Hardware (bolts, nuts, etc)
Your local Tractor Supply Co. will have the most options and best prices on bolts, nuts, washers, and more. Home Depot & Lowes do not have the best selection for hardware.
McMaster-Carr is great for ordering bulk online hardware and getting it in a 1-2 days.
Motor Sprockets
Front Motor Sprocket ** Go to “Sprockets for ANSI Roller Chains”. Scroll down to size 35 chain. 7/8″ shaft diameter. 3/16″ keyway.
Rear Motor Sprocket (chain #35 split sprocket. Choose from 53-85 tooth. Recommended to have multiple different sizes for testing)
Keyway Item #98535A140. 3×16″ x 3/16″ spring steel machine key stock.
Size 35 Chain (Will need to adjust size using chain break or master link)
Chain Break Tool (In case your chain does not have a master link)
Go-Kart Tires
See the current evGrand Prix rules to determine if there is a tire spec and what tire is spec.
Tire Pressure Gauge To fill the tires, no need for fancy air compressors or tanks. A classic bicycle pump would work just fine. The gauge can release pressure to where you want it.
