New March LS1 Underdrive Pulleys in stock @ Thunder Racing
We finally have a good alternative to the ever-backordered ASP pulleys 
March has just released their new LS1 Dampener pulley for the LS1 F-body. This pulley was designed in conjunction with the GM engineer who originally designed the stock balancer and has a fluid based center which prevents any timing retard issues that have been seen on some cars with other brand pulleys. We haven't dynoed one in our shop yet, but we will be sometime in the next week. Pulley diameter is identical to the ASP unit, so gains should be similar.
Pricing on the pulley is $199, but we are running an introductory special with the pulley, a new balancer bolt, and both belts for $209.99.
You can click below to order, or give us a call at 877-516-7223.
