Ascender 傳動軸轉接座

Finally got my stock driveshafts to fit without any wobble. The heat treating is clearly legit, held up through a whole afternoon of rough bashing without a hint of wear on the pinion output.

The machining on this chromoly steel adapter is flawless, threads went in smooth as butter with zero binding. My driveshaft now runs true and quiet where the stock setup had wobble.

Swapped out the stock plastic piece and this adapter locked in perfectly with the 5mm pinion output, so my standard driveshafts fit without any grinding. The heat-treated chromoly steel hasn’t shown a hint of wear after a few rocky runs, which is exactly what I wanted.
