Shop Now for Ring and Pinion Kits for 1972-1993 Dana 70 Series Rear Axles in Dodge D300, W300, D350, and W350 trucks.
When it comes to fit, finish, durability, and ease of set-up, no aftermarket gear set equals the matched, original equipment Dana-Spicer Ring and Pinion Sets. I have been building axles for well over 30 years, and to date, I have never had a problem setting up a genuine Dana-Spicer gear set, or have we had to set up a gear set warranty. That is a track record that the aftermarket gear suppliers can only dream about. The bottom line is when you purchase a genuine Dana-Spicer gear set, you get quality equal to original equipment because it IS original equipment. When you select an aftermarket import gear set you will not get a gear set that installs and performs equal to original equipment.
