Our patented K24 86 adapter plate (U.S. Patent No. D1053910) is quite different from the other adapter plates in our catalog. Due to the dimensions of the 86 bellhousing and input shaft, our adapter is twice as thick as our steel adapter plates. Because of the added thickness and increased thread depth, we were able to machine this adapter out of 6061 aluminum instead of steel and still maintain the durability we needed, although with added lightness. 

The unique shape and thickness (0.980 inch) of this plate allows plenty of thread engagement, use of any factory-style 86 clutch, fork, release bearing, and slave cylinder to be used without any modification. It also allows the K series starter to fit without modification. Significant R&D resources went into this piece, and our proprietary shape and design features are now proudly Patented!

This adapter plate includes all necessary hardware, two new transmission dowels, and a plate to block off the 86 starter opening on the bellhousing.
