Boundary Pumps VQ Oil Pump Shims
VQ pumps can now be shimmed in the comfort of your very own garage. This shim kit includes all 3 shims. The individual shims come without accessories.
Boundary Shims raise the relief valve pressure depending on what shim is installed.
This shim kit fits VQ35DE, VQ35HR, and VQ37VHR oil pumps.
- Shims are precision cut to the bore size to prevent rocking during operation.
- Shims are laser etched to show the increased PSI (1SH +10, 2SH +20, 3SH +30)
