A loose or misaligned axle can throw off your trailer’s stability. This spring seat welds onto a round, 1-3/4" diameter axle (typical 2,000-lb axle) to keep everything square and supported. Its cutout lines up with the raised knob on a 1-3/4" wide leaf spring, locking the parts together so the spring won’t twist or shift under load. Once welded, it gives your suspension a solid mount point that holds alignment mile after mile.
Getting the axle and springs to fit just right is key to proper suspension movement. This seat is made specifically for 1-3/4" wide leaf springs, giving you the correct spacing and alignment without guesswork. Two seats are required per axle to complete the setup, ensuring even support on both sides.
Whether you’re fixing worn components or setting up a new suspension layout, this steel seat makes it easy to get the job done. It matches the axle material for clean welding and strong adhesion. You can position it wherever needed to adjust ride height or correct spring spacing, then weld it in place for a permanent, reliable hold.
If you’re doing an axle flip for more ground clearance, this spring seat is exactly what you need. Weld a pair of them to the opposite side of the axle to relocate the springs on top, and combine with a U-bolt kit like part #APUBR-10 for a full over-under setup. It’s a straightforward way to lift the trailer and gain the clearance you need for uneven ground or driveway transitions.

Today we're going to be taking a look at a spring seat for typical 2,000 pound, round trailer axles, with a 1-3/4 inch diameter. The spring seat is a necessary component of your trailer's suspension system. When mounted with a 1-3/4 inch wide leaf spring, it adds extra support and provides proper positioning for the axle. This unit's made from a durable steel construction. It welds on to a round 1-3/4 inch diameter axle, which is a typical 2,000 axle. It sits on top of a 1-3/4 inch wide spring. The cut out on the flat side of the seat surrounds the raised knob on the leaf spring to prevent turning or shifting.
It's going to provide extra support and secure positioning for the trailer axle. Please note that two spring seats are required for each axle. A few measurements to go over with you real quick. Start with the overall length, measuring edge to edge. It's going to measure about 2-1/4 of an inch long. Overall width, measures about 1-7/8 of an inch.
The height, is just shy of 1 inch, about 15/16 of an inch tall. Then this opening, right here, the rounded point, at the widest spot, that's going to give us an opening measurement of really close to an 1-1/2, maybe 1-7/16 of an inch, right in that area. That's going to do it for today's look at the spring seat for typical 2,000 pound, round trailer axles, with a 1-3/4 inch diameter.

I ordered a couple of the 1- 3/4 U bolts from eTrailer as well. Yes, weld up the perches opposite the old ones but be sure to take some time to make sure theyre aligned both vertically and horizontally. I used a level to compare the top plane of the new perches with the bottom plane of the old ones with the axle upside down and clamped it in place before welding.

Hey John, Im about to do the same thing to my 89 Coleman pop up. What u bolts did you use and what other items did you need? Just weld these opposite of the old ones and replace springs with u bolt?
