I have an old TC3 that is set up for drifting. It works great, but I need more traction on the front end. Is there a way to lock the front diff without hurting it or buying the one way diff setup? I can drift fine, but I cannot make any accurate turns, especially at higher speed. Thanks in advance.

just tighten the ball diff some and loosen your shocks so u get more weight transfer in the front

If I over tighten, I can break the screw, correct? I have tightend it until I feel resistance, then I backed it out a 1/4 turn. It drives great now, but will this hurt the ball diff? Thanks in advance.

I also have a TC3 and I am running it with the front diff locked and the rear one with thick grease and a bit tight. Here is a link on how to lock a ball diff.

and go to how to lock diffs

and here are some pics of my TC3

as long as its not too tight ur diff should be fine. also on the tc3/4 diffs if u over tighten the screw, the nut will break before anything gets damaged

Thank you for the info, it is much appreciated.

also bro fyi u may want to go for steel diffs too, they make hella difference in durability

A simple but effective way to get locked diff performance without any damage - remove the diffballs, the diff washers then have much greater friction to overcome before slipping
