I have had the RC springs up front for 3-4 years, giving me a lurching jump from every bump. I just put in some TC EZ rides. Wow! Apart from the ride transformation, let me fill you in on the differences between the springs: 1) The TC spring is 1/2" shorter in overall length. 2) The TC spring has the center bolt 1/2" further forward, putting the front axle 1/2" further forward. This is about perfect 3) The RC has 5 leaves, the TC has 3 4) The TC spring eyes are not completely closed, so the grease from the greaseable bushings squirts out of the spring eye. 5) The front height is within 1/4" of where it was before.] 6) The TC springs have teflon pads, the RC springs don't. I have way more brake dive now, but it is well worth it.
