Rdlogics now list the 120mm swift pro big bore shocks as replacement upgrades for Wolverine. Part number starts with UG for swift upgrades
Below is the link to CPV racing who are starting to make alloy parts for Raptor/ Wolverine. Personaly , the only alloy I would put on is steering knuckles, as the plastic are a bit random for the bearing hole, and tye rod ends. Wolverine/Raptor doesnt need the extra strength of alloy for areas like diffs and bulkheads as it is a pretty strong truck to begin with. Plus plastic is cheap when you break it
