Challenger 10500 Turning Radius Gauges Mechanical Alignment Set The Challenger 10500 Turning Radius Gauges add wheel alignment capability to compatible Challenger four-post lifts without a dedicated alignment rack. Sold as a set of 2, these mechanical turn plates measure caster, camber, and toe-out angles during alignment procedures, requiring no electrical power, pneumatic connections, or hydraulic systems. The 10500 is compatible with the Challenger 40 Series, 4P14 Series, 4115/AR4115 Series, 44018AR, and 4030/44030AR lift families, allowing a single gauge set to serve multiple lift models. It is 3D alignment capable when paired with compatible Challenger bolt-on alignment kits (Part #40200-3D series), integrating into a modular upgrade system. It is available in standard powder-coated (10500), heavy-duty powder-coated (10500HD), and stainless steel (10500SS) variants, with stainless resisting corrosion in high-humidity or coastal environments. Backed by Challenger's 1-year limited warranty. ⚠ California Proposition 65 Warning WARNING: this product can expose you to chemicals including styrene and vinyl chloride, which are known to the State of California to cause cancer, birth defects, or other reproductive harm.
