Hey Bob, congrats on the new 5th wheel trailer. If your Jayco Pinnacle has 3-1/2" diameter 8,000 lbs axles you can use the Roadmaster Comfort Ride Shock Absorbers for Tandem Axle Trailers item # RM-2470. These shock absorbers are nitrogen-charged so they'll help with the road shock along with trailer bouncing and that chucking feeling.
What size are your axles? The plates on these shocks tie into your u-bolts so if you do not have 3-1/2" diameter axles this kit won't work.
