    GM85410 - Richmond Gear Excel Ring & Pinion Sets is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from 342 vs 410 Richmond Gear set. I recently changed the gear set from 342 to the 410 Richmond. I have only made a couple of test hits but boy what a difference it made. The car has came alive and now responds like it should. Glad I made the change. The Richmond gear set is great and I highly recommend it. Fast shipping, I ordered it on Monday night from Jegs and it arrived on Thursday and it was free shipping. I will gladly order from Jegs again.
