Yes, but limited to symmetrical arms. I think your design that drops into the lift pad holes is trick.

My point, yet the pic looks like it's installed on a asymmetrical

Sym lifts can have arms w/ different lengths. Asym lifts either cant the columns at an angle and use straight arms, or have square columns but physically asym arms. Asym lifts allow you to point BOTH arms in the same direction when driving though.

Heres a pic of my arms. Notice how the left one will point to the right and fit flush against the column due to the L where it swivels.

Edit, what they prob really mean is that it will only work w/ straight arm lifts. Since they only sell the bent arm asym versions, it will only work on their sym lifts.

I think Kurt's design is the best of the bunch, I just think he likes that someone else is making one so he doesn't have to have all kinds of 2-post dorkis banging down how door to build them one...right?

If he endorses the LMA design, I'm all for it. I have a feeling I'm leaning toward a 2-post with this type of adapter...now I just have to choose the lift I want (one that is safe, not sure if the Direct Lift HR8000 is safe enough to buy...I know it's a Rotary Lift brand, but the BendPak XPR-9F seems better, and $1100 more money, even though they are both non ALI certified).

Beat all you want you can't pay me enough to take the risk of making lift adaptors.
Someone will figure out how to use it wrong and kill an entire sack of babys or something. I might help someone make their own set so long as they promise to never ever use them for lifting anything.


I liked the simple nature of the Greg Smith method, both in use and how it is made. Ramp and device in one and no tools to convert from 2 to 4 and back. Over the arm so little chance of Joe Dim Dumbazz installing it wrong and looks easy to ajust to the car's track. As noted it will not work with asym lifts. Another reason for me to not like them too much. should have seen the fight I had getting a 2500HD on one. Lift was rated to 10K but there was not enogh arm to get to the lift points on the truck. Cheap even steven 2 post was 2 min and up.

When did Bend-pac go non ALI on the 2 posts? Mine has the gold sticker.

Good point about the home-made lift adapters.

I think the new 9000lb 2-post lift is pending approval. They don't make an open-top 10,000 lb lift like you have any more.

It's good to hear this info and approvals on the 2-post lifts. I'm still debating the 2 or 4 though...I'll go out and do some tape measuring this weekend and hopefully come to a decision.

I have a greg smith 2 post w/ asym arms (atlas 9k? overhead). Not sure what super sym arms are. I actually bought an extra pair of short ones to work on the 986/996. They had them in stock (common request they tell me.) New pcars are wide w/ short wheelbase and was really hard to swing the regular one short/one long pair under unless you parked perfectly centered & front/back. Never needed to put the long pair back on (my truck doesn't fit through the garage door.)

Like the first few pics here:

Thanks, I might have to invite myself to visit your setup.

I was looking at

The Atlas 9OHSC has super-symmetric arm configuration
Not clear to me exactly what that means either. Really looking for a Mohawk, but since I havent looked in a couple years I wanted to see what's new to the market.

Mohawk = $$$, but they are cool...even have drive-on adapters for longer/term storage.

That reminds me, I need to get around to getting a bridge jack for my 4-poster....
