How do I know what size connect rod to get?
Measure the length of the metal between the end of the connecting rod and its inner diameter, taking the measurement as close to center of the rod end as possible. Perform this measurement on both ends, then add the numbers together. Add the total to the sum of the halved inner diameters.
What are the different types of connecting rod?
Following are the types of connecting rod, used in various types of engines:
- Plain type rod.
- Fork and blade rod.
- Master and slave rod.
- Billet conrods.
- Cast rods.
- Forged rods.
- Powered metal conrods.
How do I choose a connecting rod?
In addition to engine power and rpm levels, other factors important to connecting rod selection are:
- Application: street, drag race, endurance racing, etc.
- Engine dimensions: stroke, rod ratio, piston height, etc.
- Rod weight vs. reliability.
- Budget (for most of us, it plays a role)
What is connecting rod ratio?
Rod ratio is the mathematical relationship between the overall length of the connecting rods and the stroke of the crankshaft. Divide rod length by the crank stroke and you get the rod ratio. For example, say you’re building a stock small block 350 Chevy with 5.7- inch rods and a 3.48 inch stroke.
How are rods measured?
In modern US customary units it is defined as 161⁄2 US survey feet, equal to exactly 1⁄320 of a surveyor’s mile, or a quarter of a surveyor’s chain ( 51⁄2 yards), and is approximately 5.0292 meters….Rod (unit)

| imperial/US units | 161⁄2 survey ft |
| metric (SI) units | 5.0292 m |
How does rod length affect piston speed?
While average piston speed is not affected by rod length, there is a difference in piston speed at varying points through the stroke. Shorter rods are faster through mid-stroke and spend less time at top dead center, while longer rods are slower through these areas but spend less time at the bottom of the stroke.
What is the connecting rod material?
A connecting rod with a tension load is made of forged steel, cast steel, or fabricated steel. Rods with a compression loading are cast nodular steel or aluminum alloy.
Which material is best for connecting rods?
ALUMINIUM CONNECTING RODS: Aluminium material can be used for manufacturing of connecting rod due to its light weight preferred over steel and titanium materials and also has high shocNing absorbing capacity. It possess superior strength ratio than steel.
