Grounding Kits
Grounding Kits: HKS Circle Earth System
Every electrical circuit in a car returns through ground, and factory ground paths through the body and engine pick up resistance over time from corrosion, paint and loose connections. Adding dedicated ground wires gives current a cleaner path, which can help ignition, sensors and electronics perform consistently.
OneFastShop carries the HKS Circle Earth System, a universal grounding kit that links key points in the engine bay and chassis with dedicated ground wiring. We also stock the matching HKS Circle Earth 3 meter wire kit and terminal set, so you can extend an existing install, add more ground points, or replace worn parts.
We are an authorized HKS dealer, and every part is genuine with full manufacturer warranty. Need help planning ground points on your car? Our team is happy to assist.
