I didnt buy my aluminum racing jack because its a racing jack. I bought mine because its less than 44lbs. Hell of a lot better than its comparable steel one at 115lbs. I hate hauling a 100+ lb jack around when the less than 44lb aluminum "racing jack" is light enough to pick up and move around and is soooo easy to roll into position even if the floor isnt perfect. The solid front wheel does wonders on bad ground or pavement. And its nice to push the handle once and have the jack on the vehicle and ready to go. My old steel jack took forever just to pump it up to position.
Thats why people buy "racing jacks"
