Peerless 1054005 Self Tightening Passenger Car Traction Chains. New ~ never used. I have the carry case, and the big plastic instruction panel with photos that doubles as a mat to keep you dry in the snow while attaching.
Auto‑Trac can be installed without moving (or jacking up) the vehicle! The patented, ratcheting tightening system automatically tightens the chain while driving. Just connect the inside cable, attach the two outside selftighteners and drive! No additional chain tensioners are necessary or recommended. Auto‑Trac will meet Class “S” clearance requirements on SUVs and pickup trucks, as well as normal passenger cars (matching the capabilities of most of our “Z” cable products). This is possible because of a highly effective, patented tensioning system. Auto‑Trac cross member links are made of manganese alloy steel, allowing them to be shorter, narrower and lighter than conventional cross members. This reduces “fly‑off” during operation and provides more gripping points. The low‑mass “D” cross section of the links also contributes to longer wear because the impact of the cross members on the road surface is reduced and the surface area contacting the road is increased.
Here is the Amazon URL where they are listed at $104 with hundreds of 5-star reviews for these high-quality chains. I will sell for $40. These are some of the highest quality cable chains you can buy for your car. Are you prepared to head over the pass?!
