Purchase Connecting Rod Bolts

Gen 3 / 4 Rod Bolts Extensive testing by Katech for GM’s LS1 ASA engines showed the production rod bolt to be the weak link in the stock bottom end in the LS1 engines. Our rod bolt is the best you can get and fits production connecting rods without having to re-hone them to size.

These direct replacement bolts are made from H-11 material for extremely high tensile strength with threads rolled to J-graded specifications. To install the new bolts, simply remove the old bolts and feral that hold them in the rod cap. Then insert the new rod bolts, apply a light coating of supplied lubricant to the threads and torque to 50ft.lbs. Using the Katech rod bolts will increase your engines RPM and Horsepower potential.

• H-11 high tensile material - 200,000 psi yield strength
• Bolts directly in place, no resizing necessary
• Extended RPM usage
• CMD lube (for steel rods) included
• Now fits LS7 also (requires Dow Molykote 1000 lube - sold seperately)
