cool Burban! cant wait to get my 70 K/Custom done...

I put these on my 55 Chevy, along with the tubular control arms, front sway bar, and power front disk brakes. It now rides so much better than it did in its stock form.

You should do a video on how to setup spring preload on the promastar coilovers.

does it get into 2008 tahoe

How long did the job take?

Put that big Mark Mickey radial tire on the car Alex at sick week and you will be running 5s in the quarter!

Max is a very knowledgeable young man! Great on camera! Hope to see him on more often.

I was hoping that raising my front 2.0 fox coilovers would help stop the front shocks jump every time I go over a sharp bump at slow speed .

I have an c30 Dooley I already have a lowered spindle and dropped coils 3 inches for each one, but I want to put some of your coil lovers upfront to get more drop. What size and rating should I get?

When your IT department does your install video...😊

There are enough mods needed to the body of the car for these? I've seen some coilovers installed that requires cutting a hole in the car near the top of the shock for clearance. Not sure if the inverted shock design fixes that.

What about with 4 inch lowering control arms?

I need this for my 85 Sierra c3500.

So on a single adjustable, I can still change both stiffness and ride height?

Is this the same installation for a G-Body

Awesome ❤❤❤

i have a fully adjustable customized magride in my 2018 Audi S3, with 3 way adjustable compression rebound. (low/med/high shock speed.) i dont like the harsh bumps over cracks around town. i think i will dial back my compression for low speed shock setting (< 2.5" rod trravel). thanks for the thoughts, you got my project going.

Do you have to use a upper bushing on the top of the coil over spring where it contacts the fram

How much room do I have in the rear for tires? What offset with a narrowed rear differential?

But can she cook?

I think this how you calculate unsprung spring rate or what spring you need. So if your rear end was 1500 pounds and you subtract tires, axle, brakes, etc and you end up with 1200 pounds, your spring should be able support that weight without bottoming out. So if you take 1200 and devide by 4 you'll get 300 So you need a spring with a rate of 300 or a longer spring. This would be 25% compression for a 16 inch spring. 450 pounds in the example seems like a small amount, unless he was referring to a small car?

*promo sm* 💕

good to know thanks

Do the coilover system come in RHD for Australian vehicles?

Wish i could afford the coil over shocks adjustment for my 83 montecarlo ss

Curious if there’s a rim and tire size guide for this kit?

What’s the weight difference complete change over from k-frame?

😊😊😊😊

I'm wondering how much clearance is left between the control arm and bumpstops? Currently my truck is so worn out I'm running about 3/4 of an inch on one side and riding the stop on the other!

Need this with the steering rack setup

If lowering blocks are not a good option what is

I have a question: How do you install a QA-1 rear sway bar with a ford 9 inch (Quick performance)on a B-body with QA-1 stage 2 suspension kit??

great video! I have a question 3:09 , 10:45 - is it just polyethylene or an air bag? what is it for and what function does it perform?

Is this fox running the QA1 - MUK21 subframe? I’m in the process of a 5.3 swap into my 93 and I am looking at this subframe currently

i seen senarios where the coilover raised the front at lowest setting and 2" spindles had to be used.

I may be wrong, but don't you lose 2" of suspension travel using coilovers or drop springs? Won't that increase ride harshness over what you'd get with drop spindles and stock replacement or even performance springs? Would stock height coilovers and drop spindles be a better, though more costly approach? If not, why not?

I have a stock 1989 C1500 and I have 22 inch weld wheels . What would you guys recommend? I don’t want to have to cut any fenders.

Great product! I just got the new Promastar struts for my 1991 Camaro (drifter). wish you had more videos with 3rd gen Camaro parts, 3rd gen forms have a big following :)

How do you calculate the motion ratio if the shock absorber mounts directly to the knuckle?

Very straight foreword!! Thanks, I will be ordering my set tomorrow.

I have no doubt I'll have parts available for the CV decades from now. The QA1? QA1 is the only one who makes parts for the QA1 suspension. If I need a new control arm 30 years from now is QA1 going to have it?

Question: I am on the edge of almost ordering QA1 coilovers for my 01 Silverado regular cab. I want to achieve a 4/6 drop . Do I also need a drop spindle? Will be my daily not for any racing. Do you recommend the 650 springs or the 750?

$700 dollars for 2 shocks ? I'll pass !

I have a old body crown vic i think that these coilset ups may fit

When did Qa1 change from the closed cell foam pad to the gas bag? This morning, I tore down a pair of 50 series twin tube shocks that are over 20 years old that still have the foam.

Isn't truck arm supposed to not require a panhard bar? Trying to figure out a simple solid axle suspension geometry without a lateral locator. Pinion angle is unimportant as I'm building a de-dion suspension which mounts the diff to the chassis and uses CVs to power the hubs.

What compressed/height did y’all use for that truck?

I'm soo tired of my coilovers i can't get them to stop bouncing

Ok, so when i do this to set ride height, the rear bounces like worn shocks and hits hard as brick, so i move the shock up one hole and readjusted ride height and get same thing.....whats my problem???

you confuse sag vs spring rate vs spring resistance......you can compress a spring until it binds and it won't affect spring rate. Most people don't understand what spring rate is or what sag is either. Increasing the spring preload definitely increases the spring tension or resistance. It will be stiffer at the same amount of wheel or shock travel. That's pure physics. What you failing to mention when you are talking about the sag is that there will be less of it available. In the sceneio you are talking about it may not be noticeable UNLESS the customer is at the end of the available sag. More importantly what the use of this type of system you and everyone else is avoiding is whether or not the shock is rebuildable and revalveable. I would not spend the kind of money this type of system costs without this feature.
