Most Popular Rack Lock for GMC Sierra

I bought this bike rack because I didn't want to have to remove my bed cover every time I wanted to take our bikes on a trip. This rack works perfect because I can roll up my cover and this thing just clamps across the bed. Taking the front tire on and off is kind of time consuming but when I travel with my brother who has a hitch mount rack, it takes him just as long to unload his bike as it takes me to unload. The wheel mounts tighten easily and the bikes appear secure during long drives, so I don't worry about them coming loose. Of course, you'll want to wrap a bike chain around the bike and rack if you plan to leave them out to make sure no one can steal the bike (although it would be missing a wheel)

It worked well, but not without doing some "tweaking". When set down on the bed rails the locking pin would not line up with the hole in the bar so it took some filing on the hole to get it to work. Also the axle mounts would not set flat on the mounting pads so that also took some work with a file to get them to mount flat. Once I got all of that done it works fine.

the T-Bolts and Allen nuts are really prone to corrosion. Make sure you unscrew them 2-3 times a year to apply anti-seize and corrosion inhibitor on the threads. Have 3 of these racks and all T-bolts sheared off when I tried to remove them after 1.5 year. Other than that, its a really good bike rack for the price, will buy a 4th one

This is an outstanding rail. And is the second one that I have bought. For a matched set. They were great on my BMW roof racks. Outstanding product as always. Thank you
