The problem with this is that it has a slight flat spot on one side of the shaft where the grub screw sits and is round on the other side of the shaft it spun freely after about 5 minutes on a 2200kv motor and a 4 cell lipo before you install this item remove the grub screws pull the shaft out of the locker and grind a flat spot on both sides of the shaft or drill a hole straight through and add a traxxas drive shaft pin don’t forget red lock tight I haven’t had any issues after doing this
We bought this part to turn my son's Traxxas Slash into a drag Slash. What we found is that the part does not hold up to high torque. After three or four speed runs the shaft was spinning freely in the spool. Disassembly revealed that the set screws had failed allowing the spool to spin on the shaft. Further disassembly revealed that the torque also distorted the holes in the shaft, made them out of round and putting lips on the side of the hole. Had to file the shaft down to get the bearings off. This should work fine in "normal" applications, but not in high torque situations. On the other hand, why would you want a locked rear axle if it weren't for torque? Was fun while it lasted!
I am sure for those who are using this for the stock motor it would be fine but under 2200 KV there is no hope. I have welded this thing with red Loctite and jb weld and it didn't work. JB weld is supposed to fix everything and this is so bad that jb weld didn't work. HIGHLY RECOMEND THE HOT RACING HD LOCKER
Three laps and this thing strips out...Keep your money,save yourself some time tearing the transmission apart for no good reason,and run factory diff.You couldn’t give me a five gallon bucket full of these things
Does not fit traxxas drag slash rear differential; will put it in my other electric/nitro vehicles
Eight reviews, averaging about 2.4 out of 5, report that this locking spool works under light use but slips or fails under high torque. Recurring problems include the grub or set screws loosening, the shaft flat spots or holes distorting, and pins shearing, with failures reported after a few runs on higher-kv motors (2200kv and 3800kv) or drag use. One owner reported that a fix of flattening the shaft, adding a drive pin and thread locker kept the part working. A 5/5 review says it does not fit the Traxxas drag Slash rear differential, so fitment for that variant is disputed. Several reviewers recommend the stock differential or another locker instead.
- + Works in normal, low-torque use
- + Locks the rear axle as intended on stock setups
- + Modification with a drive pin and thread locker helped one owner
- − Grub screws loosen under high torque
- − Shaft holes or flats distort and spin freely
- − Fails after a few runs on high-kv motors
- − Does not fit the Traxxas drag Slash rear differential, per one review
