2000 4x4 Blazer 4.3 -

Had a Goodyear Gatorback belt on for about the last 5 years and decided its time to replace it. Checked Goodyear & Rock Auto websites and they call for #4060950.

Got a deal on Ebay and bought the replacement but it seems a bit too short to install. The Goodyear belt that I had installed 5 years ago is a #4060952. Cheked other websites, like Summit Racing, and they specify the #4060952 for this application.

Anyone else run into this with the Gatorback belts?

 

There is 0.25" effective length difference between the two. 950 looks to be used on the 2004-2005 4.3L which is likely due to a change in a pulley diameter. I have always used the 952 on the 98+ s-series trucks without issue.

 

Hey thanks. I went ahead & got another 952 as it worked without a problem for 5 years.
