Review on ECCPP 1 5 6X5 5 6X139 7Mm Compatible by Polo Acri

They work well, one thing is that when you open them they are coated in some kind of grease. Clean the threads and lug nuts after cleaning the brake as this will prevent them from being tightened properly. Make sure you tighten both the spacers and lug nuts to the manufacturer's specifications and not to some arbitrary number like 100 ft-lbs. Chevy/GMC weighs 140 pounds. for your information. Recheck spacer nuts and lug nuts and retighten them after 50-100 miles as new studs usually stretch a bit. 👍🏻
