You quoted the wrong part. That is the rotor for the original 4300 and 5800. The 13.5 has the larger front bearing and takes a different rotor.irvan36mm said:Jake- Lefthander's got em. $16.00

If the sintered one is illegal at your track,you shouldn't go wrong w/a direct replacement one. If you don't already have one,look into getting a motor cooler,either from Lefthander or Crazy Ronnie. It really helps out the motor from thermalling,thus saving the rotor.

So does Tower:Sonny B said:NOV5907. Looks like Horizon has them in stock.
You possibly have one of the early models. Now the 13.5s come with the big bearing.SDL98 said:Mine actually has the small bearing and same rotor as the 4300 replacement
