Secure your exhaust manifold the right way. This stud and nut set is purpose-built for Toyota 2L, 3L, and 5L diesel engines, offering dependable fastening strength for manifold installations under high-temperature, high-vibration conditions.
Each stud includes a 5mm inner hex for clean and easy installation using an Allen key. The included top-lock nuts feature a thread-deforming section to grip tight — once torqued down, they stay down.
Whether you're replacing worn hardware or upgrading your exhaust system, this is a bolt-on solution you can trust.
