ARP (Automotive Racing Products) makes the strongest fasteners in motorsport — head studs, main studs, rod bolts, and flexplate bolts used by every Formula 1, NHRA, NASCAR, and championship motorsport program. Aerospace-grade alloys, exact-fit machining.
The ARP 204-5409 Main Stud Kit is specifically designed for Audi 5-cylinder engines produced in 1996 and earlier. As these engines become more popular for high-performance builds, protecting the bottom end is critical. ARP studs offer significantly higher clamping force than OEM bolts, ensuring that your main caps remain locked in place even under extreme stress.
Building a high-performance engine requires components that can handle the increased pressures of modern tuning. The 204-5409 kit provides the structural integrity necessary to push your classic Audi engine to new limits without worrying about bottom-end failure. These studs are heat-treated and stress-relieved to ensure long-term durability in the most demanding conditions. Upgrade your engine today with the best fasteners on the market, available through GGCRACING.
