Part Details

  • Set Quantity:   4 Piece

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 

Loaded strut & spring assemblies allow for a quicker, safer install than bare struts.  No spring compressor required! 

Trouble-Free Install

Includes the matched parts needed. New components over reused parts provide a better ride and save you from having to repair again.

Matched Parts

Not all shocks and struts are manufactured the same.  Mixing and matching can result in ride quality issues and decrease the life of the parts.

Saves Time & Money

Over buying the parts individually, or having to search different parts that are correct for your vehicle (because we did it for you!)

What are the rear strut specs I have 17 inch wheels on my car and Ive noticed some of these say 16 in Wheels other say 16 and 17 inch wheels I want to know the specs the measurements of these I want to know what the difference between them are?
Chris G December 6, 2018
If the strut and spring assemblies do not specify that they exclude a particular wheel size for your year, make and model then you will not have to worry about it. However, if they do, you will have to find strut and spring assemblies that specifically state they are for 17 inch wheels.

Strut and Spring purchase
The components were a direct replacement for my 2004 Pontiac Grand Prix. The front assemblies performed well, but the springs on the rear struts were noisy after installation, to the point I had considered removing them. But as I continued to operate the vehicle the noise dissipated after a few hundred miles.

New struts and shocks
The struts and shocks were amazing! My 2005 Grand Prix with 240,000 miles drives better than New. I would definitely let everyone know about this sight. Only wish they came compressed, though I know that might cause some liability in shipping. Still best investment on my car yet.

Great product, customer service, and shipping A+++++
These struts were half the price (if not cheaper) than what I found them for at O’Reilly’s. Being that they come as a complete assembly it was easy installation. The fit was perfect and had absolutely no problems. Got an alignment after installation and to my relief there was no problem with aligning it. Awesome product and it fixed my front end clunk. Rides like a new car now. Highly recommend

2005 Grand Prix Struts
Excellent product, very easy to order and accurate description when ordering. Super fast delivery, definitely would recommend using these struts and spring assemblies. I did comparisons on other sites and 1A was far and above the best deal from price to free quick shipping. I would also recommend getting the sway bars at the same time and replace as well, the combination is a great deal.

Everything went smoothly.

They worked perfectly

Awesome quick-struts!
I bought these quick-struts to replace the worn out ones on my 07 Pontiac Grand Prix and I am very pleased at the quality and performance of these! The free shipping was the best part since every other seller wanted $50 bucks or more for shipping. They are well worth it and very easy to install!
