Speedway Motors 7211000 Details

These kits provide the highest quality performance characteristics for your Mustang II front end. The springs are designed specifically for use with the QA1 coil-over shocks and the factory upper spring pocket. This enables the use of a longer spring, which allows for a lighter overall spring rate. By building the upper section of the spring to factory dimensions, this puts the weight back into the frame instead of on a single stud.

Single (rebound) adjustable valving
Billet aluminum body
Developed for high performance with increased travel
Unique piston rod design provides shorter compressed height to allow lower car ride height
Easy bolt-in installation
Includes 2 shocks, mounting kit, 2 chrome-plated springs (choose specific rate)

NOTE: Not recommended for front axle weights in excess of 1900 lbs.

This unit look's good, easy to install and best of all I cans adjust my front end to the height I wanted. I have a 1934 Ford 1 1/2 ton Pick-up and her front end was always higher than the rear. With this install now the front end just right.. If I find I needed to lift the front end, I just raise her to the height I needb

Replaced cut down coil springs and non-adjustable shocks with these to allow for more ride height and shock adjustability for occasional trips to the drag strip. Good quality parts, easy to install. And they work great.

I have settled on buying this kit for the front of my Cobra kit car I am building (a Classic Roadsters AC Cobra) that uses a Mustang II front suspension. I am trying to determine the best match for rear coilovers. I have been looking at the QA1 Pro series (RCK52344 or RCK5348) or QA1 Proma Star (RCK52346). My car has a big Ford 9" rear end. The car will be mainly used on the street with some autocross and weekend road track races. I need help selecting the rear coilovers. Any help would be appreciated!

I have a 1950 Chevy 1/2 with a Mustang ii IFS with the steel stamped control arms and utilizes a strut rod. A 5.3 ls motor and automatic tranny have been installed. I am wondering if this coil over conversion kit will work on my truck without having to replace the Mustang ii lower control arm with strut rod. Seems like using this coil over conversion would transfer a lot of weight would from where the spring rests on the lower control arm to shock mount on the lower control arm. Thoughts?

I have a 1933 Ford Sedan SBC350 MII IFS and replacing control arms with your stock MII kit plus 11 inch Brake upgrade using stock spindles. I am considering this kit to replace stock spring (cut and stiff) and shock while at it. The current spring is cut and about 8.5" free and only 8" compressed and leaves only about an inch of travel for the Gabriel shocks. I want a bit softer ride and it seems this kit would be a match. Would the 375 spring rate give me to much travel or would 500 be better? The 8 1/4 free length of the spring concerns me a bit. I just want to change the ride and don't want to raise the stance but would be ok with a 1/2 to 3/4 inch drop.
