Some time back, I had to haul my daughters Blazer home so we could put a fuel pump in it. I got it loaded fine, but we bent my cheapy ramps badly when unloading. So today, I went about beefing both sets up a bit. These are HF 6' ramps. Rated at 1000 lbs. Allis weighs in at close to 1500. Thought I had better do something now.
The set I just bought (and were still straight), I bolted in a section of composite deck board. That should help them out.
The bent up ones, I ripped some 2X boards to fit and bolted them in. I trimmed all protruding threads back to the nuts.
Should make these last a bit longer!
