You can use leaf springs that are rated higher than the axle without any issues as long as they measure the correct measurement for your trailer. For example the 6-leaf double eye spring for 7,000 lb axles part #e64SR measures 24-7/8" eye…

Yes, our Dexter leaf spring part #DX74XR is the same as the part number 072-079-00. This is a 7-leaf spring for an 8,000 lb trailer axle that is 24-7/8 inches.

We don't carry Dexter leaf springs, but we do offer the 4,500, 26 inch long center eye to center eye equivalent as part #e27SR.

We can definitely help! But I need you to get me the axle capacity on your trailer and the lengths of your current springs (the good ones) so that I can pick you out the best solution. Or you can check out the link I attached to this page that has…

I recommend using the SumoSprings Trailer Helper Springs #SS26MV on your 2021 Grand Design Momentum 395M. These springs are rated for use on axles with a capacity of 5,000-8,000lbs and are mounted below the leaf springs. Your Momentum has three…

For a 7k trailer axle leaf spring solution the best we can offer is the Dexter leaf spring part #DX74XR which is rated for up to an 8k axle and is 24-7/8 inches long. You'd need to measure your current springs to verify if this length would work…

I checked directly with Dexter, and from what I saw they have a measurement - taken from center of spring eye to center of spring eye - of 24.8", which is the same as our 24-7/8" measurement for the 7-Leaf Double-Eye Spring for 8,000-lb…

So both of the leaf springs you mentioned are 25-1/4 inches in length from spring eye to spring eye according to Dexter. The closest option for a 4,000 lb axle spring we have would be the part #e57SR which is for a 4,000 lb axle.

Yes the 4,000-lb leaf spring is compatible with a 3,500-lb axle. There are a couple of important measurements. Spacing from eye to eye on the spring when unloaded with no weight on the axle. Inner eye diameter of the spring roll Spring width from…

We do not recommend moving from 7,000lb #e64SR to 8,000lb #DX74XR leaf springs as this creates a stiffer ride with more bounce. This causes more shock to transfer inside your RV which can cause damage to the trim and electronics. Instead I recommend…

You are indeed right to think this way. When picking out the appropriate leaf springs for your custom built trailer you will want to choose them based on what the actual loaded weight of the trailer will be. Just make sure that the leaf springs have…

In the attached diagram the A measurement is actually the distance from the center of the spring hangers for a single axle trailer. The spring eye to spring eye measurement for your leaf springs will be slightly different. The B measurement that you…
