Each complete strut & spring assembly contains:

  • Upper Strut Mount
  • Strut Bearing
  • Coil Spring
  • Boot & Bumper Kit
  • Gas-charged Strut 

Lifetime Warranty

so far so good
Very fast & free shipping. Prices are way better than going to a local parts store. Installation videos are an awesome addition. All in all satisfied so far, rides way smoother-more comfortable than before. Now for the durability/life span test. (Thats why only 4 stars not 5) Def. Recommend 1A auto to others.

Front Strut & Spring assembly
Ordering parts on the 1A Auto Parts Site is always very easy. This particular order was delivered in good time. The parts were exact fit just as viewed online, and they were very easy to install. The ride and handling of my 05 Chrysler 300 is noticeably much better.

awesome parts and value
Struts were more 50% less than advance, autozone and pelican To save even more the shipping is free, Struts weighed about 30 to 40 pounds, but takes about a week.

Great price easy instal!
The price is the best out there, installation only took an hour and a half using hand tools. The hardest part is wiggling the strut out on the driver side. To give yourself a little extra working room on the removal of the old strut just jack up the car a little bit off the jack stand to give yourself that extra 1/4 inch when sliding the strut out of the bottom.

1st time buyer so far - so good.....
Arrived ahead of time. package was not all beat up.
For what these are, no auto parts store in my neighborhood could touch this price.
Installed. The car rides nice (so far.)
I would recommend these to anyone who might be unsure of these.
Will come back to this company for all of my auto parts in the future
I will be sure to adjust my rating (as needed)

So far so good
The shocks and struts went in just fine and seem to be working very well. It's only been a few days so it's too soon for 5 stars. I will say that the product was delivered in a way that blocked my electric gate after I gave specific instructions concerning where to deliver (see original order). So far so good. This is my first order with 1A.

O'Reilly's web page has extended, compressed & travel length measurements. What does it mean if one says 25" for extended lenght or 17" length & which one fits for a touring edition?
Jay M on Nov 29, 2017
BEST ANSWER: The length is for the strut fully extended or compressed. This is not where the car normally rides. The only difference in struts on 300,s are for the SRT8 and cars with self leveling. The rest interchange between models

Ken T on Jan 23, 2018

Will these work on the R/T?
Pierre B on Sep 23, 2017
BEST ANSWER: Should be fine, only thing is that it doesn't come with a nut fused into the strut for the bottom bolt so you gottta hit a hardware store for a nut. Look at the struts on the dodge on the bottom and you'll see what I'm talking about. There's a nut that catches the bolt. I've got an RT myself, I got the struts for my brother's Chrysler 300.

Ken T on Jan 23, 2018
