To measure a go kart tie rod correctly, first determine whether you are measuring the bare tie rod or the complete tie rod assembly.
For a bare tie rod, remove the rod ends and measure the rod itself from one end to the other. For the complete assembly, measure center-to-center between the mounting holes in the two rod ends.
That difference is important when ordering a replacement because tie rod listings do not always use the same measurement method. A 245 mm tie rod, for example, may refer to the rod itself rather than the total installed length with the rod ends attached.
Before ordering, also check the thread size, thread direction, and fitment so you are matching more than just the length.
Bare Tie Rod Length vs. Complete Assembly Length
There are two different tie rod measurements, and they should not be mixed up.
The bare tie rod length is the length of the rod itself with the rod ends removed. Measure straight from one end of the rod to the other.
The complete tie rod assembly length includes the rod ends. This measurement is taken from the center of one rod-end mounting hole to the center of the mounting hole on the opposite side.
When ordering a replacement, check which measurement the product listing uses. A center-to-center assembly measurement will be longer than the bare tie rod, so comparing the two can lead to ordering the wrong size.
How to Measure a Go Kart Tie Rod Step by Step
You do not need any special tools for this. A ruler, tape measure, or caliper is enough.
1. Remove the Tie Rod From the Kart
Take the tie rod off the steering assembly and place it on a flat surface. Measuring it while it is still installed can make it harder to get an accurate bare rod length.
Before removing anything, take a quick photo of the rod ends and jam nuts. It gives you a useful reference when putting everything back together.
2. Remove the Rod Ends
Unscrew the rod ends from both sides of the tie rod.
Pay attention to the thread direction as you remove them. Many go kart tie rods use a right-hand thread on one side and a left-hand thread on the other so the rod can be rotated to adjust toe.
Do not force a rod end that feels like it is tightening instead of loosening.
3. Measure the Bare Tie Rod
Lay the rod straight and measure from one physical end to the other.
Record the measurement in millimeters, since that is how most kart tie rods are listed. For example, a rod measuring 245 mm should be compared with a replacement listed as 245 mm.
4. Check the Complete Assembly Length
Thread the rod ends back into roughly the same position they were in before removal.
Now measure from the center of one rod-end mounting hole to the center of the hole on the opposite side.
This gives you the complete assembly length and can be useful when reinstalling the replacement.
5. Record the Thread Details
Before ordering, check more than just the length.
Make a note of the thread diameter, thread pitch, and which side uses the left-hand thread. Also check the chassis make, model, and any visible part number.
That extra information helps prevent ordering a tie rod that is the correct length but still does not fit your steering setup.
What Size Go Kart Tie Rod Do You Need?
For a straight replacement, match the bare tie rod length you just measured to the size listed on the replacement part.
A rod that measures 245 mm end to end should generally be replaced with another 245 mm tie rod, provided the thread size and fitment also match.
Do not choose a longer or shorter rod just because the rod ends can be adjusted. Tie rod adjustment is meant for fine steering alignment, not for making the wrong rod length fit.
Fast Kart Parts carries go kart tie rods in several lengths, so compare your measurement with the available size options before ordering.
For chassis-specific steering parts, check the exact model as well. For example, Birel ART Freeline Tie Rods should be matched by both size and chassis application.

Common Go Kart Tie Rod Measuring Mistakes
A few small measuring errors can result in the wrong tie rod showing up at your door.
Measuring With the Rod Ends Attached
The complete assembly will be longer than the bare tie rod. When the replacement listing gives the bare rod length, remove the rod ends before measuring.
Measuring a Bent Tie Rod
A bent tie rod may no longer give you an accurate reference. When the rod is visibly damaged, use the original part number, chassis specifications, or another matching tie rod from the kart when possible.
Checking Length Only
Two tie rods can have the same overall length but use different threads. Always compare the thread diameter, pitch, and thread direction before ordering.
Assuming Every Tie Rod Fits Every Kart
Tie rods are not automatically interchangeable just because the measurements look similar. Chassis-specific steering setups may require a particular rod length or thread configuration.
Using Rod-End Adjustment to Make the Wrong Size Fit
Rod ends give you room for steering alignment, but they are not meant to compensate for an incorrect tie rod length. Too little thread engagement can create a safety issue and leave you with limited adjustment.
Find the Correct Racing Go Kart Axle
Matching the replacement tie rod to the old one gets you close, but you should still check the front-end alignment before driving the kart.
Start with the steering wheel centered and make sure both front wheels are pointing straight ahead. Then check the toe setting recommended for your chassis.
Small adjustments can be made by rotating the tie rod, which moves the rod ends in or out. Make equal, controlled adjustments and keep enough thread engaged inside each rod end.
Once the alignment is set:
- Tighten the jam nuts securely
- Check that both rod ends are properly seated
- Turn the steering fully left and right to make sure nothing binds
- Recheck the toe after tightening everything
A new tie rod should not be treated as a direct “install and drive” part. A quick alignment check helps make sure the kart steers properly and the new part is set up correctly.
Go Kart Tie Rod Measurement FAQs
Bare tie rod measurements usually do not include the rod ends. A complete assembly measurement includes them and is taken from the center of one rod-end mounting hole to the center of the other.
Yes, but that gives you the complete assembly length rather than the bare rod length. Measure center-to-center between the two rod-end mounting holes while the tie rod is installed.
A 245mm tie rod normally refers to the length of the bare rod itself, measured end to end without the rod ends attached. Always confirm how the seller defines the measurement before ordering.
Not always. Many go kart tie rods use a right-hand thread on one end and a left-hand thread on the other so the rod can be rotated to adjust toe. Check both ends before ordering replacement rod ends or jam nuts.
A visibly bent tie rod may not give you a reliable measurement. Use the original part number, chassis specifications, or a matching undamaged tie rod from the kart when available.
No. The replacement also needs to match the thread diameter, thread pitch, thread direction, and steering setup used on your kart.
