Original 3.55 12 Bolt Ring and Pinion

[69 Post Sedan]

I have a used set of 3.55 (11:39) gears for a Chevrolet passenger car 12 bolt rear end. They are a matched set dated perfect for an early 1970 built car but will fit 1965 on up 12 bolt rear end.

Ring gear 3853010 dated 9/69

Pinion 3853008 dated 2/69

$200 plus shipping if needed

I can bring them to MCACN also

For me, the 3.55 rear gear with an M-20 trans is the perfect combo for a muscle car that will be street driven. Quick off the line with the low M-20 first gear, but 3.55 final drive makes highway cruising possible.

Big change from my teen years when I thought M-22 and 4.88 or 4.56 with a high winding SB was the way to go. :-)
