Convert Your Existing Mustang II Front Suspension to Coilovers with Zero Modifications

Many Mustang II early adopters used an actual front suspension crossmember from the Mustang II or used an aftermarket budget or lower cost Mustang II IFS kit that usually end up with an OE-style fixed rate coil spring and basic shock absorber combo fitted to their Mustang II front suspension. This style of Mustang II front end used the stock stamped steel control arms. While this worked, it did not allow for ride height adjustment and finding the correct spring rate for your vehicle’s weight was a challenge. Upgrading to a coilover shock system, which provides an easy solution to ride height adjustments, low cost spring rate changes, and better handling, is often the preferred solution.

Retrofitting Mustang 2 front coilovers to the stock Mustang II front suspension can be challenging, as a true coilover shock utilizes a threaded shock body that uses a fixed upper spring seat and an adjustable lower spring seat, eliminating the upper spring pocket on the Mustang II frame or welded component of a Mustang II suspension kit. This design is what gives the coilover shock its ability to easily adjust ride height and swap out spring rates depending upon front vehicle weight and application needs.

To solve this issue, we have created an effective conversion kit to install Mustang II coilovers that requires no cutting, grinding, or welding and is a true bolt-in to stock or aftermarket Mustang II IFS systems at a great value. This Mustang II coilover shock retrofit will work with both stock stamped lower arms and aftermarket tubular lower control arms (both with and without strut rod systems). These are not universal coilovers that require modification to work on your Mustang II front suspension.

Quality Materials in An Easy to Assemble Kit

Our Mustang 2 coilovers are a bolt in retrofit with zero modifications while increasing overall suspension travel. Beginning with an AFCO steel monotube shock absorber, with a fixed valve rate (available in chrome or black painted finish), the correct hardware to make the shock a bolt-in retrofit is added along with polyurethane mounting bushings.

We include the correct length 7/16-inch diameter through bolt for use with stock stamped steel lower control arms or Mustang II tubular lower control arms for use with strut rods. Must be used with 7/16" bolt application unless modification/use of a different bolt sleeve is utilized

The kit includes a slip fit threaded sleeve and retainer that converts the AFCO steel body Mustang II shocks into a coilover-style shock with threaded body. Included with the sleeve is a black anodized lower spring perch that is threaded to make ride height adjustments, along with a black anodized locking collar to maintain your ride height setting.

However, the really trick part of this conversion is our unique Mustang II coilover springs, sold separately. These are wound from premium chrome silicon spring material and available in four spring rates (375, 500, 600, and 700 lb/in rates for various front weights/engine combinations).

We recommend our lightest 375 lb/in springs for vehicles like Model As and Ts, while the 500 and 600 lb/in springs are more suitable for heavier pre-war coupes and sedans. Heavier cars like 60s muscle cars might need to use our 700 lb/in springs depending upon engine size and accessories (AC, power steering, etc.). It is best to weigh your front frame section, engine, and accessories to determine final front suspension weight and choose your spring accordingly.

The springs are tapered so that the upper spring diameter matches the stock Mustang II upper spring seat cup/pocket, yet the bottom of the spring necks down to a standard 2-1/2-inch ID to fit a standard coilover shock dimension, thus allowing a longer spring to fit in place for reduced spring rates and a better ride. Utilizing the factory upper spring pocket also places the spring’s load into the frame, as designed by Ford, versus a single shock mount like most aftermarket coilover conversion shocks, which was not designed to carry the vehicle's front weight and can lead to failure of the upper shock mount in extreme cases. Lastly, the springs are chrome plated to match the coilover shock body and hardware for that show winning appearance.

Direct Fit to Your Mustang II IFS With No Special Tools or Welding

Upgrading to our Mustang II coilovers couldn’t be easier. All you need to do is:

1. Remove your original shock absorber and coil spring

2. Fit the assembled coilover shock and spring into place

3. Secure with the included mounting hardware

We suggest using our Mustang II upper spring isolators to eliminate metal on metal contact between the spring and the frame pocket that could create squeaks or noise during suspension movement if your original ones are damaged or missing.

Once installed thread the coilover spring adjusters up or down to adjust your ride height (our coilover spanner wrench makes the job easy) and even out the left and ride side of your front end and lock the adjustment down and you’re ready to hit the road with the perfect ride height and a great riding shock and spring package.

The kit includes two chrome or black painted shocks and coilover conversion mounting kit. These can be used as service parts to our complete Mustang II coilover kit or used for a custom project/installation.

NOTE: Not recommended for front axle weights more than 1,900 lbs.
