Feature Breakdown: 2-Leaf Slipper Spring w/ Flat End for 1,800-lb Trailer Axles Video

Hey Tim, I believe the part #e29SR would be your best option and is only off by .25 of an inch in overall length. It is a 2 leaf slipper spring with a flat end like you want and for a 1,800 lb trailer axle. What is the axle capacity of your boat…

Looks like you have slipper springs on your 2001 Coleman Utah pop up. We have replacement slipper springs available like the #e29SR which is 30 inches long and for 1,800 lb axles or the #SP-179275 which is 24-5/8 inches long and for 2,000 lb axles.…

You can usually find the axle capacity on the tongue of the trailer where the VIN number is located. If that tag is missing, there is usually a tag on the axle that lists the capacity. If neither of these sources is available, there are guidelines…

Yes and no, a leaf spring with a lower capacity will provide a better quality ride than a leaf spring with a higher capacity but you will not want to make that part the lowest rated suspension component. Typically, we recommend choosing a leaf spring…

A similar leaf spring that we have is the etrailer 2-Leaf Slipper Spring #e29SR which is 30" long and rated for a 1,800 lb axle. The 30" is measured from the center of the eye to the end of the leaf spring (see attached picture). The spring…

Over time leaf springs will flatten making them a bit longer than their than their original length. You mentioned that the springs on your 77 boat trailer measure 31-1/2 inches so the 3-Leaf Slipper Spring, #SP-039275, measuring 30-1/4 inches would…

Hey Jarrod, thanks for reaching out! I believe what you're looking for is the 30" Long 3-Leaf Slipper Spring w/ Flat End for 2,900-lb Trailer Axles #e49SR, although this may be a bit longer than what you currently have. If you take the…

Hey Jon, none of our trailer wheel and tire combos are balanced as trailer wheels don't generally get balanced. With that said we do have balance beads with the part #CA66VR if you wanted to balance them yourself easily. Have you noticed wheel…

The number of leaves on a leaf spring does not dictate strength or capacity, so as you said, a 3000lb rated leaf spring (6,000lb axle capacity) can have various numbers of leaves since it is up to how the manufacture designed it. I wouldn't look…

Thanks for the picture! There is going to be a noticeable benefit to having larger tires on dirt roads that are poorly maintained. The larger tires will give you a wider footprint by almost 30% which translates to more stability and grip. The Kenda…

You will want to choose the diameter size of U-Bolts you need by the axle type (round, square) and the axle diameter. The Redline 2 Inch Square Trailer U-Bolt, part #SP01-160, you have referenced is for a 2 inch square axle. It is a 9/16 inch…
