Pro1's are more general purpose and are the ones installed on a stock Revo out of the box.
yes i want to use these but you said the erevo comes with LT on it right and mike said it actually comes with other rockers so all have to do is swich the rockers to p1 right.
I guess you misunderstood. The stock Nitro Revo comes with P1 and LT rockers/springs.
But yes, if it comes with the P1's, you can easily switch them out. Once you know which ones works for your application, you can get the blingy Al rockers. :)
