suspenension. does anyone have any idea if the variable rate spring set (cc661) will install properly?

I think you will be ok with the variable-rate spring. Here is more info on the difference between straight rate coils and variable rate coils.
