You need

Tamiya: 51055, 53379(or any other 3mm diff balls), 53030

Yokomo: ZS-501, ZS-506, ZS-507, ZS-508

If you don't have the LW suspension you need tamiyas 46mm driveshafts-51092(steel) or 53724 (alum)

RC Alum Diff Joint Set - TRF415
Item #53889 (COMING SOON)

High precision aluminum parts allow diff adjustment without removing joint from chassis, and are easy to perform maintenance on.
*Compatible chassis: TRF415, TRF415MS, Chassis with Item 49378 TRF415MS Up-Grade Parts Set, TRF415MSX

can somebody explain just what they are talking about? how would i adjust the diff without taking the dogbones out of the drives? what am i missing here?

Probably a bit like the Xray. Instead of having a screw head (hex) there is just a hole in the outdrive and a holes which goes throught the screw head. Line these up then turn one way or turn the other to make the adjustment. of course you'll need to hold the opposite wheel.

Yes that´s true. Someone here makes aluminium diff halves for a front diff. I have to say I also bought the diff halves but never tried as I like the oneway very much. Also we don´t run foams so you don´t need a frontdiff really.

Problem is, to get that to work on the 415 diff, the thrust race would have to be on the other side, as at the moment the head of the bolt is right in the place where the bearing goes...
I was discussing this with TRF415boy at the weekend. And the conclusion was that without a redesign of the internals, it would be darn hard to do that on the car as it is.

Recently I was looking at the setup sheet and can anyone explain to me what "rebound stroke" is.

Thanks

Is it similar to droop?

I believe it's one in the same! Just another name for the same thing!

Rebound stroke is the same as droop. But it could be measured differently on different setup sheets/drivers. Some measure it with wheels off the car sitting flat on a setup board. They measure the top of the axle. Alot of Tamiya drivers use this method. Measurements will be like 24.5mm or 25mm. Another way is measuring droop under the arm or hub using a droop gauge. Another is with car sitting on setup board with tires on. Then measuring ride height. Then raising chassis up until the arms bottom out on the droop screws or til tires lift off the board and measure the chassis height and subtract the ride height from that to get rebound stroke. And I'm sure there are tons of other ways too...

Alex Springs are shorter than Pro4's. Alex are more like Yokomo springs.

Yes, there's an old TA04 thread here on rc tech somewhere. Advanced search should bring it back.

I´m talking about the black HPI springs with just the small colour code point on top of the springs. These look the same as Alex springs and a HPI guy confirmed this.
