Overall Assessment

Customers have highly praised the product for its superior quality, practicality, and main features. The adjustability feature in particular has received commendation from users for providing convenient customization of ride height, improving the stance of vehicles and enhancing ride comfort significantly. The coil-overs are well-constructed and durable, adding to the product's practicality and user satisfaction upon installation. In comparison to competitors, these shocks offer a markedly better ride experience, including outperforming RIDETECH's AirPod system, and are considered an effective replacement for lesser quality alternatives. Despite some lack in the inclusion of certain tools and detailed instructions, the overall consensus reflects positively on the product's performance and quality, with several customers expressing their intent to purchase it again. Special mention was made of high satisfaction from customers who have installed these shocks on model A's and older vehicles implying a great fit for classic automobile modifications.

I put these on the back end of 650+whp truck. They improved my ride greatly over the old race shocks. I didn't have any wheel hip before but still don't with these. I wouldn't mind getting some for the front in the future as well.

Looked great and the ride adjustability was nice to fit my taste. Being able to adjust the ride height was nice to give my 39 ford pickup the stance I wanted.

89 mustang Foxbody SSP wanting to use Qa1 175 lb in front and not sure about the rear 110 or 130lb

by Jabo

Hey all, I need some help determining spring rate for my 59' F100 front end! Im planning on putting a set of these on the front of my 1959 f-100 hot rod. The truck is mostly gutted except for the essentials, it has a speedway 4-link kit in the back with 11" QA1 coilovers with 300lb spring rate. It has a mustang II front end kit (installed by previous owner), 2" drop spindles and has a 5.0 V8 in it. Im looking for 14.5" (or something close to that) at ride height from bolt to bolt on the front coilovers. I looked at the provided literature and am thinking about ordering either the 300lb or 350lb spring rate. Can anyone comment on the proper spring rate range for this set-up ?? (I know it can be highly variable) Thank you!

Gary with the 55 Chevy Belair back again. Length is 17 inches bolt to bolt. Normal ride height. Do you have a coil over shock at this length?

I have a 98 dakota RT that I recently did an 8.8 axle swap and a triangulated 4 link. I can mount my upper shock mounts anywhere so that's not a concern to me. I'm having troubles figuring out what rate of coil spring I need for 650-700lb of weight that sits on the axle.

I got the QA1, 300 series coil overs for the rear of my 68 Chevy truck. When I try to mount them, the spring hits against the axle housing. Is there a replacement bracket that moves the mount hole forward?
