I went through this a few years ago looking for a replacement for a mid '90s 3 ton Craftsman I have. Still haven't picked one up yet as my smaller 1 ton units have been holding up okay. Glad to hear the less expensive Daytonas are doing okay for some of you.

In all honesty, the failure point of these jacks are in the ram assembly. Maybe we should ask the question around what jacks have replaceable ram assemblies in them instead of which ones hold up the longest. Funny thing is, trying to look this up, I find plenty of places that sell parts and rebuild kits but I'm not having much success in locating a complete ram assembly. Obviously jacks are built with these as a component, but finding someone who list them as a replacement part seems impossible. Maybe I'm not searching with the best terms.

In that vein, I notice Summit sells a Sunnex replacement ram for $100. https://www.summitracing.com/parts/...GmtKq7QIVCuWzCh1-DAomEAQYASABEgL3JvD_BwE

Looking up the compatible jack I find this: https://www.summitracing.com/parts/sxt-66037 for $255 and a low profile for $320 (on sale for $288): https://www.summitracing.com/parts/sxt-66035sj?rrec=true

But if you can replace the whole jack for $120 with a Harbor Freight unit, is it worth the hassle?
