6 splined and 6 smooth, fits 2 3/16" axle, not sure if they are for a midget or mini-sprint as I bought them off eBay and the seller didn't provide accurate diameter measurements. Nothing wrong with them, they just won't fit a sprint car axle.

Call or text for pics, can't get them to upload here.

That's interesting. Just curious what your sprint car uses,I'm not as familiar with sprint sizes. I need some but just rechecked and my midget is only 2 inch.

These were for a midget as they were only 36 spline. I believe a sprint car is 41 spline.

Sold!
