Excelente producto, a buen precio
El tensor si es original (hecho en Canadá), tal como se muestra en las fotos. Le quedó perfecto a mi silverado 2013 con motor 4.3L v6.

Works, seems solid, feels like OEM
Heavy, solid and seemingly quality. Fixed my squeeling noise. My only critique was it came in a big box with no packaging so it was probably bouncing around in transit, but i doubt it sustained any damage.

Keep your GM all GM (when you can)
2000 S-10 4.3 V6, perfect fit and performance. Appears identical to the original unit. Less than a half hour job got rid of the squeal/howl of the formerly bad tensioner pulley. Lesson learned: do the tensioner and idler together. Mine went bad within months of each other.
