ARP Girdle Bolt Set, BMW / Toyota B58

ARP Girdle Bolts for BMW & Toyota B58 Engines

Girdle bolts are used to secure the engine girdle, a component that reinforces the bottom end of an engine via the main bearing caps. The girdle ties the main bearing caps together and often the entire bottom of the block, adding structural rigidity and preventing the block from flexing under high loads.

As horsepower and torque increase, it is important to use hardware that will adapt to the increased temperatures and demands of performance builds. While stock bolts fail under pressure, ARP bolts are designed with performance in mind. Composed of superior materials that resist stretching and fatigue, ARP Girdle Bolts offer much greater tensile strength and lifelong durability than stock. 

Precision-manufactured with tight tolerances and stringent quality control, ARP bolts offer consistent performance and reliable clamping force, maintaining the alignment of your main bearings and preventing crankshaft movement. Their enhanced corrosion and heat resistance make ARP Girdle Bolts ideal for demanding conditions, ensuring your engine remains secure and stable.

Torque to 25ft⋅lb

Set of 20 Girdle Bolts

Optional: Add Oil Sprocket Bolt

Fortify your BMW S58 engine with an ARP Oil Sprocket Bolt, engineered for superior strength and reliability. Unlike the factory torque-to-yield bolt, which is designed for one-time use, this high-performance ARP bolt offers increased durability and precise clamping force to withstand high-revving and high-horsepower applications.

Manufactured from ARP2000 material, it provides exceptional fatigue resistance and ensures secure sprocket retention under extreme conditions. Perfect for performance builds, track cars, and forced induction setups.

Torque to 20ft⋅lb
