3 springs aren't needed. There is about 150 pounds of force on the slipper by the time you simply start to flatten the two included springs and much more when you flatten them out - and there is no noticeable slip at all with this setting(flat springs). Also, adding a 3rd spring will make it quite a PITA to install the slipper-side end cap - it took quite a bit of time and research to tweak everything so it could be built without a curse-fest - the 1st 3 or 4 versions had similar spring tension, but more spring travel and was a real b!tch assemble - always fighting the spring. :)

Sorry, I have to ask :smile:- Any updates on the availability of the 50T spur? Have they come back from hardening yet?

I would like to know too! That's all that's stopping me from ordering one right now!

me 3. Won't order the slipperential till they release, cuz a 46t is too samll for my application.

Me too, 50t still waiting .......

I have 3 or 4 prototype 50t gears - they are a little tight on the diff cup, but will function fine. 1st 3 to order the Slipperentials and request the 50t spurs get them. :)

I emailed you about it last week and got no response.

You should have received an auto-response that had the same message that was on my home page last week - I was away for the RCX show. I came home to about 900 emails, which i am working my way through. :)

I placed my order already n paid I need d 50spur thx

Roger that, Alan. :)

Is the 50T slipperential just a normal one with a larger gear or is there some difference in the diff cup? I don't see why a person couldn't use a 46T with a smaller pinion...

Well IMO smaller pinions wear faster and are harder to get a good mesh with

Hard to get 5.5:1 reduction with a 46t spur! That would require an 8t pinion, and those are only available from individuallipocells.com, and are made of unobtainium, so they are perpetually out of stock due to the limited (!!) quantities of said material.

Plus having a larger diameter spur will aid in fitting larger diameter motors (especially with smaller pinions), and also give needed clearance if mech brakes are to be employed. Plus some guys just like it big (Mix-A-Lot?)! And some also still run crts with buggy ratio diffs...

I m using a 62 spur at 11 pinion with 6s it gv me insane speed already. With 50spur I plan to use 10pinion it will b slower than 46spur n better

hi Mike wats oil do u recommend in your slipper diff, I run a CRT:) 20k?
