Chevy/GM TH400/4L80E 34 Element Heavy Duty Intermediate Sprag Lug Type 34652A This Sprag connects the Intermediate outer Race to the Direct Clutch Drum. This 34 element sprag is a great upgrade for most TH400 and 4L80E Units since most models were assembled from the factory with 17 element sprags in them. It is a strong suggestion for all builds. It improves the holding strength and will help balance the load on the Intermediate Sprag Race. If you need a rebuild kit or parts for your Th400 or 4L80E rebuild please see our store or ask us we will be glad to accommodate all of your part needs.
