High quality aluminum, not the average plastic ones!
This is a good upgrade for your truck, but be aware you might have to do a little modification to it. Mine wouldn't fit into the hole so had to grind the metal sleeves down a little cause they don't flex like the OE plastic ones.
Works as expected! Great product!
Perfect fit. Seal was much better than the plastic counter part
Metallic, looks sharp and is a quality product. Has performed well. Perfect fit.
Excellent fit, and their video installation library is always extremely helpful. The video library is the main reason I shop at 1A Auto.
Fits great. Just as the picture depicts.
Perfect fit no hassle easy to install
I wanted this to work. It looks heavier duty and nicer than OE. But it was too big and did not fit. I did not want to force it in or modify the part.
Worked great, super high quality. Very easy to install utilizing the videos online.
Currently, we do not carry this part for your vehicle. We're always updating our inventory so please check back soon!
Yes the body is aluminum
Yes...this fits...my 2014 Sierra has the exact same motor....only difference is it's chrome for whatever reason and factory one is not but mine fit and worked great! I've also installed one on a 2018 Silverado with a 5.3 belonging to a friend...good luck
