Seems to be good thus far. That was what I wrote after I got the trailer put together. Now I have to say this is performing way above what I expected. It’s a 3500 pound axle and a assume that means trailer and load weight. I just hauled a bunk of 7/16 OSB, 69 sheets weighing 50 pounds a sheet. 3450 pounds and it performed excellently. The guys at Lowe’s we’re very surprised it did it. Oh, I pulled it 35 miles. Very good product. ### ⭐⭐⭐⭐⭐ I couldn't be happier with how my trailer performs *by S***M on August 10, 2020* I tried to navigate the morass of trailer parts. Finally I found this bundle that included everything I needed. I was confident that all would fit and belong together. Indeed the instructions I received were clear. The measurements were clear. Everything was high quality. Installation went smoothly. After installation the trailer is a delight to pull. The axle and hubs are so smooth. The leaf springs perform well under heavy loads. This is a huge improvement to my trailer's performance. ### ⭐⭐⭐⭐⭐ Excellent! *by D***S on March 27, 2021* Showed up fast, was exactly as described.Nice folks to deal with, too. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/46301151-3-500-lb-idler-trailer-axle-kit-full-suspension-running](https://www.desertcart.us/products/46301151-3-500-lb-idler-trailer-axle-kit-full-suspension-running) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-09-03*
