Torsions springs for SC4

i have an 05 mach z. i called ross at hygear and he hooked me up with a new set of rear torrsion springs. i told him my weight and sled and what i was using the sled for and he sent me a set. noght and day difference over the stock springs. when it comes time to rebuild my shocks i am definatly going with hygear. i am also considering doing his dual rate springs for all my shocks.

I have upgraded to 503-191-247 and 249. they are a little weaker than my SC3 674 675 springs, but much better than stock! Someone has recently posted a spring chart that may help.
Looks like all the CS4 springs are square. There is less room in the SC4 so most of the springs have less coils.
good luck.

Re-posting as I cant seem to get any real feedback. Has anyone upgraded their springs on the SC4 skids? IF so, can you give me a little feedback on what you used (size) and how it performed?

Thx

HyGear sells springs of all weights and so does Toms Performance & Service.
They will tell you all you need to know.
