Thread: mustang II spring question

Tweet

Just to emphasize Richard's point there were different factory spring rates for (abreviated example) base Pinto, w/AC, station wagon, etc. Then add the MII 6 cyl, 8 cyl, Those combos w/AC w/o, "sport" suspension, etc. Saying "factory spring" or the "ones that came with it" doesn't zero in much. As Richard said, this is used stuff, and compounding the previous owner's mistakes only complicates things.

One more thing that's a common error with MII's, guys think since they have a V8 and guess that the Pinto/Mustang was lighter they need to get the highest rate Pinto/MII spring to handle it. Very wrong. The heaviest of MII's got almost to 3400#, a Model A for instance isn't going to be close to that. Also the weight distribution was different for the Pinto/MII, their engines were nearly centered over the front "axle" centerline, in rods the engine weight is further back.
