For your 2019 Keystone Sprinter Limited Fifth Wheel trailer that has a Lippert 1116 pin box installed on it currently the best cushioned upgrade option we have is the Trailair part # LC155943 which uses an air bag and shock to cushion bouncing and jarring. This option will do the best to cushion the ride quality and also has more capacity than you'd need as it's rated for 21,000 lbs trailer weight. view full answer...
The correct SolidStep Manual Fold-Down Steps for your 2018 Keystone Sprinter Limited are going to be part # LC791575. According to Lippert, you simply need to measure your doorway and then round up to the nearest even number which in your case is 30. The above is designed for a threshold from 35" - 44" so I can confirm this is correct for you. view full answer...
Since we know your 2019 Keystone Sprinter 3531 5th wheel has 7k axles like what the Dexter hub part # 42866UC3-EZ fits we know that the correct Bearing Buddy is the part # BB2717 that you referenced. Or if you wanted the stainless steel version that won't corrode you'd want the part # BB2717SS.
It's pretty easy to over-fill hubs with grease using Bearing Buddies though so be careful not to put so much grease in the hub that it blows out the seal on the backside of the hub. view full answer...
