RING SET 850+.040 GRANT
Grant brand piston ring set, +.040 oversize, for an 850 engine.
This is a Grant piston ring set sized at +.040 over, for an 850 engine. The listing doesn't specify make beyond that, and the manufacturer code on file doesn't line up with what a ring set actually is, so take that tag with a grain of salt. Ring sets like this one are sold to fit a rebore that's already been taken out to the stated oversize, so it only works if your cylinders have already been machined to +.040.
