Heavier than expected. Little early to review until I can install and try it out. Looks exactly what I want. Instructions are a bit condensed and will need further examination to understand.
First, let me say the service I received from etrailer was superb. Now that’s out of the way, the very mixed reviews on the JT’s Strong Arm product is very deserved. I have not gotten to use them yet so I am just commenting on the installation.
I’m not the best mechanic in the world but was trained by USAF as an auto mechanic at the end of the Vietnam conflict so I do have some experience. The directions are nearly useless, frankly. I would rather have had them tell me in general terms how they operate and let me figure it out on my own. Once I put away the instruction sheet they were easy to install.
One tip I’m glad I read in reviews, and not mentioned in the instructions, watch where your electrical and gas lines route along the inside (sometimes hidden) part of I-beams and C-channel. Yes, you should always do that when drilling, but when frustration from reading bad directions gets in the mix it’s even more important. That one tip saved me time, money and possibly injury.
The “self-tapping” bolts did not self-tap, either. I tried running them in by hand and with a cordless 1/4” impact. Both times the self-tapping just stripped threads off which meant I had to go buy more ny-lock nuts. I got a good education on how scissor jacks are made, too. Not from the instructions, but from a mistake I made putting in the swing bolts and letting the center piece of the jack “gearbox” come loose. That could come in handy in the future.
I also read that someone ruined a scissor jack trying to move the jack up or down with the Strong Arm T-handle tightened. I am capable of learning from other’s mistakes so I am putting 3/4” silicone vacuum hose caps over my jack so I can’t run them up or down without first checking the T-handle. That should be included in the kit IMHO. The T-handle should also have a tether since it does not have any kind of thread-lock to keep them from working loose as you drive down the road if you don’t re-tighten them in the stored/up position.
I will update my review when I have a chance to use them.
