2011 F150 SuperCrew 4WD-LIFT Question

[BagBat]

Question (for friend of mine)
2011 F150 SuperCrew 4WD.
I need a lift.
Putting 33x12.50x18 MT tires on it.
I need:
2 inches in front to clear.
No brainer... Billet coil spring spacer...
Rear...has 1.5" spacer block from factory.
Need to add 1.5 more... To maintain rake front to rear...for towing and hauling.
3"block is easy.
But...
Know anyone who's done this to 2009 or newer f150?
What brand components are best.. Function and value?
Any problems with the plan?
And... Anyone know of a progressive.. Add a leaf design that would lift, carry more weight...
Without ruining the empty load ride/handling and comfort?

If you stay with factory equipment its going to ride better,3" blocks works great on this much lift as for carry a load air bags do a good job for this when towing or hauling.
