It was much simpler to install the Jounce Shocks on the rear of our donor truck. First, a template was used to mark four 12mm holes that needed to be drilled in the framerails. Next, a small portion of exhaust heat shield had to be removed for clearance. (See green lines.) Next, a bracket was installed around the lower shock-mounting points and axlehousing. This bracket provided a landing pad for the Jounce Shock cylinder while at the same time protecting the OEM shock mounts. This setup is slick because it can't be installed incorrectly, and it provides much-needed protection to the lower shock mounts.
