    Description

    These aren’t your typical leaf springs

    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, then 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.

    The most common complaint associated with leaf springs is wheel hop, the chatter you feel when accelerating. Poor leaf spring design allow the front half of the leaf to deform/deflect causing axle wrap up which snaps back and induces wheel hop.

    That’s why our springs have been designed with an extra two leaves toward the front, with a beefy wrap to add additional strength. We have guys with 900+ hp applications running these springs and they’re still not experiencing wheel hop.

    The other big complaint we hear is ride quality. More often than not, people end up selecting a solid or urethane bushing for the spring saddle which we’ve found to be problematic for two reasons. First, it makes the ride extremely harsh, and second, it actually binds up the rear and prevents the suspension from working well during cornering.

    For a stock setup, leafs have two jobs: they move up and down to absorb shocks, but they also move side to side, working to keep the axle centered. During cornering, the leaf is moving both up and down, and side to side, absorbing bumps through the turn without knocking the car off course. Replacing the bushing with a solid material prevents the spring from moving side to side, increasing bind and ultimately resulting in unpredictable feel. That’s why we actually prefer the stock rubber for the leaf shackles as it allows the suspension to do it’s job.

    We do recommend and include a urethane bushing for the leaf eyelets, as this helps to keep the car under control during acceleration and braking far better than the standard rubber.

    We’ve also intentionally recurved the spring to bring the ride height to what we consider to be the best, about 8″ from the pinch weld to the ground. This slightly lowered setup puts the suspension in the best place for overall geometry.

    We’d also recommend upgrading to our panhard setup to help further control the side-to-side movement of the rear end.

    This setup is a simple, budget-friendly option that is highly effective both on the street and track. We’ve seen dramatic improvements in feel, responsiveness, and ride quality by simply replacing stock or other aftermarket components with this setup.

    1. Rated 5 out of 5

      pauljbrice – November 30, 2020

      After installing these I am impressed, 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. One of the biggest parts of buying these products is not only the quality and design that goes behind them but the support you get from Mike and his team is second to none!
