Can I use stock shocks with a 3/5 drop?

[ScottH]

I bought a set of drop springs for my truck from CPP. 3" for the front and 5" for the back. The truck has brand new stock shocks in it and was wondering if I can keep the new shocks with this drop? I've read some threads that say yes and others that say no. Some have mentioned installing a rear shock relocation kit.

Any advantages/disadvantages either way?

Any info or suggestions would be appreciated.

Thanks
Scott
