Review on AUTOPTIM Replacement Avalanche Adjustable Extenders by Tres Carmon

The only advantage of this kit was the coil blocks on the back. The torsion keys have been indexed almost the same as the stock keys, and the dampers aren't even close. not happy with this kit and need to take keys elsewhere. wasted time. almost got the keys out and raised the rear end, but only came forward about an inch compared to the factory keys, which pushed all the way out. Skip this kit
