2004-09 Toyota Prius Strut & Spring Assembly - 1ASSP01014

In the past, replacing struts required specialized tools to compress, remove and transfer the old spring and mount.  Pre-assembled with all new parts, our complete strut and spring assemblies make this job much quicker and easier for the do-it-yourself mechanic.

Each complete strut & spring assembly contains:

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

Pre-assembled, loaded strut & spring assemblies allow for a quicker, safer install than replacing with just bare struts. 

Trouble-Free Install

Trouble-free install includes the matched parts needed to get the job done. New mounts, bearings, springs and hardware will provide a better ride for your vehicle and save you time from not having to do the job again because a used part failed afterwards.

Matched Parts

When you buy the kit pre-built by us, you can be sure that the parts are matched for optimum performance.  Not all shocks and struts are manufactured the same, so mixing and matching can result in fit issues and potentially decrease the life of the parts.

Saves Time & Money

When you buy one of our kits, you not only save money over buying the parts individually, but you also save time having to search for all of the different parts that are correct for your vehicle (because we did it for you!)

Lifetime Warranty

This item is backed by a Limited Lifetime Warranty. In the event this item should fail due to manufacturing defects during intended use, we will exchange the part free of charge (excludes shipping charges) for the original purchaser. Please keep your invoice for proof of this warranty.

New spring in my cars step
So far they are great. Car handles like new again. And here I thought the roads were getting bad lol. I was shocked how much better the ride was. As a diy home wrench turner I particularly liked the bolt and go nature of these, no messing with spring compressors. We'll have to see if they hold up but so far I'm pleased.

Rear Struts Didn't Fit Well
When I went to install the rear struts, I noticed the shape looked a bit off from the OEM struts I just took off. The metal loop at the bottom (houses the rubber bushing) appeared to be welded on at a slight angle compared to the OEM strut. This tilt was much more pronounced on the right one than the left. When I installed the left one, it took some forcing to get it to fit onto the car. When I installed the right one, I literally had to grease it up and pound it into place with a mallet. For comparison, the OEM ones I replaced slid on and off the car effortlessly. When I went to do the front struts, I got the old struts off only to realize the front right strut I had received was defective and had leaked all its oil out in the box. There was no apparent damage from shipping. I contacted customer service at 1A and they promptly shipped a replacement which I appreciate. Otherwise the front struts went on without trouble and seem to be decent quality.

Totally satisfied
The right front strut was very tight but it did work.

Are these units total direct replacements? Are any additional parts required or is it simply remove the old struts/shocks and install these? Thankyou
