hauled 2500 lbs. of lumber on truck & 2500 lbs. on a trailer. only had 15# of air in the bags. I wanted more air but I had the tailgate down and could not get to air valves. truck was sitting on snow and ice. I am going to order the air lift compressor when I get through with this review. truck still handled well with the 15#.
Exactly as advertised
I bought this air bag kit as a traction aid for my 89 IROC. It seems well made and came with a complete installation kit and good instructions. I removed the rear springs which made it easier. It would have been difficult install the "bags" through the gaps in the coils. I can't quantify the improvement in traction but the tire marks are even in darkness and length. The kit came with two Schrader valves to pressurize the bags independently to dial it in. Recommended.
