Need help from the suspension gurus here!

Is there a reason you went with 10" springs? I'd think 12"-ers would give you more travel and help free up the front end some. Looks like there's plenty of room on those shocks for 12" coil springs.
I didn't choose them. They were supplied with the kit. I was never asked about springs, and I wouldn't have known what to specify anyway. Like I said suspension setup is voodoo magic to me.
