As power levels increase, the bottom end must be capable of handling sustained torque and heat just as reliably as the rest of the engine. The 034Motorsport Main Stud Kit for EA839 2.9T/3.0T reinforces the engine foundation by improving main cap retention and maintaining consistent clamping force under prolonged high-load conditions.
Manufactured from premium tool steel with laboratory-verified tensile strength beyond 260,000 psi, these main studs address the limitations of factory fasteners that can lose clamping force over repeated thermal cycles. Fully reusable and engineered as part of a system-level approach, they help future-proof performance builds by promoting long-term durability, stable bearing alignment, and confidence during extended high-output operation.
Product Description:
The 034Motorsport M10 Main Stud Kit for EA839 2.9T/3.0T is engineered for high-power builds where increased torque and sustained load place greater stress on the engine's bottom end. As output increases, factory main bolts can become a limiting factor, particularly during repeated thermal cycles and prolonged high-load operation. These M10 main studs are designed to provide the additional clamping force needed to support higher power levels with confidence.
Constructed from premium, high-strength tool steel and laboratory-verified to deliver tensile strength beyond 260,000 psi, these reusable main studs help maintain consistent main cap retention and stable bearing alignment under elevated torque and heat. This added bottom-end security is critical for aggressive tuning, track use, and other demanding applications where reliability at higher power levels is essential.
If you are already in the engine installing main studs, this upgrade pairs perfectly with our Bottom End Package for EA839 2.9T or EA839 3.0T to reduce multiple stress points at once and maximize long-term durability. Together, these upgrades help support higher power levels with greater confidence under demanding use.
