One of the most critical adjustments on a R/C vehicle is the vehicle's camber. RPM has proven time after time that even the most experienced drivers cannot set their camber by eye. With our Camber Gauge, novice to professional drivers alike can set their camber on all wheels to less than one degree of accuracy! Once camber has been set and documented, this gauge will be able to tell you if a crash has affected your camber! When used in conjunction with 70492 toe-in gauge, you'll gain a distinct advantage over anyone that does not have our gauges! Other manufacturers have camber fixtures available but the RPM Precision Camber Gauge is the only one that allows you to do trackside checks in a matter of seconds! Tech Note: The Precision Camber Gauge is capable of measuring tires with a belly height of 4.5". Monster Truck owners, please consider the RPM #70950 Monster Camber Gauge.
