Description

The 1″ spring  perch move improves the motion ratio,  Opentracker Track Roller Spring Perches on control armadding another small upgrade to the ride quality and handling of a 60-70’s era Ford or Mercury. This photo shows the perch move on our 65 Mustang/Falcon/Comet roller upper arm with a double roller spring perch.

Changing to a more favorable motion ratio allows you to use less spring rate to do the same job.  The shock is utilized more by the increased travel over road conditions. Both are gains for the performance driven classic.

Depending on current spring rate, the perch move will increase the rate by 100-125lbs. It will also raise the car about 1/2″.

This upgrade is for the road racer looking for every little bit of gain available. It does not make a big change like the 1″ upper arm drop. It makes a slight improvement in ride and handling.

We have had some clearance issues with the perch move. On some aftermarket upper control arms, the stamping is not like the original Ford or Opentracker control arm and requires modification. Call or email for details.
