Spool, 30 spline inner axles and drive flanges
Are you afraid your rear end may not be up to the task much longer. Here is a great option. Install this spool with 30 spline inner axles. This will eliminate two weak problems in your rear end. The small diameter 17 spline side yoke will be replaced with Tom's larger diameter 30 spline inner axles and the weak posi-trac housing with all those moving parts and slipping clutches will be gone. This will reduce rotating mass by 10 lbs! This set up is not recommended for the street guys it locks both of the rear tires together.
If your on the track this is your strongest up grade possible to eliminate breakage. Use your gears or purchase a new set on this site. We will throw in our $169.00 Master Rebuild Kit for $119.00 with this item.
