5" x 5" structural steel posts in combination with computer guided laser cut lock notches allow us to offer a superior, more rigid and incredibly strong alternative to most "c-channel" lifts on the market. Combine this with a 5/8" thick by 12" x 12" base plate and you get a structural post that is as supportive as it is rigid. When working in conjunction with our 2" x 4" crossbeam that wraps all the way around the post to offer not only front to back but also side to side stability you get a lift that comfortably allows you to raise and lower your vehicle each and every time safety and security. With thicker than industry average sidewalls our crossbeams do not need additional reinforcement. Simply put, we engineer our crossbeams and uprights to a higher level than the average lift by using higher grade stock material when producing our lifts. To put this in perspective, Wildfire Lifts uses 6mm (.236") thick side walls on our upright posts and crossbeams while other "similar looking" lifts only utilize 5mm upright posts and crossbeams (.196") this means that Wildfire Lifts offers upright posts and crossbeams that are ~20% thicker and more robust than our "look alike competitors" - when we say no one builds lifts that are as stable or as robust as we do, we mean it! You benefit from a more secure and more robust lift! (don't let those guys try and round their number to a 1/4" when you speak with them, that is factually inaccurate). Also note that all Wildfire Lifts posts and crossbeams are last cut for clean uniform lines, have you looked at the photos from our competitors who use hand laser cuters and it looks as such?!
