Description
- 4130 stud and nut kit replaces the stock hardware used to secure the rocker shafts
- Compared to a stock “bolt”, these JIMS manufactured studs allow the technician the assembly finesse required when torqueing the rocker arm shafts on the cylinder head during engine assembly
- These shafts not only improve the stock head configuration; they are a must in a performance application with increased spring pressure
