If you already own the MAXXHAUL 50709 detachable car ramps and need extra length, this middle section extension is exactly what you're looking for! Each extension adds 26.2 inches of length to your existing ramps, which can make all the difference when working with lowered vehicles or trucks with longer wheelbases. The industrial-grade PP material is seriously sturdy - it maintains the same 6,500 pound weight capacity (3,250 pounds per ramp) as the original set. I added two of these to my ramps to work on my lowered sports car, and now I have plenty of clearance without scraping the front bumper. The built-in handle on the side makes carrying and positioning the extensions much easier than you'd expect. The interlocking design with the original ramp sections is secure and stable - no wobbling or shifting when driving up. The poly black finish matches the original ramps perfectly, so your extended set looks completely uniform. Just remember to always place the front section on hard, smooth, level surfaces - don't use these on dirt, grass, or uneven ground. If you frequently work on different vehicles or need that extra reach for clearance issues, these $50 extensions transform your existing MAXXHAUL ramps into a truly versatile lifting system that can handle virtually any vehicle in your garage. Way cheaper than buying a whole new ramp set!
