lcwizard said:first a lesson in four link geometry.
draw an imaginary line along your upper and lower rear four links. the forward point they intersect dictates the imaginary point that forward momentum is transfered to the vehicle. all competition rock crawlers and buggies aim for the vicinity of the motor mount. the lower the point the better the vehicle will climb serious obstacles. in a climb your truck already unloads the front end and doesn't need the rear end making the situation worse.
another scenario is approaching vertical ledges, say 3/4 your tire hieght or more.
with steep control arm angles torque reaction forces the ass end of the truck upward as the axle tries to drive under the truck without you.
maybe your wheeling style isn't severe enough the take advantage of the performance gains of a correctly setup four link in which case you are free to compromise. however after years or competing in the rock crawling circles and
involvement in their build up , i can say with confidence that an inproper fou link setup has no advantage over leaf springs and may function worse.
As for the front end the brackets merely allow lift without compromising street handling
Great info. Thanks for the post. I learned some new stuff.
