Difference between SS and HD springs?

Hi,

I've searched the board but can't find a discussion on the difference between HD and SS springs. I'd like to know things like spring rates, ride height, which is more applicable for a street/strip car.

Thanks

HD springs will be better in a street car ...

Of course you are leaving out one important tidbit of info ... uuuummm , what car ???

'71 Charger - 440, 8 3/4 with 3.73 gears

Stock Hemi XHD springs top; SS springs and perches bottom:

Rear of car with stock hemi springs;

rear of car with SS springs;

Suffice is to say that now my SS springs and hangers have joined all the other parts that are incorrect or didn't work for one reason or another. More "garage art"!

xhd springs are stock replacements, have no arch at all when the car is sitting on all 4 wheels, and they make the car sit as low as they did when new.

ss springs have noticeble arch, require longer front hangers on a B or E body, and (in most cases, depending on part number) make the back of the car sit higher than stock.

For handling, xhd. For launch and handling, xhd with cal tracs. For launch with no traction devices and a slightly higher center of gravity/slightly worse handling (in most cases, depending on part number), SS.

I have 454/455 ss springs on the gtx, they work great

Which springs (part number)?
Which front hangers (part number)?
They look like E or A body springs to me/wrong ones for the car
