I'm running Fox Factory 2.5s with ext reservoirs, no limit straps.
With 10-12" shocks, most stock replacement springs droop out prior to the shock topping, so there's only the axle weight on the shock. The rebound valving meant to deal with the spring AND the weight of the axle should prevent any harsh topping (i.e. only blown shocks smash into the top out stop with no preload), and the internal construction of a Fox Factory is more than capable of holding up an axle.

Doesn't mean they're useless, but on a Jeep, I don't think they're entirely necessary. Chances are you'll eat the seals and need a rebuild before you kill anything in the shock from topping out anyway.
On my buggy, they're absolutely necessary since my CVs will bind before the shock tops out.
