I feel I need to dig up this thread and share my experience. I purchased two Worth lifts in 2014 because I was dead-set on buying USA made lifts. One was a "12k" 2 post, the other a 18k 4 post.
Within a year we bent the arm pins of the "12k" 2 post lifting nothing but a 9000# pick up truck (it's all we worked on). At that time I reached out to Worth with phone calls, messages, and emails with pictures. I expressed my displeasure of what happened and I felt that I was sold a 10k lift instead of a 12k lift, as evidence by the photos on THEIR OWN website showing the differences of the lifting carriage and arms between the 10k and 12k lifts. The 12k have a much better design that is common with my Challenger and Forward lifts. My "12k" Worth lift has a totally different design that isn't what's shown on their site, even to this day. It directly matches their 10k lift pictures. Not one single response from them at all on the matter. I finally gave up and we only used that lift for light duty.
Fast forward to today, I have decided to sell the lift and I called Worth to order new pins so that the new buyer doesn't get a "damaged" lift, even though it works fine, you just need to deal with the arms dropping. When asked what model I have, I explained the situation, that I believe I was sent a 10k lift with a 12k tag, but I wanted to email them pics of mine to know for sure so that I could get the correct pins. I emailed them some pics and Steve quickly called with an attitude. I honestly just wanted to buy new pins and I wanted the correct part, that's all I wanted, I wasn't looking for any responsibility from them for the damaged pins. He went off on me on why I have a problem with his "12k" lift, and wouldn't listen to reason whatsoever. His own website has a different picture of the 12k lift; his 9k & 10k lift are of one design, and his 12k and 15k show another design of arm and carriage. He refused to listen, literally called me weird and told me to go somewhere else. He said over and over he didn't know what my problem was. I didn't have a "problem", I was confused by why his "12k" lift failed lifting a 9000# truck, and his own website shows a totally different lift for the 12k option. Proof in my mind that they screwed up and labeled the lift incorrectly. He just refused to hear what I was saying totally.
I HIGHLY recommend that NOBODY deal with these people. Although my 4 post lift has worked flawlessly daily for over 10 years, he refused to listen to my concerns and insulted me on the phone when I tried to explain clearly why I was questioning the lift I had. My goal was simply to supply them with correct information the best that I could so I could get the correct parts, and they flat refused to deal with me.
How's that for customer service?
If anyone is looking to get a 12k two post lift then you'll want to pass on the Worth lift, it's a crappy design that won't hold up. Their 15k lift appears to have proper lift arm construction for the rated weight, but not the 12k. Then you'll have to deal with attitude if you ever actually need anything from them....
