Manufactured for strength and precision, these head bolts provide the durability needed for today’s high-compression Gen V LT engines.

2014+ Gen V LT-Based Engines
LT1, LT4, L83, L86, L84, L87, L82, L8T, L8B

(1) Allen Head Bolt – Driver’s side, front hole

NOTE: On these engines it is highly recommended to clean out the head bolt threads in the block with a chaser such as ARP 912-0016 (click here) due to the thread compound that was used on the factory bolts. Failure to do so can result in new fasteners stretching or breaking before reaching final torque.
