Each complete strut & spring assembly contains:

  • Upper Strut Mount
  • Strut Bearing

  • Gas-charged Strut

Chineese parts on a ford....
Well the coil springs are too long and there is no air between the coils which gives the vehicle no bounce at all. I ordered front and rear and it looks like they put the rear spring on the front which is longer. I complained to 1a and they sent me the same front struts again.
I had to take them apart and use my old springs which defeated the purpose of buying loaded struts....
I new better than buying cheep parts. If you don't pay 100$ a piece hour backing up.
Why put Chinese parts on a ford.

The product is good. I have been ordering from here for a while now. But, this last order got screwed up. Waiting for parts cause they forgot to pull them. ?? Next day delivery? Took over a week for mine. I asked why they forgot to pull the product. Answer..... you had a large order. Are you kidding me? You didn't just say that. Idk if I will continue to order.

The ride quality is superb can't be happier with the price and again with the quality! My wife and I did the fronts and took it in to a local shop and had them do the rears. We still save almost over $750

Can thsee be adjusted any at all to lower the truck?
Jeff H on Mar 26, 2017
BEST ANSWER: No, these are meant to be used to factory height and are not adjustable.
Would these fit a 03 Lincoln aviator as well?
Scrappy on Mar 28, 2016
BEST ANSWER: No they will not
Are the just the replacement or will these give me a little bit of a lift to the car?
Mariah M on Mar 11, 2016
BEST ANSWER: I got no perceptible lift after installation, nor did I expect any. I would guess if you have a broken spring you may notice some lift where that spring has broken. My reason for replacement was due to leaking shocks. This complete strut made for a quicker and cleaner install. My son and I installed all 4 in about 4 hours using a lift. Neither of us had done this job before. Some delays were being cautious and double checking torque values etc. Car rides nice now.
