I dont think hongnor has anything like that. The hobao spider diff should fit but the gearing is different and its not interchangeable. Iv been using a .21 and a .28 engine on my CRT for the past year and a half, never had any problems. Are you referring to the internal gears?

yeah check whether all the shims are still in place behind the gears. Check the cross pins for wear and the diff case where the pins slide in. Play around those areas can really put strain on the whole assembly. Depending on how long you have been running your truck you can expect the gears to wear and develop a sharp edge.

Th Hotbodies LSP diff gears are steel and drop right in, you can find complete diffs on e-bay and just install your big spur gear on it, I run the whole HB LSP diff in the center of my Jammin BCE PJX , i beleive the hellfire internals will work too.
