Yes it would except that the Duraluminum Solid Fronts are weaker then the spring steels and when running mod, it might not want to take the stress. The spool is fine, it's the outdrive which I'm a little worried about. I might even consider epoxying the universal end with soft epoxy and running the Solid Fronts just to test it out. It might be an alternative but I'll have to try it out first since REEDY won't allow one-ways. If I can get it tight enough and shave whatever off and make it just enough so there some flex to absorb the stress, it'll last longer.

Default Diff vs. spool

The front diff-even when really, really tightned down is stil more forgiving on exit than a Spool and turns in better by far. Now-if you lock it down with epoxy or sandpaper-then its better only in the fact that a spool is lighter than a rigged up diff!!!
I run a front diff thats basically fully locked and it doesnt handle anything like a spool.

Jimmy-good point-It helps the outdrives when they can give a little on hard collsion or when one wheels in air and ones on the track at full throttle.

locking down a normal diff up front may be more forgiving than a spool. but it might not have the yank off the corner that a spool would have.

How do you think an xray evo II would react to a locked rear with a front one way? Would you need to run a GTP or lola body for extra downforce? Is it worth it for an electric?

instead of sandpaper..try replacing the diff ring with a locking washer from Homedepot. thin type..the ones that have teeth in them..

good thinking zombies. i know of some guys who have used the little pegs from traxxas slippers in their locked diffs in tc3 with succes. that could be an option too.

How tight are you running your rear diff? MIne-you can still turn it while holding the rear tires and spur. On my Tc3-You'd break skin at the same time it squeeked a little. I was wondering if I am running it a tad too loose. My car is smooth on and off power so I am hesitant to change it and ruin the balance of my car.

last time i ran my xray on carpet, i had the front diff medium tight with the rear, just like you said, i could hold the rr tires and spur and turn the lr tire.

my tc3 is the same way, both diffs are tight as hell! hehe

A properly set diff should be quite loose side to side, but have no or very little forward slip, this will result in lost accelaration, and use more battery, that is why we all run either spools or one ways in the front, to give 100% pull out of the corners.

I've discovered that the spools don't turn in as sharp as a one-way. In fact, the battery drains faster due to the added drag especially when braking or slowing down.
