Question

Question:

Need to replace leaf springs on my 2009 Jayco Eagle Super Lite fifth wheel RV, model 29.5 RKS, Dual axles rated at 5.3K. Also want to move from underslung to over the axle. What springs and over/under conversion kit do you recommend?

Hey Robert, so for 5,300 lb axle leaf springs you would want the part # e76SR which is a 24-7/8 inch long spring.

Since your axle diameter would be 3 inches the correct over under kit would be the part # K71-385-00 which comes with everything to move the axle.

The eye-to-eye measurement of the current springs is 26”. Does that change your recommendation?

@SloughR If I were you I would go with the 6k rated part # e94SR which is the length you have otherwise you'd have to move the hangers.

The 6-Leaf Double-Eye Spring for 5,300-lb Trailer Axles #e76SR will work as a replacement if they're the same or close to the same length you currently have. The capacity difference is so small it won't make a difference. Go ahead and measure…

To correctly measure a leaf spring, you'll want to jack the trailer up on jack stands so the axle is hanging freely, then measure directly across from the center of one spring eye to the other, as shown in the provided diagram. The height of the…

Answer 9

I contacted MORryde and this does happen from time to time as the weight of the trailer can spread out the axles due to downward pressure on the springs/suspension. Odds are the 35" wheel base #MR27ZR will be the correct one for you, but they…

Answer 12

Well shackle length is mainly based on the height difference between the front and rear hangers. The rear hanger normally doesn't hang as low as the front so that the shackle can offset the difference and add the ability to move. What is the…
