Extreme precision and top quality diff case

- December 14th 2010

That's indeed the best diff case I've ever used! It's 50gr lighter than the G.H diff case and it fits perfectly to TVPs. It has also better mounting support to TVPs than G.H's case (dual screws). Diff ball bearings' housing is also a perfect fit. This case has more than enough clearance around diff cups (outside), so fitting of ANY cvd rubber boots won't be a problem at all, regardless of their thickness. Be careful though. No matter what sort of diffs are going to be stuffed in, the FLM diff output cups (FLM40030) are absolutely required. Flux diff output cups can't be used (their outer diameter is actually larger than diff case's hole). Besides the FLM diff output cups are WAAAAAAY stronger than the HPI's #86248 ones. I'm using the CEN diffs and shimming cannot be avoided in case perfect/absolute gear mess is a prerequisite. If CEN diffs are not shimmed properly (mostly on ring gear's side, 2 x 0.2 mm and 1 x 0.2 on the diff case's cover side) there's enough unnecessary play to have for no reason. Shimming is required even if you've used the right number of gaskets during CEN diff assembly, as depicted in page 11 of "GST 7.7" manual. Finally, if you're going to use this diff case, you'd better also consider buying the FLM towers (FLM43000) and drag link (FLM48000). You'll save both time and money (for extra shipping costs).
All in all, I'm really happy using this HIGH PRECISION diff case. Everything works really smooth. Congrats FLM! It's obvious you've spent a countless hours developing this perfect diff case.
