Bulletproof diffs .....

[DGCON]

Bulletproof diffs seem to be a must . I have a savage Xl and am beefing it up .
My question is when I get these is there anything else I should upgrade with it . I'm looking at GH aluminum bulks .but I just seen the composite gearbox/bulkhead from hpi part #102272
I see it's just the gears for the diffs.

I also see on eBay they have chopped bulletproof flux differentials for $50

IMO i would stick to the composite bulkhead from HPI. I have heard ppl complaining about stripping screws wwith the GH ones. Alos the composite ones will still give a bit of flex.

Over here in aus, my lhs wants $54 just for the composite bulkhead case, so I did what your saying and got mine from ebay.
Cant beat 2 complete diff, towers, some braces, bulkheads ect for $50 + postage and kept the towers and stuff for spares 🙂

I wouldnt call them a "must" but a lot are running them and like them. i was just telling b/r i still have the stock flux diffs in my flux and the b.p. on my bench caz its hard to get motivated to replace a part that is in perfect working order.

i think they haven't stripped caz of my GH bulks.

i will agree that you prolly don't "need" alloy bulks in most cases as the composite are gonna be strong enough for most applications.

i haven't had the screw-stripping issue on my GH & you don't want any flex in a gearbox of any kind. Flex will disrupt the precise mesh of your gears and will usually result in failure.

Not sure if there is any oil in them, i should actually check them LOL

how old is your XL? HPI switched to BP ring & pinon gears in the XL at some point.

If you guys are using stock diffs still and haven't opened them then you SHOULD have grease in them.

I Thought the flux came with bp diffs stock! I went to bps in my xl. They have helped, My bearing are what i distroy the most!

Or at least hope it still has some grease in it! When I got my flux I am pretty sure it was the old style diffs not the bp. Looking to upgrade soon anyway!
