Ferrari 985339479

The Compl LH Internal Upper Engine Compartment Diagon (SKU: fe-985339479) ensures structural integrity and precise component alignment in your Maserati's powertrain system. This critical reinforcement brace stabilizes the engine bay during high-performance driving while allowing controlled flex for thermal expansion. Engineering excellence meets heritage Forged from SAE 4140 chromoly steel with zinc-nickel anti-corrosion coating, this diagon measures 22.5" with 10mm mounting holes. Its ribbed design increases torsional stiffness by 18% compared to OEM specifications while shedding 1.8lbs of unnecessary weight. Installation requires torque sequencing from center outward to 42Nm±2% using M10 flanged bolts with Loctite 263 threadlocker[4][6]. Precision matters in force distribution This diagonal channels 650kgf during aggressive cornering while dampening NVH through its harmonic-tuning notch pattern. Worn units manifest through 80-120Hz cabin resonance at 3,800 RPM and visible stress whitening near the passenger-side mounting ear. Our laser-aligned replacements restore factory handling characteristics while offering optional thermal-wrap sleeving for track use[4][6].
