Do not take any risks with the bottom end of your Cleon-Fonte engine. This genuine Renault connecting rod bolt nut is the only certified component to guarantee the critical hold of your rotating assembly. Specifically engineered for the Renault Super 5 GT Turbo, this fastener ensures maximum resistance against the extreme thermal and mechanical stresses of turbocharging. An essential part to secure your C1J engine during a rebuild or preventive maintenance.
Ignoring the replacement of your nuts when opening your engine exposes your Renault Super 5 GT Turbo to a brutal failure. On a turbocharged block, connecting rod bolts and nuts undergo permanent stretch cycles. Reusing an old nut means risking a mechanical link failure, leading to the instantaneous destruction of the crankshaft and the engine block.
Unlike aftermarket copies, this Renault rod nut meets strict specifications regarding steel strength class and surface treatment. At Optimiz Access, we know that the customization and performance of your premium sports car require components capable of withstanding high RPMs.
Wondering if it is necessary to change the nuts every time you disassemble? The answer is yes. Torque-to-yield fastening, often combined with angle tightening, stretches the material. Failing to install new hardware means accepting the risk of a rod throwing through the crankcase during hard acceleration.
Based in Hauts-de-France (near Lille and Valenciennes), our sports vehicle maintenance experts systematically recommend replacing engine hardware. Whether you perform the installation yourself or in our workshop, Renault Sport quality is your only insurance against major mechanical failures. We provide fast worldwide shipping for all our premium parts.
