Feels heavy-duty and strong

I was a little worried about ordering online, but this spring is serious business. It's thick and heavy, and you can tell it's made to last. Glad I went with this one.

Exactly what I needed, no issues

Ordered two of these to replace some worn-out springs. They were a perfect match and bolted right up. The trailer feels much more secure now.

Solid and well-made

I'm very impressed with the quality. The spring leaves are thick, and the overall construction feels robust. It was a perfect fit for my 12K axle replacement project.

Minor rust on one leaf, but still solid

There was a tiny bit of surface rust on one of the leaves, probably from storage. It's purely cosmetic and doesn't affect performance. The spring itself is very strong.

Good product, minor shipping delay

The product is exactly what I needed, and the quality is top-notch. However, shipping took a couple of extra days than expected. The spring itself is perfect.
