Correct RoadMaster Slipper Spring and Shock Kit for a 2021 Jayco Jay Flight 29RKS w/ 3 Axles

Question:

Which Road Master slipper spring and shock kit is best for a 2021 Jayco Jay Flight 29rks. The Dexter axlesfoot circumference is 9.5, the diameter is 3, and the weight rating is 5,145lbs. The circumference and diameter align with the Item # RM-2460-2570 kit, but the weight rating for the axles is 55lbs. below the 5,200 minimum range listed. I believe the up to 5,000lb. kit is for the smaller axle diameter 2 3/8. Is this correct? What is the main determinate for kit ion? Do I go with the Item#RM-2460-2570 since the diameter and circumference are appropriate and the weight capacity is within a close enoughinch margin?

I would be happy to help you. The Roadmaster Comfort Ride Leaf Spring Suspension Kit w/ Shock Absorbers item # RM-2460-2570 you referenced fits only 3" diameter round tandem axle trailers. These axles are typically between 5,200 lbs and 7,000 lbs axles. The 55 lbs difference of weight will not impact the effectiveness of this system. Fitment is determined by axle diameter.

For your 2021 Jayco Jay Flight 29RKS w/ 3" Axles you will want the Roadmaster Comfort Ride Leaf Spring Suspension Kit w/ Shock Absorbers item # RM-2460-2570. This system isolates each axle and uses both slipper springs and shock absorbers to give you a smooth ride. It includes nitrogen-charged shock absorbers that help to eliminate trailer bouncing, chucking, and porpoising.

I have linked an installation video below so you can see the steps involved with adding this kit to your Jayco Jay Flight 29RKS trailer.
