hello i have a rc18t and the rear diff keeps stripping is there something i can put in other then the plastic ones? thanks for any info

only stock ones are out there, are you shimming it ?? what motor are you running ?? my front one was making noise with a 6800 mamba on hard braking, but the shim kit fixed it !!

i havent tried shimming it , i am running the mini max motor

Yes You need to shim it to adjust bevel gear play. We sell a shim kit. Also make sure the diff is not too tight.
