2020 Silverado 1500 front brake caliper

Recommended Posts

I believe they are 2 piston calipers, I have never heard of a "6 piston caliper" 

You may want to find a more knowledgeable seller to buy your wheels from.

The offset is different on the 2019 up trucks because of a larger caliper. Thats why the previous generation truck rims hit on the front. Its not a 6 piston caliper. Need specific 2019 and up rim. There is a BB kits and option from GM .

I have a 2020 silverado  1500 LT 4wd with 5.3 engine. I am trying to determine what brake caliper size they put on these trucks? I was told I couldn't fit a 18 inch rim if it had the 6 piston calipers but I'm not sure what caliper I have.



From the factory using factory wheels, the stock 4 piston brakes (see above picture) accept a 17 inch wheel as the smallest.


The GM Big brake kit is a 6 piston kit and 20 inch wheel is the smallest.


Older OEM wheels won't fit without spacers.  See the above post from Seamus.


Aftermarket wheels you have to keep an eye out on the offsets.
