ARP Bellhousing Bolt Kit for GM V6/V8 — 129-0901 (Vehicle-Specific), High-Strength USA Made

ARP 129-0901 is a vehicle-specific bellhousing bolt kit engineered to securely fasten GM V6 and V8 bellhousings with high-strength, corrosion-resistant hardware manufactured in the USA.

When swapping transmissions or rebuilding drivetrains on GM V6 and V8 engines, using the correct bellhousing bolts is essential for safety, alignment and long-term reliability. The ARP 129-0901 kit supplies the exact hardware intended for GM bellhousing applications, packaged to vehicle-specific fitment standards and produced to ARP's quality specifications in the United States.

What components are included in this ARP bellhousing bolt kit?

The kit contains the bolts and related fasteners needed to mount GM V6/V8 bellhousings to the engine block. ARP designs each kit for complete fitment so you don't need to mix hardware from multiple sources.

• Correct count and lengths of bellhousing bolts for GM V6/V8 applications
• Precision-machined threads and heads for consistent torqueing
• Packaging sized for compact storage: 14.8 × 1.8 × 9.8 cm
• Lightweight kit weight: approximately 0.202 kg

How does ARP 129-0901 improve installation and serviceability?

Using a vehicle-specific kit eliminates guesswork and reduces the chance of installing incorrect bolt lengths or grades. These bolts are manufactured to tight tolerances so torque readings are repeatable and the fasteners maintain clamp load under repeated service.

• Exact-fit hardware reduces installation time and rework
• Consistent thread engagement prevents cross-threading and misalignment
• Appropriate head style for common wrench and socket tools
• Clear packaging helps identify contents during service
