House of Hemi Stage 2 5.7 & 6.4L VVT NSR Performance Camshaft Kit

Our Custom 5.7 & 6.4L VVT HEMI Performance NSR camshaft is designed with the naturally aspirated HEMI. This camshaft with full bolt on’s typically makes over 470 RWHP+ (6.4L) This is our most popular NA Camshaft grind we use in house.

We've ceased using aftermarket valve springs on our Stage 2 packages due to the high risk of breakage at this power level. Our NSR Camshaft delivers the same power and torque as our former Stage 2 Camshaft Package, saving customers money while ensuring engine safety and reliability with factory OEM valve springs.

Kit Includes:

• Custom Dontex Stage 2 VVT NSR Camshaft
  
• VVT Phaser Limiter Bit
• Set of Mopar Non MDS Lifters

Please Note- For engines with over 130,000kms, replacement with genuine Mopar Valve Springs is required. We've discontinued aftermarket valve springs in our stage 2 NA Applications to reduce costs for our customers.

**Upgrading your Pushrods is highly recommended to minimize valvetrain noise and replace worn factory pushrods at a nominal cost (Optional Extra).
