Very nice piece of equipment, easy to install and over all smooth operation. Very good buy, highly recommended compared to stock diffs. Special note is to have the old directions with you for install or on a scratch paper mark in which direction the stock diff was taken out to save sweat and tears later.
This is one of the best upgrades you can buy for your TT-01. It must be used with the 3Racing swing shafts, which may put you off since it will cost quite a bit for two sets front/rear, but it really is two upgrades in one that will improve the handling of the TT-01 tremendously. It can be (and was, in my case) used straight out of the box for drifting..it even comes with bearings! It also looks very nice, it may be a moot point since you won't actually see it once it's installed, but until you get around to it it's very impressive to look at.
Getting LSD's in your car will be the best thing you've done to improve the handling, I'd recommend this before getting new suspension.
Very good upgrade part for tt-01. It helps the model turn smoother or drift better depending on the set-up. It comes completely assembled with ball bearings and all. Needs only a little bit of grease and the 3Racing swing shaft.
Awesome as is everything that I have bought from 3 Racing. Very smooth operation and very easy to adjust. The gear is made is nylon i think as it seems to last forever. Also the fact that the outdrives are hardened steel is a bonus. I cant say enough good things about 3 Racing products.
