Hey John, I drew up a little diagram showing the spacing for the mounting holes in the Dometic RV Furnace Access Door #DMC57RR flange and access door. For mounting the flange to the RV walls you'll go with the holes spaced further out at…
I would be happy to help you choose the correct replacement leaf springs for your 2018 Open Range 2804RK but the axle tags do not have leaf spring information on them. You will need to measure your current springs from center of spring eye to center…
The torque requirements for leaf spring u-bolts depend on the diameter of the u-bolts that are being used. If the gross weight of your tandem axle trailer is 7,000 lbs, then you likely have two 3,500 lb axles. Typically 1/2 inch diameter u-bolts are…
You most certainly can put a stronger leaf spring on your trailer. Just keep in mind that it could very well make your trailer ride a little more rigid and won't be as smooth depending on what you upgrade to. We do have a variety of leaf springs…
Dexter doesn't actually make a 4k rated axle, but they do make a 4.4k axle which has a diameter of 3 inches. The next smaller axle is a 3,500 lb axle which has a 2-3/8 inch outer diameter.
Good question, and what happens is that leaf springs elongate over time, and since you mentioned you got measurements of 25-1/2 inches from center eye to center eye and 26 inches under partial load, the best option for leaf springs really is the…
Most trailer leaf springs will have a bushing in the eyes of the spring. It is interesting that the install video we have for the wet bolt part #126B2 that you referenced does not have a bushing involved at all. In reality all that really matters is…
As long as the weight capacity is inline with your trailer/axle rating and the measurements match your current springs, the number of leaves in a spring pack does not matter. The difference between a 3 and 4 leaf spring pack within the same weight…
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…
For all of our springs we list the unloaded length measured center eye to center eye straight across. Leaf springs can extend up to 1" when flexed. If you are looking to replace old leaf springs, you will want to jack up the trailer so that the…
It really just depends on what you are looking to get out of the bushings. Bronze bushings, like part #K71-291-00, will last longer but are more noisy and it is recommended to use wet bolts like part #126B2 to keep them lubricated. Nylon bushings,…
