I installed the steeda tri ax last night and took het for a test spin at 2am. I immediately noticed that when engine braking in third gear the damn thing rattled like hell. If I grabbed the shifter the rattle would stop. So this morning I pulled the boot off and made sure the shifter wasn't rubbing the stop bolts, it wasn't. Since I had to pull it all back apart to put the boot on I went ahead and installed the plastic washer against the brass fittings between the shift rod and the shifter. It doesn't rattle as bad noww but I think the rattle is coming from the factory shift knob. Has anyone experienced this? What aftermarket shift knobs work with the triax and fit well with the shift boot?
