GM Duramax Engine Upgrades

Cylinder Heads:
Duramax Cylinder Heads Stock heads all have “core shift” when they are manufactured. As good as CNC machining alone is there still may be a lot of material left behind. TTS follows up our 5 axis Cad/Cam, CNC machine porting with time consuming “Hand Blending” to remove material that is impossible for a CNC machine to get at, thereby further improving the airflow, while maintaining the structural integrity of the heads.

Street Port:
• CNC porting and Hand blending of ports and bowls
• Radius intake inlet port
• Precision multi-angle valve job
• New valve stem seals
• Cylinder head deck surface cleaned as necessary
• Stock components (valves Springs etc..)
• core charge applies
Race Port:
• CNC porting and Hand blending of ports and bowls
• Radius intake inlet port
• Precision 5 angle valve job
• Cylinder head deck surface cleaned as necessary
• New Ovate Beehive springs (Springs selected depend on performance requirements)
• New Stainless Steel Intake valves
• New Inconel exhaust valves
• New Bronze valve guides
• New spring cup bases

Duramax Billet Connecting Rods
| While other manufacturers are cutting corners, using imported or low grade materials, TTS has kept costs down without lowering our standards. Every rod we make is hand crafted from American made, 4340 chromoly.

When you install a set of genuine TTS connecting rods in your high performance engine, you can rest assured that the design expertise, material and craftsmanship used during production are working hard to maximize your racing effort. TTS ’s reputation and proven success has led to imitations from competing manufacturers.

Designed and manufactured using the latest in solid modeling and Cad/Cam technology. All Design and research is accomplished locally at the TTS facility. From 3d modeling and rapid prototyping to Finite Element Analysis equipment, all phases and quality control systems are all created on-site.

TTS Billet Connecting Rods come from intense research and development. Designed by TTS to strengthen the Rod and eliminate weakness at the stress points. The process requires expansive amounts of time involving product development.

Duramax Billet Connecting Rods $2750.00

 

Duramax Camshafts
Our exclusive precision ground and balanced camshafts are designed power and durability. We offer 3 versions: Street, Race and Xtreme.

Factory Cams use a single guide pin for cam gear placement. With increased power this becomes a weak point from shearing forces. TTS has strengthened this system into a keyway design in order to retain strength and reliability.

Duramax Camshafts $914.46

     

TTS Forged Pistons for Duramax 6.6L
Our forged design results in stronger pistons to work with your higher power applications and racing needs. Our Pistons are available in custom compression ratios from 14:1 to 17:1. Pistons are offered in standard and oversized bore sizes up to +.040” in .010“ increments.

(note: stock compressions is: 17.5:1 for LB7 and LLY, LBZ and LMM are 16.8:1)
