Trailer Suspension Upgrade For 7k Axles & 34 Inch Axle Spacing

Question

Question:

I am looking for a Dexter EZ flex suspension kit for my 2011 Landmark Grand canyon. It has 7000 lb axles and a 34 inch space between axles center to center. The old hanger is 6.25 inch with 2.75 inch.

There are some options for suspension upgrades, though an E-Z Flex or other equalizer upgrade isn't available with the axle spacing or similar equalizer measurements. So the best option I can offer for an improved ride are shock absorbers:

- Roadmaster Comfort Ride Shock Absorbers for Tandem Axle Trailers - 5,200-lb to 7,000-lb Axle # RM-2460

The # RM-2460 will give you a much improved ride, even more than the E-Z Flex. because it greatly reduces the overall movement of your trailer's suspension, giving you a smoother, more controlled towing experience.

Hey Patrick, so for your leaf spring upgrade I am going to need to know a couple of things before I can get you over to the right part. Specifically, the length from eye to eye, the spring width, leaf thickness, and the number of leaves. From here I…
