Bought these to mount under a 20 foot tandem trailer that was home built out of some very heavy metal!!! Trailer empty weight now cut down to 12 foot and a single axle under it is 1,060#. So it's still a heavy trailer. I have max loaded it with a pallet of quickcrete 80# bags. 42 bags per pallet. So 2,360 weight of cement,+ 1,060 trailer empty weight, they are excellent springs well made and with new shackles, u-bolts, and a hanger kit. They were a breeze to install. Actually did this job by myself. I can recommend this product to anyone who wants to not hear the trailer behind them rattling as you go down the road. I wouldn't recommend that you load your own trailer as I have that heavy. Probably get a ticket for being over axle and not rated to pull with 1/2 ton truck. But it's only a 12 mile drive from the Lowe's to my home.

Replaced all 4 new springs (rated at1750 lbs) on two 3500 lb axles on my travel trailer . The trailer axles are labeled for 3500 lbs each. (Total weight capacity of both axles 1750 X 4 = 7000 lbs) The Springs were sagging after the first trip, which was about 3500 miles. Took the trailer to CAT Scales, just to confirm that the trailer wasn't overweight. The (loaded) Weight on both rear axles together is 6250 lbs. See the pictures, springs are flattened out, and bending upwards. Tires are rubbing inside wheel wells. These springs should be able to handle the weight, but did not. .
