I have a 2018 pinnalce 37MDQS and standard equipment is the 5 star handling package which includes 7K dexter axles w/self adjust brakes, dexter wet bolt/bronze bushing shackles, morryde pinbox, morryde LRE4100 rubberized suspension and (5) goodyear
"Beast" tires. My unit was built in June 2017, and the booklet shows those items and standard also. Unless Jayco changed items, they should be standard. Hope this helps.
