Meet the Unsung Hero of Mustang Suspension
We started with our reinvented MOD Leaf Springs, then we reinvented them again, giving you the easiest way to slam a 315 under the rear of a classic Mustang. Inspired by the old trans-am race cars, our narrowed leafs are a scant 1 3/4″ wide with a slightly stiffer spring rate than our standard leafs, but offer just as much strength, responsiveness, and ride quality as their wider brothers. The gallery shows the size difference between the two leaf springs we offer.
So what’s it take to get a 315 in the back? You’ll need to mini-tub the car, pushing the inner wheel well up to the frame rail (which will pick up about 3/4″ clearance), and you’ll likely need to roll the quarter lip. That’s it. No welding bracket to your floor or rear end housing, etc. You may need to slot the openings on your leaf spring pads, or, if you add a set of lowering blocks to your order, we can make them offset for a super clean install.
Mustang leaf springs tend to get a bum rap, but that’s only because the typical designs out there are circa 1975. We’ve seen people buy a set, be disappointed in the results, and blame it on their 50 year old car. But that’s simply not true. When we bring modern technology and design to leaf springs, we can create a rear suspension that performs, installs simply, and keeps down the weight.
These leaf springs include the narrowed bushings and shackles you’ll need.
After installing these I am impressed, wow these are heavy duty. Great construction with a hard wearing coating. I am looking forward to completing the suspension and seeing how these bad boys improve the handling.
