balancer bolt
balancer bolt Im finishing up the LQ4 to go in the car, putting on a stock LS1 balancer. Ive found two different length bolts, and was wondering which one is the correct one to use. I found a 126mm length and a 103mm length, which one is it??? Any help would be greatly appreciated!!!! 
I believe folks use the longer bolt to put the pulley back on, basically it's easier to get the extra threads into the crank and start the pulley back on to the crank. You will still use shorter bolt to finish the install. FYI, I used a threaded rod with a washer and nut to reinstall my pulley, then I put the old crank bolt back in to torque down, then removed and installed a new crank bolt to finish the install.
the longer bolt is an LS7 bolt. You need the shorter one. Personally I'd buy both and use the longer one to install the balancer. It should cost like 7-10 bucks from the dealership each.
