    plate your beams and radius arms heavily
    eliminate all ball joints and bushings with uni-balls
    After market or fullsize hubs and brakes
    plate your cross memmber before it starts cracking
    plate your coil buckets
    and the biggest thing!!! think Lite Lite Lite!!!

    tie rods are a major weak point.. make new one's from chromoly And use heims on the ends instead of balljoints, also the ranger 28 spline axles are pretty weak explorer rear diff has 31 spline, much stronger

    We're slowly converting our truck from Stock Mini to 7s. We went out testing last weekend and pushed REALLY hard to test some new parts. Broke the cross shaft in the rear end and it fragged the carrier and the gears. We were using the same rearend that the truck came with and, since it was an FX4 L2, we assumed that it had the 31 spline axles. We'd never broken a shaft and didn't really pay that much attention.

    Long story short, we raced about 2000 miles on a 28 spline ranger axle and never broke a shaft in a 5200lb truck.

    Yes, the new axle is a 31 spline, but I was amazed at how much abuse the 28 spline axle took. The trick, as it turns out, is to truss it really well because the housing IS very weak. Also, make sure your gearing is right and you have about 150% of the cooling you think you need. Spend every last penny you have on shocks and have someone that knows what they are doing set them up for you.

    Yes it is. Most of the 4x stuff is actually stronger and the 4x will pull you through the silt really well. Look at Darren Yorks truck, now the PBR truck thats for sale on RDC.

    Rob Mac raced a 4x4 a-arm ranger for years and was pretty successful too.

    Kind of ironic, isn't it? All this plating AND trying to think light? What material are you referring to for the plating? I would be guessing 10 GA cold rolled 1018?
