The DmaxStore Stage 1 Balanced Rotating Assembly is the ideal package for a stock workhorse or engine running around the 700HP mark.  Even if the power goals are much less, this assembly can offer peace of mind for those who abuse their engines while earning a living. This kit comes Fully Balanced.

Includes:

• 1x Callies DuraStar Crankshaft (Part# D333M81-CS)
  • Rated up to ​1200HP 
  • Callies Durastar crankshafts are designed to be substantially stronger than OEM shafts currently found in GM’s popular Duramax diesel. This improvement is the result of substantially stronger steel, considerably deeper nitride layer and unique machining features.
• Dmax Performance Connecting Rods (Part# DMAX-PERF-RODS)
  • ​Rated up to 700HP
  • The Dmax Performance Connecting Rods are built for the customers looking to run safely around the 700 HP mark. An excellent choice for a fresh engine build on a budget. Brand new direct fit for all Duramax 6.6L Blocks from 2001-2016. These Rods are recommended for daily drivers, tow rigs or mild horsepower Duramax engines.
• Mahle Motorsports Performance Cast Piston Kit
  • ​Rated up to 1000HP
  • Designed for all around engines making 400-1000HP. Machined from OE castings (retaining the cast iron ring insert) to give the same driveability and longevity of a replacement piston with additional strength necessary for modified engines. These Pistons are built for customers looking to get 100,000+ miles on a high horsepower application. Unlike some of the higher HP forged pistons which need to be replaced every 20,000 to 30,000 miles, these Mahle Pistons are built to last.
  • Application Guide:​
    • Trucks running Camshafts that do not require Piston Valve Reliefs
      • 930036055: Stock 4.055 Bore (403 Cubic Inch)
      • 930036075: .020 over, 4.075 Bore (407 Cubic Inch)
      • 930036095: .040 over, 4.095 Bore (411 Cubic Inch)
    • Please contact our sales team if you are running a Cam shaft requires Piston Valve Reliefs
• 8x Dmax Performance Connecting Rod Bearing Set (Part# DMAX-PERF-9593)
• 1x Dmax Performance Flexplate Kit
• 1x ATI Super Damper
  • Free up some horsepower while prolonging your diesel’s crankshaft life.Keep damaging crank harmonics away. ATI Super Harmonic Dampers are proven to be 30 percent more effective than stock dampers. That means a smoother running engine with improved power output—up to 12 more horsepower. ATI Super Harmonic Dampers are also re-buildable and tunable by replacing, removing, and adjusting the elastomer strips. And, since the damper bolts right to the crank hub, the timing marks are always in the same spot. So, when the marks start to move, you know it’s time to replace the elastomer strips.

Optional Parts:

• Stage 1 Callies Durastar AFO Camshaft (Part# DMAX-270-009)
  • ​Alternate Firing Order
  • No Piston Valve Relief Needed!
  • The main reason for modifying the Duramax firing order with the camshaft is to relieve stress on the front portion of the crankshaft in higher performance applications. The OEM firing order ends at Cylinder #3 and then continues from the beginning through cylinders 1 and 2. The Duramax Cranks see the most strain and tend to break right behind the first rod throw at the intersection of the second main journal (the snout). We have seen failures on anything from mildly modified daily drivers to max effort trucks. The Duramax engine Harmonics become too stressful on the cranks when getting into the higher RPM ranges and bigger power levels with the OEM firing order. With this DuraStar Alternate Firing Camshaft, cylinders 1, 2, and 3 are moved away from each other to distribute the stress of combustion more evenly and help reduce the abuse to your crankshaft.
