JR Motorsports sent over the rods and pistons preassembled, but we pulled them apart to inspect them and check the weights-which turned out to be well-matched from rod to rod. When assembling pistons and rods, always make sure to use plenty of assembly lube-Royal Purple's synthetic assembly lube in this case. Install the pin lock on one side and slide the wristpin in place joining the rod to the piston. One side of the rod has a chamfer on it, make sure it's oriented with the piston so that the chamfer points outward (not facing toward the other rod on the journal).
