I used 7" free length springs on my setup with 900lb/in springs. Probably should have gone with 6" but was able to get the 7" ones to work.

The corner weight and spring rate will affect the free length needed. iirc, SPL had a excel sheet calculator that could tell you what length spring you need. You probably just need to look around on their website or give them a call.
