So, after about 12 years of abuse and god knows how many miles I decided to send my 1.65 rollers to Scorpion to be checked out before putting them on my new motor. The QC dept called me 1 day after receiving them and said to me " They are worn out and we do not feel comfortable rebuilding them. We are sending you a new set". 4 days later I received a brand new set of rollers and poly locks for free. Incredible customer service, I am beyond impressed and appreciative. And very happy to see they are still Made in USA
