Transdapt Differential Cover - Chrome, Steel, Direct Fit, Kit
$56.49
Q:I’m looking for a chrome rear differential cover for my 2001 Chevy Silverado 1500 standard cab which has a 10 bolt differential cover on it, and I’m having a VERY hard time finding one. On a couple websites it says that the Transdapt 9037 cover fits my truck, but then 3 other sites say that it doesn’t fit my truck. So frustrating!!! And most of the reviews I’ve read on that part say that the bolts that come with it aren’t the right thread pattern for their trucks. Which leads me to believe that it probably doesn’t fit. But your website says it does. Can someone please help me with this?!!! Show Less
RANDOLPH S.
A:BEST ANSWERHi Randy, I'm happy to assist you. If your 2001 Chevrolet Silverado 1500 has the 8.5 inches differential with 10 bolts, then this part can fit.
