Air Helper Springs

Installed these on my 2014 Audi A6 tdi. I pull my work trailer everywhere with my car and my car always looked horribly squatted. I installed these helper springs in like 15 minutes per side using only a Jack, lug wrench, and a quarter inch drill bit. It leveled out my car with the trailer hooked up, with 35 psi in each. I hit a deer with that car and forgot to take off my hitch and helper springs, so now I have to buy new and do a fresh install on my 2013 Audi A6 3.0t. The springs are the same size as the Volkswagen counterpart vehicles, and they weigh around the same amount roughly. Bottom line, I would recommend them to anyone who would benefit from the advantages of helper springs, and I’m buying another set once I’m done writing this review.
