[QUOTE="Softballer77, post: 15068852, member: 151898"] Well, i've done WEEKS worth of research. Read a lot of people who were going to go with a solid spacer to hopefully cure the whine with their gears, but sadly I haven't found anyone or threads that have given the results afterward. Maybe they feel the problem is fixed so they just don't follow-up with anyone on the forums. Idk. Anyhoo... In a week or two I'm going to install 3.90s with a solid spacer and shim kit from Ratech. Little history: I swapped my 3.31s for FRPP 4.10s and moser axles. One trip to the strip and they whine so bad, if the windows are up and the radio is off it's hard to even have a conversation. Plus, I have quite a bit of play in the drivetrain now back there, probably due to the backlash being out of limits from numerous launches. I'm already at redline going through the traps in 4th, so if I add more power, i'm going to need less gear, but didn't want to go 3.73s just yet. Like to be the guinnea on the 3.90s. When I have this done, i'm going to install the rear brake kit from Billet Pro Shop so I can run 15s. So, there will be many birds killed in one job I'm hoping. I will keep you all posted on how this all goes. AND, if ANYONE has had a positive OR negative result from using solid spacers over the crush, I'd love to hear. All I seem to hear are negatives on the crush, and nothing on the solid results. Cheers. [/QUOTE]
