Alza center diff question please help

Post by Boattrash » Fri Jul 18, 2014 9:05 pm

I was wondering what the benefits of the alza center diff is? Will I be able to use my Robinson v3 clutch with it or Is a clutch already in the assembly . Also I have the big joe 2's how will this affect my gearing as now I am using the 18 t pinion and a 44 t spur. Sorry about all the questions .

No need to apologize, that's what we are here for. When you use the center diff you don't need or use a slipper clutch and you actually have better protection. I am running the Alza CD with Trencher X' tires and I am running 11/48 on the spur and pinion. You definitely wont be able to use the 18 tooth pinion. Some on here use 9/50, 10/50, 10/48 and so on. It just depends on what you want out of your truck, how you drive and the temps. Feel free to ask all the questions you need. Good luck.

Will I need to purchase anything in addition to mount my esc? I  am guessing the stock motor will mount up with no issues.

Mounting the motor is easy and you don't need anything else for that. If you get the Vorza diff, it comes with a 48 tooth spur. I did the XL conversion at the same time I did the CD so I got the rear ESC mount from TCS Crawlers. If you plan to keep it the stock length someone else will have to answer that one. This is the ESC plate I use. ESC Mounting Plate for XL Chassis

I don't remember but you may have to order the braces separately, you need 2 they go between your TVPs and the ESC plate mounts on them.

This is what they say you need on their site.


Includes one plate (Delrin) and 4 flat head screws. To mount this, you will need the following parts (both available here on TCS Crawlers).

HPI Engine Mount Brace 7x7x74mm (2pcs) #86079
HPI Binder Head Screw M4x10mm (6pcs) #Z613

Will the truck still pull the front tires off the ground on demand with the center diff installed? I imagine it would not, but I am a brushless noob. I wondered when someone would finallly build a "bolt in" center diff option for Savages, took em long enough.

Yes, mine does but it is much more controllable. I run 500K diff oil in my CD, thicker oil will make it wheelie easier but will also reduce the protection that you gain with the CD. Everyone tunes their CD with the diff oil to their liking and driving habits.

Again I think that is a personal preference thing. I use 50K front and rear and 500K in the CD. I am not sure but I think allot of people use thinner oil in the front but I am very happy with my set up. If you start with 35 - 50K you can always tweak it later to perform more to your liking. Maybe someone else will weigh in but like I said 50-500-50 works great for me but I just bash the sh%t out of mine. That being said, trying to run mine on a track sucks unless you get good at drifting around turns. LOL! I can tell you that with the diff oil I use and the way I have the front toe set I have virtually eliminated the torque steer.

Start with 500k in the center anything less and it won't perform well.

I run 100k/500k/100k

You need center diff-usualy from HPI vorza, and suitable pinion and might 50T spur for center diff(vorza center diff comes with 48t) depend what gearing you want to have ...Check forum posts about alza cd also modules.php?name=Forums&file=viewtopic&t=98264&start=0
