Angled tube shape, designed for vehicles that have staggered frame positioning. Most trucks do not have a straight frame, so these brackets can be mounted with little or no modification. Shock hoop can be tilted or angled to position on the frame in relation to the lower shock mount. Two pairs of curved shock tabs are included, but not welded for that custom mount. If dual shocks are desired, we have additional shock tabs available. Made of 1.5" DOM and .120 wall tube, this is a very sturdy, strong upper shock mount that can take abuse.
