Exhaust Manifold Locknuts

New!!! Prevailing Torque lock nuts for your 3SGTE exhaust manifold. Loose exhaust manifolds and turbos are now a thing of the past!!!

These prevailing torque all-metal locknuts are Grade 10 zinc-coated, and use a 17mm wrench for installation. The outer threads deform when torqued into place, so they hold tight under both extreme vibration and extreme heat.
