Question: CRC boasts "large diff rings" with their Gen-X diff.. Are the large diff rings going to fit my new itty bitty spurs or do I need to find smaller ones?
Cheers and thanks in advance for the many replies packed with wisdom,

All modern cars are large diff ring cars. The 78T gear is about as small as you can go but it fits fine. You are all set
