Comparing QA1 C10 Coil-Over Systems: Which is Better?

QA1 has two types of coil-over conversions for C10 trucks: one designed for the stock crossmember and another with a fully engineered crossmember. Both kits offer a lowered stance, adjustable ride quality, and improved geometry. However, there are key differences between the two kits, including the amount of drop and the steering system. Overall, these conversion systems offer a perfect solution for truck owners looking to improve their ride quality and performance.

You read our minds with the timing of this video! Getting ready to do some pre Power Tour upgrades on our '65 C10! 😮

[@PEDR0SKI]

I've had my qa1 coilovers front since 2020, rear kit since 2021. Qa1 crossmember going on in a few weeks when my slot at my buddies shop up. 😎

[@QA1TECH]

We appreciate you choosing QA1!

Just picked up a 71 c10 and likely this is the route I’m going once my wife lets me spend the money lol.

[@QA1TECH]

Tell your wife it's not spending money, it's investing in your happiness 🙂

@@QA1TECH hahahahaha I wish it was that easy. I will be buying sooner than later and cannot wait to feel out the truck on the coil setup.

[@QA1TECH]

@@dlew913 Good deal, let us know if we can help! Remember, you can start with the system for use with the stock crossmember, and add the tubular crossmember later.

[@networx2002]

I would love to see some pictures of the stance once the QA1 coilovers are installed. I want to see what the stance looks like before I decide on coilovers vs. Bags

[@QA1TECH]

We appreciate the feedback! The crossmember kits allow up to 8" of drop while just the control arm and coil-over kit allow up to 6" of drop with drop spindles.

[@hexthank]

What options are there for lowering the rear on coil-overs past the 6" mark? My truck is currently 5.5" up front and 8" in the rear on coil springs. Can I get that low in the rear with the QA1 rear coil-over kit if I use blocks on the axle housing mounts or maybe longer lower shock mounts?@@QA1TECH

[@QA1TECH]

@@hexthank Our 63-72 kit offers up to a 6" drop and our 73-87 kit offers up to a 7" drop in the rear. I would recommend reaching out to our tech team for some recommendations. 952-985-5675 or [e-mail]

We are really interested in putting this on our 1974 Supercharged Squarebody. We are looking to drop some weight from the front end and are looking for the new car feel.

[@luckysgarageshow]

Lets get this going!

I have a 72 c10 Have the whole qa1 kit front and rear with the tubular system. If I put my tie rods on the bottom of the spendles, the rods from the rack and pinion hits the sway bar. I have the sway bar slid all the way toward the front of the truck . Any ideal?

[@QA1TECH]

Hi there! Thanks for reaching out. We need a bit more information on the setup to make a recommendation. Please reach out to our tech for support! They are available M-F 9am-5pm CST at 952-985-5675 or [e-mail].

70 C10 Stepside...Why do the spindles need to be from a 73-87 c10 for the tubular arms to install? Will i need to also purchase other 73-87 c10 suspension components for this to work? I'm also interested on the whole rear suspension kit with tubular trailing arms...is a c-notch required? I will be lowering my truck 6“ max if that.

[@QA1TECH]

The spindles need to be 73-87 because the ball joints we provide with these kits are a 73-87 ball joint. As long as you purchase the kit for your year range, it will work just fine. Yes, the rear kit comes with a c-notch.

[@Cristo12344]

@@QA1TECH Is the c-notch required at all? Or does your kit allow for no notching?

[@QA1TECH]

@@Cristo12344 The c-notch is required.

[@wyatt9841]

Can these get a higher lift like stance for a c20 or at least stock hight ?

[@QA1TECH]

The control arm, coil-over setup we currently offer for the C20 will lower the vehicle at minimum 1".

[@wyatt9841]

[@JasonVenable-dw9fs]

Would the tubular crossmember possibly work on a 73 C20 Suburban?

[@QA1TECH]

Hi there! The Crossmember will not work on a C20 at this time. We do however offer the control arm and coil-over setup for the 67-86 C20. www.qa1.net/automotive/suspension/classic-trucks-conversion-systems/1967-1986-chevy-c20-1987-1991-chevy-r20-coil-over-front-suspension-kits

Thanks for the reply, will definitely pick up a kit asap.. Any plans of a tubular kit for the C20/30 in the near future?
