The alternator belt on the R34 Skyline with the RB25 or RB20 is a critical component that is often overlooked until it fails under the stress of high-RPM operation, heat, or increased electrical demands from performance upgrades. The P2M Super V Alternator Belt (P2-SVB4PK890) is a high-performance replacement engineered to exceed factory standards. Constructed with Kevlar-infused EPDM material, it delivers exceptional strength, durability, and resistance to stretching, cracking, and heat degradation across a wide temperature range.

Its advanced construction provides superior performance in both cold starts and extreme high-temperature conditions commonly encountered during track days or summer driving. Backed by the manufacturer’s lifetime warranty, it offers long-term peace of mind and reduces the risk of unexpected belt failure that can leave you stranded or damage other components.
