Product Details
Genuine VW/Audi Lower Block Assembly Hardware Set
- Bottom-End Rebuild: Complete collection of critical fasteners required when splitting or refreshing your engine block's bottom end.
- Torque-to-Yield: Every bolt in this set is a stretch fastener designed for single-use clamping accuracy.
- Zero Risk: Never reuse old bottom-end hardware; stretched bolts lose their tensile strength and risk catastrophic backing out or snapping.
- Factory Spec: Sourced as direct OEM replacements to guarantee exact thread pitch, length, and tensile strength under extreme engine loads.
Primary Vertical Main Bearing Cap Bolt (N91118902)
- Core Clamping: Secures the main bearing caps directly to the engine block to cradle your crankshaft.
- High Strength: M10x80mm multi-tooth construction engineered to withstand extreme rotational combustion forces.
- Must Replace: Stretches permanently upon installation to deliver maximum, uniform bearing crush.
Horizontal Cross-Girdle Main Cap Bolt (N91187501)
- Block Rigidity: Threads horizontally through the side of the engine block directly into the sides of the main caps.
- Stop Distortion: Prevents main cap "walk" and block twisting during high-RPM, high-boost operations.
- Triple Square: Precision M8x50mm triple-square drive head prevents stripping during high-torque assembly.
Long Accessory Bracket Mounting Bolt (N10765501)
- Heavy Duty: Anchors the heavy-duty alternator and A/C compressor accessory bracket to the engine casing.
- Vibration Resistant: Long M8x85mm shaft distributes accessory drive torque and dampens belt vibrations.
- Perfect Alignment: Ensures accessories remain perfectly parallel to the crank pulley to prevent belt throw.
Accessory Tensioner / Pan Perimeter Bolt (N10766301)
- Tensioner Anchor: Secures the accessory belt tensioner assembly or upper oil pan perimeter to the block structure.
- Clean Seal: Provides the exact, uniform clamping force needed to compress structural block seals without stripping.
- Direct Fit: Premium M8x20mm Torx fastener matches factory thread depths perfectly.
