What Does 7/8” Mean in Tie Rods?
When someone talks about a 7/8” tie rod, they’re referring to the diameter of the threaded portion of the rod.
Why this matters:
- Thicker rod = stronger steering
- Better for off-road rigs running large tires
- Prevents bending during rock crawling or heavy trail use
💡 Example: A factory tie rod might bend after one hard hit. A 7/8” heavy-duty tie rod, like the ones available from East West Off-Road, can handle far more abuse.
What is 7/8-18 in Tie Rods?
This is where the confusion begins. 7/8-18 still has a 7/8-inch diameter, but the “18” refers to thread pitch — meaning 18 threads per inch.
Think of it like this:
- 7/8” = diameter only
- 7/8-18 = diameter + thread pitch
Why thread pitch matters:
- Ensures correct fit for tie rod ends, tube inserts, and jam nuts
- Avoids mismatched parts that won’t fit—or worse, fail during a trail ride
Why Matching Thread Pitch Is Critical
Let’s say you buy a DOM steel rod labeled 7/8”. Then you order tie rod ends with 7/8-18 threads but tube inserts with 7/8-14.
Result: Nothing fits together.
Mixing mismatched threads can lead to:
- Installation delays
- Stripped threads
- Potential steering failure
✅ Pro Tip: Always confirm diameter AND thread pitch before ordering. With East West Off-Road kits, all components are matched to work together seamlessly, so you avoid these problems.
Left-Hand vs. Right-Hand Threads – The Adjustment Hack
Many off-roaders run one right-hand (RH) and one left-hand (LH) threaded end on a tie rod.
Why?
- Adjust toe alignment without removing parts
- Just loosen jam nuts and spin the rod like a turnbuckle
Before buying parts, ask yourself:
- Is it RH or LH thread?
- Does it match the opposite end?
