Discover the Gu Patrol Castor Measuring Kit: Your Solution for Precise Castor Measurement at Home.

Whether you're adjusting castor for new radius arms after installing a lift kit or setting up a GU diff with a custom suspension, this kit ensures precise alignment to your specifications.

The kit includes one durable stainless steel measuring plate and two nut plates for secure attachment to the knuckle.

Follow these simple steps to measure castor accurately:

1- Secure the plate to the caliper mounting points on the knuckle.

2- Use a digital angle finder at the bottom of the chassis to establish your zero point.

3- Position the angle finder on the plate's edge with the arrow, and record your measurement. Remember, measurements start from 90 degrees: 90 indicates no castor, 89 indicates 1 degree, etc. The image below shows 3.4 degrees of castor (90 minus 86.6 = 3.4).

If a digital angle finder is unavailable, and the vehicle is on level ground with the diff at a typical wheel height, use a string line from the top hole to the toothed indicator. Each tooth represents 1 degree.
