Narrow Leaf Spring Upgrade

Upgrade your MOD 1 Rear Suspension kit with the unsung hero of Mustang suspension, our narrow leaf springs. We reinvented our standard leafs, 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.

    Description

    Designed with simplicity in mind, our MOD 1 Rear Suspension Kit brings together all the essential elements of a well controlled rear suspension to your ride. The feel is sporty, but not punishing: our goal has always been to instill confidence and responsiveness whether your preferred parking lot is filled with cones or grocery getters.

    Our complete kit includes new performance tuned MOD 165# leaf springs, our panhard rod kit with an optional rear sway bar for adjustability, Bilstein performance shocks, all new bushings, shackles, and U-Bolts. Add a set of lowering blocks to help bring the rear down and dial in the stance. These pieces are all designed to help keep the rear planted and stable, while offering you the flexibility to dial in the feel you’re looking for on those weekend autocross or track events.

    Installation wise, we’ve aimed for a package that is minimally invasive. The only required welding is the panhard rod bracket, the rest are bolt in parts. Some changes may be required to your exhaust if you have an over-the-axle setup. No cutting up floor pans, changing mounting points, or even welding to your rear axle. This kit is designed to perform without making massive changes without having to cut up your car and works with both 8″ and 9″ rear ends.

    If you’re looking to upgrade the shock to an even better option, this kit is available with JRi Shocks.

    The MOD 1 Rear Suspension Kit Includes

    • MOD 165# Leaf Springs
    • Our updated Panhard Rod Kit (found here) with Optional Adjustable Sway Bar (not recommended for street only cars)
    • Bilstein Rear Shocks
    • MOD Leaf Spring Plates
    • Polyurethane Front Eyelet Bushings
    • Rubber Shackle Kit
    • 7/16″ U-Bolts
    • Lowering Blocks (Optional-Recommended for 1964.5-1966 Mustangs)

    Please note: these kits are made to order and per your specifications. Upon order we will contact you to confirm details and provide you an estimate build time. Shipping costs will be added to your order upon completion.

    2. Rated 5 out of 5

      Unbelievably difference. Unbelievable!! Rear end back snaps into place, car squats and go’s instead of fishtailing. Astounded at the improvement the MOD1 rear suspension kit made

      This kit is Fantastic and looks great! Installation wasn’t too bad, definitely harder to find a welder than the actual prep and installation. If you are tired of a sloppy old rear end like me, tighten it up with this kit!

      I installed this on my 1968 Mustang to replace the old stock leaf springs. At the same time, I also installed Mike’s subframe connectors and the X brace. The installation was smooth, I reached out to Mike Maier Inc a time or two with questions and they were very helpful with answering my questions. I use my car mainly for cruising with an occasional burnout or two. The car handles much nicer now, and it just squats and goes under hard acceleration. I installed a 2.5″ dual exhaust after I put the above-mentioned parts in. The X brace and Panhard bracket make installing the exhaust a little more challenging, but it was my first custom exhaust fab and I was able to make it all fit well. I’m very happy with the results and these parts are built very well. Thank you!
