Are they the same size as the slf2?

Yes, I also used them with xray springs. Lenghts and strokes are same. Anyone tried the 2014 or 2015 with short towers and shocks on asphalt? Any feedbacks compared to long ones?

Hi,
Are these the only parts needed to convert a 2015 diff to 2016?

- Yokomo B7-503GH6 - BD7-2016 Gear Differential 34T Pully/Differential Case
- Yokomo B7-500GM6 - Gear Differential Maintenance Kit BD7 2016

only the case B7-503GH6, you can reuse everything of the other parts

Even though the part numbers are different for the maintenance kit parts?
Mind me asking, have you tried this yourself?

I have a 2015 BD7 and want to buy the conversion kit, but dont want to pay full price for a diff if I have 3 for 2015 laying around.

Thx for your help, appreciate it.

The 2016 diff doesn't use the large outer o-ring - hence the change in maintenance kit part #. They might also use a different smaller o-ring, as the new ones are a different colour.

I believe the internals (gears+spider) are the same from 2015 to 2016 - I have built up a diff using 2015 internals and a 2016 case and it seems to build the same as an all-2016 diff.

yes, I rebuilt 2 diffs from bd7 2015 with only the new small case

all the pieces are exactly the same, the internal volume of the diff case is the same, they have only reduced the outer circumference of the pulley

@ LloydLoar: they changed the smaller o-ring, but the new black already existed with number BD-500GOB, I've always used them also with the BD7 2015 because the diff flows better, on the other hand they can seep a little oil

Just pulled the trigger on one of these bad boys, I'm going to run it in a large asphalt track. What do I need other than what's in the box?

You mean in general or tuning parts? And which of these "bad boys"? A 2016 version, I presume?

General: just the usual stuff... i.e. servo, ESC, motor, battery, receiver, pinion, wheels&tires, body.

Tuning parts: nothing's really needed. Ok, a different spur gear is kinda required if you plan to race any other class than mod. Also, many people use different O-rings in the diff (black) and the dampers (blue), also different damper bladders (black) than what comes in the kit. Other suspension mounts, mainly FF (4.2) and RR (5.7) also seem very popular, next to many other aluminium and/or titanium (coated) parts (shock shafts, pivot balls, etc.). Oh maybe upgrading the steering from plastic for the 2016 model (personally I didn't have to do that, since I converted an older car which had aluminium parts already).

If you bought a 2016 get floating servo mount or direct mount servo. You will need spare steering knuckle and rear hub carriers to get you going. I would most definitely buy things like spare diffs, turnbuckle ends, suspension blocks and springs.

so the x ray shocks are better than the yokomo shocks?I am in the process of changing over my x ray shocks for the yokomo SLF 2 as the x ray ones has a lot of play on the ball ends,but if the x ray shocks are better I think I will keep then.any advice?

I am considering buying the BD7 16 Black Series. I have a couple of questions

Does Yokomo update their cars every year like Xray? Reason I ask is that I won't be able to buy this car until a few months from now. So I wonder if they will have a 17 out by then so should I wait til the new model comes out?

Does the 16 model come with aluminum steering posts or are they plastic?

Thanks

Yokomo updates their sedan every year, but it normally isn't released until the end of the year (December-ish). This was true even in 2014, when they were already using the 2015 car at Worlds in October. Hard to say what might happen this year since worlds are in August, but I would be surprised if they released a new kit immediately after worlds (September-ish.) Stranger things have happened, though.

The 2016 comes with aluminum steering posts, but the kit bellcranks are plastic. This change was likely because they changed the kit to includes DCJs, which is a change from previous models.
