Everyone's mentioned a lot of great components.
One important thing to keep in mind is proper use and selection of the gear you have or purchase. The offroad industry lacks any form of standards (or verifications) compared to similar industires - hoisting/rigging (vertical lifts). The hoisting industry has an entire body dedicated to the safe practices and governance in lifting objects along with equipment standards. In the offroad industry for recovery equipment you'll often see mfgs making all sorts of claims about their product quality and load ratings based on no established standards (pretty nice for the mfgs isn't it). Understanding the weak links is essential to safe recovery operations.
The reason I bring this up is folks often have little understanding of the true loads involved in a vehicle recovery which often results in improper selection of equipment (with little to no saftey margin), improper use of gear, or simply unsafe work practices.
For example a 12,000lb winch is a great thing, but few folks consider the line rating or how the line is terminated. Let say it has a great 1/2" wire rope with a break strenght around ~17klb, its off little use if that wire rope terminates in an underated hook or has an improperly done end termination. Unfortunatley, I'm guessing only a few folks on this forum even have an understanding of what is a proper end termination vs. improper (and quite a few products have improper). The mfgs of recovery equipment do a poor job of communicating information like this and with no standards there is a significant disregard for safety margins and best practices throughout the community.
Just to give you a high level example of the types of loads you could see when recovering a vehicle. An FJ with its frame caught up on rocks on a 30 degree uphill slope would take about around ~19,000lbs of force to recover the vehicle (refer to hoisting industry standards and army's guide to recovery for calculations). Normally folks carry a 8-9lkb winch and in the best cases a 12klb winch - needless to say you'll need more than the winch alone to enable recovery with a decent safety margin (foreign topic in the offroad industry).
