Detroit Axle Struts - Mazda5
Size: 8AQS1300732/Big Kit
Extremely smooth ride after installation; a complete contrast from the OE Struts that had finally worn out on my Mazda5. Perfect fit and no issues reconnecting the ABS line and the brake line. I also replaced the stabilizer bar links since it was the perfect time to also do that. Also the top of these Detroit Axle Struts can be manually repositioned (rotated slightly by hand) to align with the upper "Strut Tower" (3-hole pattern) bolt locations. Every detail...every design feature is built-in to these aftermarket Struts to identically match the OE Struts. Only time will tell how durable these Detroit Axle aftermarket Struts are. I've used these on other older vehicles and these have worked extremely well. When it comes to installation, I don't know that there are ANY "easy" Struts to install. The beauty of this product is they come Factory pre-assembled with brand new Springs, which is an immediate time saver as well as a safer car maintenance task for the DIY'er, like myself. While that costs more, I myself don't mind paying a little extra for the factory pre-assembled (entire) Strut assembly. I have never had a problem with Detroit Axle Struts. I like the paint quality and the finished look. The only drawback with replacing Struts is getting them perfectly realigned back into the main front (Cast) wheel bearing Housing. I'm talking about a very near "line to line" shaft fit back into the factory machined cast collar. It takes patience, a coating of motor oil on the Strut bottom (about 2") and careful but deliberate use of a smaller (3-lb) sledge hammer. I well imagine that all vehicle makes and models are going to be different for ease of replacement Strut installation. Mazdas are a challenge for absolutely sure, however the immediate difference in ride quality is WELL worth the effort. I've done over a dozen or so of these aftermarket Struts now. I'm still an amateur but I always, always appreciate the immediate difference in ride quality. Makes your older vehicles feel and drive young again. And if you can afford it (and the need is there), replacing the front tires (with a front end alignment!) will transform your vehicle to an even greater, smoother ride. The value is in driving your older vehicle longer before having to finally replace it.

Best price point. Watch the A1Auto videos if you need help.
Size: 10ACQS47152/Big Kit
For the install I would suggest two scissor jacks to hold up the rear swing axle. At least two ton jack and short jack stands. The OE nuts that are 17mm head size are 18mm in the kit. So make sure you have both sizes. My kit didn’t come with the rear shock rubbers and washers. I reached out and customer support representative Steven offered a partial refund. For the sway bar links mine were really rusted and I couldn’t get them to break free on one side. I suggest a 4” grinder and cut off wheel and carefully cut the sway bar link lower stud. I first removed tension on the sway bar. Then cut the sway bar link (don’t cut the sway bar.) I was then able to remove the sway bar link with the strut assembly. With the strut assembly out of the way I tied back the brake lines and carefully, very slow with light pressure cut the sway bar link stud. Then knocked it out with a punch. Wear ear and eye protection. Make sure your vehicle has no grease oil or gasoline that can catch fire and have a fire extinguisher handy. For the rear shocks first impact the upper nut. Then use an Allen key 6mm and a 17mm ratcheting wrench to remove the nut. Replacement nut has an 18mm head. Gear wrench makes a 4 size ratcheting wrench. 16mm, 17mm, 18mm and 19mm. If you don’t have one get one. Best of luck be patient and be safe. Plastic wheel chocks or wheel chocks of some design are a must.

Incredible Value
Size: 10064-8/Big Kit
I agonized about whether to buy these or spend a LOT more on other options. I'm so happy I trusted the reviews and went with Detroit Axle. This is a 6-month review. The old strut mounts were rattling over bumps and the car sat really low. Puddles would make the belt slip and squeak. It still felt smooth and nice but cornering wasn't very fun (body roll). These struts made it all better and I have no complaints about the ride height or fitment. Installation was no problem except one of the ABS wire mounts was finicky. Initially, the ride height was a little higher than I thought it should be but as you can see in the picture, the springs have settled to an even and appropriate stance. The ride was slightly bouncy (but still smooth) at first but a few hundred miles later the car feels smooth as silk and cornering is much better than before. Feels like a Lexus! Even if these only last 2 years, at the price, so worth it to make an old car feel new.

Kit de suspensión delantera .
Size: 10ACQS47152/Big Kit
I’m very happy with this suspension kit for my Toyota Sienna. It includes everything needed for a complete front and rear suspension refresh, including the struts, control arms, rear shocks, sway bar links, and outer tie rods. The parts fit well and made a noticeable difference in the ride and handling. Great value for a complete kit.

Defective Parts and Terrible Warranty
Size: 10145-8B/Big Kit
I installed these shocks and struts around 16 months ago. Originally they were better than the worn-out factory ones but that quickly went downhill. I don't drive this van every day so I had no idea how bad they were. I drove it recently with about 7 people in the van (half were kids so it was not overloaded). Pulling into a parking lot the front and rear each bottomed out. The incline was not very steep so it should not have bottomed out. Later in the drive, I hit an average dip in the interstate while doing the speed limit. The whole van bottomed out, front and rear. It made a terrible noise. Each bump I hit in the road would cause the front to bottom out. My wife drives this van every day usually with no one in the car with her. She says it doesn't do this when empty. She's noticed a few times it bottoming out with only her but didn't think to mention it. Today I call Detroit Axle to file a warranty claim only to find out their warranty only covers half of the order when ordered as a kit. You can get the front replaced or the rear but not both. I decided to go with the front only to find out they only had the driver's side in stock and had no idea how long it would take for the passenger side because an order had not been placed for one. He said it could take 6 weeks or more, he didn't know. I asked how much it would cost to ship, since the customer pays for shipping of warranty claims, and was told $120!!!!! It was $60 shipping for each side!!! You buy a product with a "10-year warranty" only to find out it covers half the product. Then they only have half of that product in stock AND it costs half of the original total order price to ship it to you. As if that wasn't bad enough, I asked the man to direct me to the area on their website that describes this policy and he said certainly, THEN HUNG UP ON ME! I know it seems I'm upset because I am now but I was not at all rude or short with him. I was only trying to understand this policy no matter how poor it was. I would advise anyone to stay away from this particular product. I can't speak for other products sold by Detroit Axel but I can speak to this one and most importantly their warranty.
