Preparing new GTO high polished billet tensioner pulley!

Preparing release of matching high polished billet aluminum tensioner pulley!

SMS has been hard at work developing new products to help accentuate your engine bay! Our tensioner pulley utilizes a premium NTN bearing just like the one GM uses from the factory! Includes stainless steel hardware for nose cover and is manufactured from aircraft grade 6061-T6-billet aluminum and feature the SMS high luster show polish finish. Pulleys are manufactured 100% in the USA.

What Makes the SMS tensioner pulley better than the competition?

Every SMS tensioner pulley comes with a cosmetic nose cover

We include stainless steel cap screws to retain our nose cover

Premium NTN bearings manufactured in North America, NTN is the original bearing in your factory LS1 tensioner pulley (we only give our customers the best!)

High luster show polish not semi polished

extremely tight tolerances to keep the bearing seated correctly for long bearing life! We do not utilize a snap ring to keep the bearing seated.

Made 100% in the USA
