INTEGRATED ENGINEERING DROP-IN-RODS
(For use with stock pistons)
Here at Integrated Engineering, we are constantly striving to provide a wide range of performance connecting rods for many engines and many piston combinations. For many engines, we offer multiple options in the wrist pin fits. This guide will help you to understand if your project needs Drop-In-Rods.
What is a wrist pin?
The wrist pin is the connecting point between the connecting rod and Piston, and the size of the rod and the piston need to match the exact wrist pin you are using for proper operation. Therefore, you need to purchase a connecting rod for the wrist pin supplied with your piston set. The wrist pin size is the second set of digits in the rod measurement, a 144X19 rod would indicate that the wrist pin size is 19mm and a 144X20 rod would indicated a 20mm wrist pin.
What wrist pin size does my engine use?
This is determined by your engine and what pistons you will be using in your project. Many aftermarket pistons have upgraded larger wrist pins to cope with the added stress of additional horsepower, larger pins are stronger pins. If you are using aftermarket pistons, you need to make sure you purchase a connecting rod to match. If you are using stock pistons, make sure you purchase the Integrated Engineering Drop-In-Rod for your engine application.
How do I know if I have the correct rods for my stock pistons?
Easy, just look for the Drop-In-Rod Approved Seal under the product description.
