Designed To Withstand Pressure Where OEM Fails

The SunCoast 6R-LDS Locking Dipstick is engineered for the 2011–2017 Ford F250 and F350 6.7L Powerstroke, addressing a known weak point in the factory transmission setup. Under heavy load or during high-performance use, factory dipsticks can work loose due to heat, vibration, and pressure spikes, allowing fluid to escape or contaminants to enter. This dipstick locks securely into place, eliminating the risk of blowout and ensuring fluid stays where it belongs. Built from durable materials and tested under extreme conditions, it holds up to the demands of diesel applications, whether on the job site or at the track. The design is based on SunCoast's failure analysis of OEM parts, meaning every detail was crafted with purpose and real-world performance in mind. It installs easily without major modifications and provides a long-term solution for drivers who push their trucks beyond factory limits. For anyone building a reliable transmission system, this dipstick is an essential upgrade.
