This front bulkhead gusset kit from HCR is what you need to strengthen the front end of your X3. The Maverick X3 has a great chassis, but there are weaknesses that should be addressed. Many suspension components are single shear and do not have the desired support on each end of the fastener. This gusset kit turns the A Arms mounts into a double shear setup! Made of 1/8" 4130 chromoly!
