Tech Insight

Under heavy load or high fluid temperatures, transmission pressure can force a standard dipstick upward, causing leaks and fluid loss. Lokars Anchor-Tight locking system mechanically secures the handle, preventing blowout and ensuring consistent sealing.

Firewall mounting keeps the dipstick away from headers and moving drivetrain componentsimproving serviceability and long-term reliability in performance builds.
