Fits like a glove.

Had to replace a damaged spring seat. This one fit my 3.5" axle tube exactly and my springs dropped right in.

Perfect for my 8K axle.

I needed a spring seat for my 8,000lb axle and this was a perfect fit. The weld-on design made installation easy and secure. The quality is excellent.

One was slightly warped.

One of the spring seats had a minor warp, but it was still functional and welded on fine after some convincing. The other one was perfect.

Solid and well-made.

The raw steel is a good thickness. Welded on with no issues. These feel much more secure than the old ones I was replacing.

Sturdy and simple.

Good, heavy-duty spring seats. Nothing fancy, they just do the job right. Exactly what you want.
