Good afternoon Mike, I recently purchased a 1971 Chevy Camaro with a 350 which someone had installed air shocks and what appears to be a new set of leaf springs, 4 possibly 5 leaf on it. I replaced the air shock with a set of standard premium gas charged ones. Unfortunately the back end of […]
Mike, I am currently restoring a 1971 TA. I plan on replacing the rear springs but am having difficulty determining which ones are correct for my car. First off, all 1971 TAs came with the 455HO motor and F60x15 tires. When I do a search on your website using “Trans Am” under body style, the […]

Mike, I have a stock 1956 Belair which is sitting kind of low in the rear. I have installed new Load Leveler shocks that raised the rear a little, but I need to raise rear another 1-2 Inches. Can this be done with just adding a leaf? The original springs appear to be OK, she […]

Q -Mike, Hope you can give me some direction here. I have an ’81 Corvette that has one side lower than the other in the rear. The local shop replaced the rear tie bolts, but it still is tilting to one side. They think it is the leaf spring and recommends I replace it with […]
Mike, Bought a set of OEM rear leaf springs for my ’70 Boss 302 Mustang. I have no problem with the quality and specs of these springs but, when you advertized OEM correct replacement springs….

Q -Mike A quick questions for you. I purchased springs for all four corners of my ’70 Camaro Z28 last fall and have installed them. About the rear leaf springs, do the bands that hold the leafs together get removed after installing? Or do they stay there? I ask because I also have a ’66 […]
Mike, When measuring a leaf spring, I assume that the front part and the rear part of the spring’s dimensions “When following the curve”of the spring is the same for both a standard arch spring & a high arch spring. If this is true, what happens to the rear shackle? I wouldn’t think that it […]

Is there an advantage to putting multi-leaf springs on a vehicle with mono-leaf springs?
Mike, I bought monoleafs for my truck 8 years ago, not knowing the down side of using them. They sat around for 4 years before I put them on. They sit too low for my taste. To make matters worse, I was sold rear monos with a 6″ drop instead of 4″. Now they are […]
