Construction & Design:
Each bolt in the ARP 4U-GSE Flexplate Bolt Kit is manufactured from high-grade 8740 chromoly steel, known for its exceptional tensile strength and fatigue resistance. The cold forging process preserves the steel’s molecular structure, resulting in bolts that are stronger and more resilient than standard fasteners. Following forging, the bolts undergo heat treatment to enhance hardness and durability before precision thread rolling and machining ensure consistent thread quality and fitment.
To maximize performance and prevent galling or seizing during installation, ARP includes their proprietary Ultra-Torque assembly lubricant. This lubricant reduces friction, enabling accurate torque application and consistent clamp load, which is critical for driveline component longevity.
Installation & Fitment:
The ARP Flexplate Bolt Kit is a direct replacement for the factory flexplate bolts on automatic transmission models equipped with the 4U-GSE engine in the Scion FR-S, Toyota 86, and Subaru BRZ. Installation requires standard hand tools and adherence to manufacturer torque specifications, using the included Ultra-Torque lubricant to ensure proper bolt preload. No modifications are necessary, making this kit an easy upgrade for improved driveline reliability.
What's Included:
- Set of flexplate bolts engineered for 4U-GSE automatic transmission applications
- 1/2 oz. tube of ARP Ultra-Torque fastener assembly lubricant
- Installation instructions and torque specifications
Ideal For:
This bolt kit is perfect for owners and enthusiasts of the Scion FR-S, Toyota 86, and Subaru BRZ who want to upgrade their driveline fasteners for enhanced strength and reliability. It is especially suited for those who engage in spirited driving, track days, or any application where the factory flexplate bolts may be subjected to increased stress. Professional mechanics and performance shops also rely on ARP fasteners for dependable, high-quality driveline hardware.
