MAHLE CYLINDER HEAD BOLT SET TO SUIT HSV SENATOR VY VZ VE VF LS1 LS2 LS3 5.7 6.0 6.2 V8 FROM 10/2003

Head bolts play a vital role in the sealing of the combustion chamber, oil/coolant channels and ambient air. Therefore, we recommend our Mahle cylinder head bolt set for the task. Having met and exceeded OEM specifications, these quality bolts are suited for standard and mildly modified applications. These are torque-to-yield (TTY) bolts which means they are designed to be tightened past their elastic limit, guaranteeing high and uniform clamping forces. Other benefits include pre-applied sealant to the threads eliminating the use of thread locker and no-retorquing is necessary after correct installation procedures have been followed.

This head bolt set suits HSV vehicles fitted with LS1, LS2 and LS3 V8 engines.

Contents:

• 10 X Short cylinder head bolt (M8 x 1.25 x 45)
