Deaver U402 STAGE 2 Question

I'm looking at Deaver U402 Stage 2 (400-600lb load capacity) but I need more than 2in lift. I'm was looking into pairing F85 overload replacement leafs with the stage 2 to get the lift I need but was told pairing them wasn't recommended. Could I pair the F85 with the stage 1 and get the lift and load capacity I'm looking for?

 

i have the stage 2s with about 500 ish pounds over the rear axle got more like 2.5" to 3" of lift.

 

Hmm maybe because its a second gen?

 

Sounds like a question for deaver. But I had Stage 2's in with 400 lbs in the bed and had 3" of lift.
