Rocker Cover Bolt, 03-14 350Z-370Z
|Quantity in Basket:none|
The factory installed rocker cover bolts (also called valve cover bolts) become brittle over time. Combined with a rather low torque requirement, and it's no wonder that the original bolts often break during re-installation. (We've even heard of a few breaking just from hand tightening!) Nissan has since superceded the original part to this replacement rocker cover bolt for 350Z and 370Z models (and most other VQ engines as well). Sold individually. See below for quantity requirements.
Be very careful when installing these bolts. While it is a superceded piece now, it still has the same low torque spec. We recommend installing the bolts by hand first (but only until resistance is felt), then follow the factory 2-step torque spec and order using an inch-pound specific torque wrench. If you aren't sure of the installation order, or don't have access to a Factory Service Manual, click here for a diagram showing the proper order. Torque Spec: 9 - 26 in-lb 1st Step; : 65 - 82 in-lb 2nd step.

Although 2015+ models require a different part number, the valve cover bolt quantity is still the same.
