Matthew Lambrecht owner/proprietor of Caliber Customs in Madera CA was tasked by me with making a set of lift arm extensions for my MaxJax two post lift. Ordinarily, the MaxJax lift can accommodate most passenger cars under 6000 lbs, however in the case of Captain Proton, my Ariel Atom, it wasn’t able to do so based off of the exoskeleton design. Matt designed/fabbed up a set of lift arm extensions and now I have a completely functional lift for all my cars.
The arms function on an abutment principle which wedges the extension at the end of the existing lift arm. Each extension was fitted to a particular arm to ensure a very tight fit. There is virtually no play. Further, the mounting point of the arms are reinforced with a tab that sits inside the square tubing and is spot welded through the main flange. Conservative estimates are that the sheer strength of the mounting dowel is an excess of 30,000 pounds and working load of each arm is approximately 2000 pounds, well in excess of the lifts design specifications. So no laying on my back or wrenching on my knees for the first round of upgrades coming this spring.
