Will SumoSprings Trailer Helper Springs Work With Dexter Heavy Duty Suspension Upgrade Kit

Question

Question:

Hi, Im looking at upgrading the suspension on my 2011 KZ Sportsmen travel trailer. The suspension is original except for recently replacing the double eye leaf springs The Travel trailer has a ton of miles and has been everywhere. The trailer has a 2 3/8 3500lb under spring Dexter Axle. Ive had issues with bottoming out, blow outs damaging the wheel well and Travel Trailer, theres very low clearance. I was thinking of doing the following- Gaining height by installing the- Dexter Trailer Springs Over-Under Conversion Kit Item # K71-384-00 Adding stability and cushioning the ride by adding- SumoSprings Trailer Helper Springs w/ Line Relocation Bracket - Single Axle - 3K to 5K - Overslung Item # TSS-107-40 And possibly adding this upgrade kit. Dexter Heavy Duty Suspension Upgrade Kit for Single Axle Trailers - Double Eye Springs Item # K71-358-00 It looks like I have about 6 1/2 inches of clearance between the leaf spring and frame no load. Is this sufficient space for the SumoSprings once I install the Over-Under conversion kit? Is this compatible with the Ove-Under conversion kit?

Expert Reply:

The SumoSprings Trailer Helper Springs part # TSS-107-40 will be installed unloaded with a greater distance than normal between the leaf springs and frame. The springs will then compress when you lower the trailer on them. Therefore, there doesn't need to be a gap between the frame and leaf springs equal or greater to the height of the springs. There will be no compatibility issues with the Dexter Heavy Duty Suspension Upgrade Kit for Single Axle Trailers part # K71-358-00.
