LS1 LS2 LS3 Connecting Con Rod Bolts, Replacement, GM LS-Series 5.7L 6.0L 6.2L conrod

Set of 16 Genuine GM Gen IV conrod bolts - TTY Torque To Yield. 

Brand new genuine GM Conrod bolts for 5.7L, 6.0L, 6.2L / LS1 LS2 LS3

GM's OEM connecting rod bolts have proven to be more resilient than even GM engineers might have expected. Whether you're doing a stock rebuild, or pushing the limits, genuine Chevrolet connecting rod bolts are a great option. 

Why can’t they be reused?

TTY fasteners have an elastic quality. They are designed to stretch to a specific “yield zone.” When the fastener is torqued properly, it acts like a spring to apply consistent clamping force. However, the stretch is permanent. After they are torqued, they will never go back to the way they were.

Note: these can be tightened up to 3 times for assembly purposes. (Check your service manual for specific details.)

Do they require special tools?

TTY fasteners will require an initial setting with a regular Torque Wrench. The final setting is applied with a Torque Angle Gauge.
