Ensure proper wheel "dish" or centering with Park's WAG-5. Effectively measures the distance from hub locknut to rim sidewall with no tire removal required. Compare this measurement to the wheel's opposite side to determine dish adjustment and confirm a perfectly centered wheel. Invaluable for impossible to eyeball rear wheels and disc wheels where the rim isn't centered over the hub flanges.
Dissembles quickly for easy storage and transport. Compatible with all hub designs and 16 Inch to 29 Inch wheels (ISO 305 to 630). Requires tire removal for use. Made in the USA.
