Good build quality springs especially for the money! Fit my 2020 Tracker 190 TX trailer perfect! Quick easy install, and the springs function well

Order arrived today, not yet installed. Packaged well. Appears to be made well. Fitment appears correct. Doesn’t look like I’ll have any issue once I install.

(2024-06-03):The two leaf springs are completely asymmetrical, and the center is not aligned. The axle will be crooked when installed in this way. The paint job is also very poor.I submitted a replacement request, and I will update you when I have more information.----------------------------------------Update #1 (2024-06-11):----------------------------------------Seller sent me a replacement for the previous quality issue, I really appreciate that.However, I don't think the manufacturer's claim of 5000 lbs weight capacity for the leaf springs is accurate. The axle of my travel trailer is rated for 4400 lbs.After replacing one side, I noticed that the travel trailer sank much more than before replacing the old ones.I measured and found that the gap between the wheel and wheelhouse on the newly replaced side is only 2 inches, while the gap on the old side is 3 inches.On the side where the leaf spring was replaced, the shackle was pushed back and tilted a lot.See the comparison of the new and old 4 leaf springs.The metal of all the leaves in this product is relatively thin.And the bottom three leaves are much shorter than my old ones.The bottom leaf is especially short, less than 7 inches long. My old one is 11 inches long.The manufacturer claims a weight capacity of 5000 lbs, which is weaker than the 4400 lbs one, and the manufacturer exaggerates.I have no confidence in this product.The worst thing is that I have a trip the day after tomorrow. I have to waste time to put the old one back on.After my trip, I will try to contact the seller to see what solutions they have for this problem. I will then update my review.

I used these to replace the old springs o my travel trailer. It also raised the weight capacity a little.

Although the ones I initially purchased were not correct for my application, these are well built Springs that are assembled correctly. Far exceed some of the others I have purchased in the last several years from a quality control perspective. Would definitely recommend

No complaints on the product...huge complaint on packaging... box was destroyed on delivery and hardware bag inside was split open...was missing 2 of the nuts for the assembly....very hard to find lock nuts at the local hardware store that were the correct size...
