Rear shock mounts are one of the lowest hanging items in the rear of your van. Our Baja Sur brackets are designed to wrap and reinforce the thin factory lower shock mount with laser cut and formed 3/16" steel. This adds ridigity and security, as we've even seen reports of careless tire shops bending these brackets by jacking from them. For further peace of mind, we also upgrade the failure prone rear lower bump stop mount on the axle, which has a tendency to snap off on heavy vans that get used off road.
