Can I Upgrade My 3,500 lb Leaf Springs To 5,000 lb Springs If The Measurements Match?

Question

Question:

I am looking to replace my leaf springs on my trailer. It is a single axle rated at 3500 lbs. Is there anything wrong with using the 5000lbs springs if the measurements all match? Just looking to go a bit heavier duty than what was on there from the factory.

Hey Kevin thanks for your question. There is not much downside to going with the 5,000 lb springs instead of the 3,500 lb. A higher rated spring may make the ride a bit more "chunky" at times, since the spring would not flex as easily. Other than that, the springs can definitely be upgraded as long as the eye-to-eye length matches. So if the current springs measure 25-1/4" long eye-to-eye when not under a load, the 4-Leaf Spring # e44SR will be the one.

Keep in mind though, that upgrading the springs does not increase the weight capacity of the trailer. The weight capacity will still be limited to whatever the lowest rated component of the system is, whether it be the axle, hubs, brakes or trailer frame, all of which are likely rated for a max of 3,500 lbs.

If you are wanting to go to higher capacity leaf springs I would advise against it. The problem is that since the trailer axle is rated for 3,500 pounds you won't gain any additional capacity by switching to higher capacity springs. What it will…

Your 2017 Grand Design Imagine 2150RB does in fact have a 35" wheelbase so the correct MORryde CRE3000 is the #MR27ZR. Unfortunately, Grand Design doesn't list the shackle length but I believe what you have is 2-1/4". This measurement…

Thank you for providing that information. Leaf springs like the ones you have now typically match the axle capacity on your trailer. Although adding leaf springs with a slightly higher capacity won't hurt, it also is not necessary. Based on the…

Hey Ken, since the Lippert 4,400 lb trailer axles are 3 inch in diameter the Roadmaster Comfort Ride system part #RM-2460-2560 is correct as that is what diameter axle it is designed to fit. The springs will be a little uprated for more than…

Hi Jason; do you know the capacity of your Dexter axle? More arch for height isn't really a thing, and I wouldn't get longer shackles since that would throw off suspension geometry and be uneven since the front hanger stays the same. It is…

Grand Design lists an 86-1/2" 3,500 lb axle for your Imagine 2150RB. The next size up would be a 5,200 lb axle like the #e45GR. This has the same 86-1/2" hub face measurement but the spring seat is different. You will need to cut off the…

Yes, the 25-1/4" Long 3-Leaf Double-Eye Spring for 4,000-lb Trailer Axles item #e57SR, will indeed work to replace your older springs. You're going to be an inch shorter on your suspension travel using two of these so it will make your ride…
