Upgrade the factory connecting rod bolts on your 2001-2010 GM 6.6L Duramax LB7/LLY/LBZ/LMM with the XDP Connecting Rod Bolt Kit XD3019RB. Constructed from Chrome Moly with a proprietary element added for additional strength.

A tensile strength between 220K-236K psi and a yield strength between 210K-230K psi ensures these bolts can handle the increased power and will not stretch like the factory bolts. These bolts are perfect for high-performance applications and are reusable when compared to some of the OEM Torque-To-Yield (TTY) bolts which much be replaced after each use.

Assembly lubricant sold separately.

Features:

• Upgraded Connecting Rod Bolts
• Yield Strength 210K psi - 230K psi
• Tensile Strength 220K psi - 236K psi
• Will Not Stretch Like The Factory Bolts
• Thread Has Been Rolled After Heat Treatment
• High-Strength 8740 Chrome Moly Construction
• 10mm Studs Test Out At A Max Load: Over 120KN
• Bolts Are Reusable, Unlike Torque-To-Yield (TTY) Bolts Which Much Be Replaced After Each Use

Tech Tips:
XDP X-TRA Slick Engine & Fastener Assembly Lubricant (Sold Separately):
The use of XD541 is highly recommended during engine assembly. Apply XDP X-TRA Slick Lubricant to head studs, head bolts, main studs, main bolts, connecting rod bolts, and any other fasteners used during engine assembly.

Using a proper assembly lubricant during fastener installation reduces friction and torque pre-load scatter in the torquing sequence, while also helping to prevent thread galling and seizing.
