Fig. 1 shows the Superior Arm deflecting only 4.1mm under load with real world load points.
Fig. 2 shows the Competitor's Arm deflecting 24.91mm under the same load points and loads, almost the same as the width of the Arm itself.
Also of note is the Competitor's Arm deflected to a point that may cause metal fatigue over time, which may lead to total failure.


Cast radius arms are more vulnerable to breaking, leaving your vehicle undrivable and you stranded.

vehicles it is highly recommended to move your suspension in the full range of the
shock absorber compression / rebound travel and also taking into consideration coil bind,
check all areas for clearance issues , if you require more assistance in this talk to one of our sales team for further advice
