DMAX Diesel Stage 1 Short Block (700hp) | 2001-2016 GM Duramax 6.6L

Years of professional knowledge and testing led us to these "Built to Last" Performance Short Blocks.

The DmaxStore Stage 1 Short Block is the ideal drop in package for a stock workhorse or a street truck 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 short block comes fully balanced with all Brand New Internal parts (Not refurbished) by our Machine/Build Shop which has been in business for over 20 years. The engine builder is a member of the Automotive Engine Rebuilders Association and has had the privilege of sitting on the AERA National Board of Directors. These Short Blocks come Digitally Balanced on the same machine that balances Ferrari and Porsche Motors to withstand 12,000RPM's.

Short Block 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.
• 1x Full set of 8 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 racing Duramax engines.
• 1x Full set of 8 Mahle Motorsports Performance Cast Piston Kit
• ​Rated up to 1000HP
• Designed for street/strip or pulling trucks making 400-1000HP that still get used as a daily driver or work truck. Machined from OE castings (retaining the cast iron ring insert) to give the same drivability 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.
• 8x Dmax Performance Connecting Rod Bearing Set
• 1x Tri-Metal Performance Main Bearing Set
• 2x Mahle/Clevite Thrust Washer Set
• 1x Dmax Performance Flexplate Kit
• 1x ATI Super Damper (Part# 917369)
• 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.
• 1x Dmax Performance Oil Pump
• 1x ARP Main Stud Set
• 1x Lower Gasket Kit
• Covers and some small parts are not included and will need to be transferred from the stock short block
