  • Works great
Size: 37" - 61"
Replaced a non USA made spindle jack thought was holding only the stairs and landing but was also supporting part of the house. The old one was rusting away/ fell apart when removed and was under sized from a big box store. This support is a Cadillac, sturdy and easy to adjust with the screw. Well worth the money spent. ... show more

  • Highly recommend

These jack stands are the bomb! Easy to use. Th telescopic feature allows you to lift to any height. I used these to level out my 42 ft RV. It was soo easy. I did buy a hydraulic jack lift to lift the RV and then placed the jack’s appropriately.

  • Poor performance appeared used
Size: 13" - 17"
Product appeared used and the quality of the parts did not seem substantial for price paid also cost to ship. I retuned both items purchased and my refund was severely delayed which was not acceptable to me. I would not buy this product again.
