My apologies. I missed the VIN and RPO link originally. It looks like the ribbed dual pistons are the ones for your 4wd. I think all the limited slip (G80 RPO) vehicles had dual piston rear setups.
The non limited slip coil sprung rear axles were packaged with the same single piston caliper setup as some of the trucks in that generation I believe. The three catalogs I see show options for 2002 Tahoe with non limited slip and the pad/rotor/calipers are the same as the rear on my 2000 Sierra
Do you have any local parts support near you? Or are you forced to order online for everything?
Ah thanks.
Not easy to see everything. ☺
I haven't anything near at all regarding parts shop especially for my cars. I must order everything online and deep knowledge what is what on my cars aren't grown on trees here, it's so much easier do business in the west with you guys. ☺
If I should buy a caliper here "new", reman and non coated I will look at 373,37 dollar. I think they should put it somewhere if I speak freely.
Chevrolet also have abandon the European market so genuine GM parts did take a big turn to the wors. If you find something it's Dex-cool or filter. ☺
