Our Mustang II springs come in rates from 275 thru 425 and in 13.5” free height/length. They will require cutting to the necessary length on the majority of applications. For the heavier vehicles such as full size pickup trucks and fat fendered cars the spring rate used will normally be in the 350-400 range. With Small Block and automatic a common rate is 375 to 400 and with the addition of A/C or a big block you will need to compensate for the additional weight and go to the next higher rate. Frame boxing and plating, accessories, and fuel tank size all play a part in selecting spring rate. When vehicle is sitting at ride height ready for test drive the lower control arms should be parallel with the ground or pointing down at a slight angle on the outer ends. The springs will settle some in the first couple of hundred miles so allowance for this should be made.

  • 1800 lb. Front  End Weight = 425 Rate Spring

Notes

Our Mustang II springs that we currently offer are all 13.5” long and require trimming to the length needed for each individual application. Weight rating changes as the spring is shortened. When installing in the vehicle the flat end goes up into the upper had and the end with the “pigtail” goes down into the lower control arm. Spring is rotated when installing to position the pigtail properly. Springs TOO long will have a tendency to NOT sit properly on the lower arms and actually in some cases bow outward causing spring bind.

Some parts are not legal for use in California or other states with similar laws/regulations
