What's in the Box

Info

Don't you wish you had adjustable coil-overs on the front of your classic car to vary the ride height and road feel? This QA1 Pro Coil Adjustable Front Coil-Over Conversion Kit will do just that for you. You get two adjustable coilover shock assemblies that have a single knob with 18 valving options and two coil springs. 

Choose 350 lb., 450lb. or 550 lb. rate springs.

  • Easy bolt-in installation
  • Remove the existing shocks and springs and the QA1 Pro Coil System bolts right back in
  • Springs designed so that the lower end sits on the coil-over shock and the upper end sets in the original spring bucket in the frame
  • Allows for a longer, lighter spring for more stored energy, offering increased weight transfer
  • Greater durability by locating the spring pressure in the frame and not on a single stud
  • Threaded aluminum body allows easy ride height adjustment
  • QA1 Pro Coil shocks are revalveable and rebuildable by QA1 Authorized Service Centers
Fits
  • 1967-69 Camaro/Firebird
  • 1968-74 Nova

Huge Inprovement

April 23, 2016
Put these on my 1970 Nova along with the tubular a arms from speedway. The bolts that come with the coil overs are to big for the arms, solved that with smaller ones and some washers. Car has a 383 stroker, went with the 450 spring rate, seems a little stiff, but then again I haven't driven the car much since install, or made any adjustments to the nobs. As for the performance, it's a huge upgrade, rides really nice. Handles corners so much better. These really tightened up the car, feels like night and day difference. I'm extreamly happy with the value, and quality of these QA1 coilovers! Buy some, you won't be disappointed.
Pros:
  • Great Price
Cons:
  • Wish They Had More Spring
Yes, I recommend this product.

PROBLEM SOLVED / easy swap/great results

June 16, 2012
Just finished a two year project building a 67 Camaro that started out a gutted rolling shell. Unlike the current trend of lowering the vehicle I'm old school and actually prefer just the opposite. I researched the front spring options and went with what was supposed to be the beefiest available, big block, A/C convertable springs. After installation the vehicle sat exactly the way I wanted it to. In fact the clearance was so good that when I ordered the rims and tires I jumped the front tires up 2 sizes. At this point the vehicle hadn't been driven but was moved around the shop and was on and off the lift numerous times. First initial test drive around the block however, and the front end dropped so badly that not only were the tires rubbing but I couldn't even get a floor jack under the front main crossmember. I double checked the invoice almost hoping I had ordered the wrong springs but that wasn't the case. My vehicle does indeed have a big block but it's a standard coupe without A/C and it has aluminum heads, aluminum radiator and an aluminum serpentine kit. I did not want to try another set of coils with the risk of ending up with the same results so I searched for other options. I ran across the QA1 coil over set up on the Speedway site and I could not be happier with the results.
Yes, I recommend this product.

Since your car is complete and drivable I would highly recommend that you weigh the front end to get the best recommendation of spring rate. For these coilovers the spring rate recommendation per front end weight is: 350 springs - 1700 to 1900 lbs 450 springs - 1900 to 2100 lbs 550 springs - 2100 to 2300 lbs As a good guess I would suggest 350 lb springs for a nice ride or 450 pound springs for better handling. Keep in mind that with these coilovers you will have some adjustability in ride height with the coilover adjuster nut. Normally you are able to get the ride height anywhere from stock to about 2" lower than stock.

Will Qa1 coilovers work with 2" drop spring pocket on right stuff detailing tubular control arms PART 3 Q #1 -- 1969 nova ss small block no A/C with power steering, i am installing the above mentioned control arms and they have a 2" drop spring pocket. will that be within the extension range of the threaded ride height adjustment or will i be losing to much travel to extend it down that far? also what spring rate would be ideal? thank you A #1 -- On the QA1 kit number 72146711 the shock dimensions are 9” compressed and 12.75 extended so the suggested mount length would be in the 11” range. If you have a 2 inch dropped spring pocket the shock would be max extended before reaching the control arm and with the weight on the vehicle the control arms would be pointing up dramatically effecting steering geometry. Spring rate wise the 350 handle the basic applications as you describe. To try and use with the dropped spring pocket will not work satisfactorily. Q #2 -- Can this be done if you use a shock extension? If so what kind will work for a 69 Camaro? What do you recommend? QA1 9029-164 ?? A #2 -- On the GM coil over conversions for the front the coil spring still sits in the upper spring hat so using a shock extension on the upper shaft will not benefit the offset of the lower shock and spring pocket. You would also need an upper spring spacer 91645551. PART 3 Q #3 -- I have Proheader Upper and Lower Control Arms. They have the lowered spring pocket all of them have. I want to run the QA1 Coil overs with them. So if the above questions say the shock will not work with the lowered spring pocket, And I don't understand how the spring spacer makes up for the shock length?? can you tell me what I will need and exactly what to purchase?

These shocks are in no way intended for a dropped pocket control arm but I may be possible that you could make them work with them. The shocks in this kit are 9" compressed and 12 3/4" extended. This kit will yield a stock to 2" drop in ride height if using stock control arms so the reference to a spring spacer would be to get the ride height up to this range. It is possible that you could use them without a spring spacer however there is a possibility that you will not get the ride height you desire. Take a measurement from the frame mounting point to the lower control arm mounting point on your car at the ride height that you desire. If that is very close to 11" then this shock will work. You would be best off making spacers for the lower mount in order to get to 11" mounted length of the shock if you want to use this kit. Sorry there is no simple answer to your question other than "no this kit will not work with your control arm". However with some imagination and modification I would bet they could be used, it's not going to fall together without thinking though.

Bolting shock to control arm I am installing this QA1 kit with Speedway's 91036769 control arms. Should the shock be bolted to the upper or lower side of the control arm - or does it matter? The control arms have nuts welded on the upper side - should these be removed to install shock?

The T-bar of the shock will sit against the bottom of the lower control arm. The nuts are welded into the control arm so that you do not have to try and fit a wrench inside it to tighten the bolt.

Part # 72146711 If the Camaro is basically all stock the 450 springs will handle up to 2100 pounds on the front. If you have A/C and/or some other options then you will need the 550 springs.

That kit part # 72146711 is made to work on the 68-74 Chevy nova. I do not think it would work for your 64 Falcon. You could research the differences between the Nova and your Falcon and determine if it might interchange.

Looking at this kit the small block spring rate would be 350lb spring rate. I have installed a LS engine with aluminum heads. Would the 350lb spring rate have enough adjustability for 1" lower than stock stance and later add a A/C compressor later?

The 350 spring rate would be ok if the car is simply a driver that the best ride quality possible is desired. For better handling and if the car will be driven aggressively we would suggest the 450 spring rate.
