Why Replace Your Flexplate Bolts?
Flexplate bolts are the unsung heroes connecting your engine's rotating assembly – yet their failure can trigger catastrophic drivetrain damage. Here's why proactive replacement is non-negotiable:
1. Fatigue & Stress: The Silent Killers
●High-Torque Punishment: LS engines (especially modified 6.0L/5.3L) generate massive torque. Stock bolts stretch under repeated load cycles, losing clamp force and allowing flexplate micro-movement.
●Vibration Amplification: Worn bolts create imbalance, accelerating crankshaft damper wear and inducing harmonic vibrations that attack bearings.
Consequence: Stranded vehicles, tow bills exceeding bolt cost 100x.
2. Corrosion: More Than Surface Rust
●Steel vs. Environment: Exposure to road salts/moisture corrodes threads, increasing breakage risk during removal. Heat cycles further embrittle compromised metal.
●Hidden Danger: Even "clean-looking" bolts may have internal thread corrosion, jamming or shearing at 85 ft-lb install torque.
3. Design Limits of OEM Bolts
●Generic Material: Factory bolts rarely exceed 150,000 PSI tensile strength. Our 200,000 PSI aerospace-grade steel resists stretch 33% longer.
●Inferior Coatings: OEM black oxide wears thin; our deep-penetration coating bonds to metal for lifetime corrosion resistance.
Why THIS Bolt Kit Solves It:
●Precision Length (0.880”): Engineered for direct crank-flange contact. Adding washers – a common "fix" for loose OEM bolts – destabilizes clamp load.
●12-Point Grip: Maximizes socket engagement, preventing rounding during 85 ft-lb torque application.
●Rust-Proof Grease Included: Not pre-coated – you control lubrication. Apply to threads to ensure accurate torque readings and prevent galvanic corrosion between steel bolt/aluminum crank.
Specification:
●M11 x 1.5 Thread Pitch
●0.880" Underhead Length
●12-Point Head
●Black Oxide Surface Finish
●Material Strength: Rated to 200,000 PSI
