I asked ARB about a diff drop or a pan hard bar. They said that neither were needed with their kit. Since they did the suspension for the trailhunter, they probably know the platform fairly well.
The Road So Far:
Full set of Trailhunter skid plates
OEM TRD tow hooks front and rear
Westcott Design ditch light brackets
Morimoto 4Banger amber ditch lights
I did a full front end PPF. Couldn't quite afford the whole thing this time. But then did a ceramic coating at a local shop. Saved a ton of money there.
I dont have either one of these as I'm just going to upgrade the whole suspension. But if I had to choose between the two, I would choose the westcott. From my understanding, the ready lift is a spacer lift and I'm not a big fan. Preload collar offers the same dynamics as an offroad...
Now that sounds perfect. The coilovers fro arb will handle up to 200 lbs without sagging, but their rear isn't designed for additional weight. Sounds like your springs and their kit might be a perfect marriage.
Sorry if this is off topic but I noticed you said your springs allow increased load carry. I have been considering the new ARB kit, but the rear springs in the kit would not allow for my chosen steel bumper and swing outs. How much weight will your rear springs allow?
