Description

ARP Main Stud Kit (151-5405) - Ford Fiesta ST150 / Duratec 2.0L & 2.3L ('03+)

Elevate the foundation of your high-performance Duratec build with the ARP 151-5405 Main Stud Kit. Engineered specifically for the 2003-and-later Ford 2.0L and 2.3L Duratec engines (found in the Fiesta ST150, Focus ST170, and various Mazda applications), this kit replaces the factory torque-to-yield main cap bolts with premium, reusable fasteners.

Crafted from ARP's renowned 8740 chromoly steel and heat-treated to the exacting standards that define motorsport dominance, these studs provide a dramatic increase in clamping force and fatigue resistance. The precision-rolled threads ensure perfect, consistent torque application, creating a rigid, unchanging backbone for your engine's rotating assembly. This is critical for maintaining perfect crankshaft alignment and bearing integrity under the extreme stresses of forced induction, high-RPM operation, or aggressive street tuning.

The kit includes all necessary studs, washers, and nuts for a complete installation. By distributing load more evenly and eliminating the stretch characteristics of OEM bolts, the ARP Main Stud Kit is the definitive insurance policy for your block's lower end, allowing you to push power limits with confidence. A fundamental upgrade for any serious rebuild, turbo/supercharger conversion, or endurance-focused Duratec project.

Key Features & Applications:

Direct Fit: For 2003+ Ford Duratec 2.0L & 2.3L engines (Duratec 20/23).
Core Reinforcement: Secures the main bearing caps to the engine block, forming a rigid foundation for the crankshaft.
Premium Materials: Manufactured from high-strength 8740 chromoly steel, heat-treated for maximum durability.
Reusable Design: Unlike stretch-type OEM bolts, these studs can be torqued repeatedly without performance loss.
Essential for Performance: A mandatory upgrade for engines undergoing forced induction, significant power increases, or competition use.
Common Vehicles: Ford Fiesta ST150, Focus ST170, Focus Puma (Duratec R), Mazda 3/L5 2.3L, and related Duratec/MZR applications.
