The Supertech valve spring kit for Volkswagen and Audi 1.8T engines is engineered for high-performance builds where increased RPM, aggressive camshafts, or forced induction demand improved valvetrain stability. The dual valve spring design helps reduce valve float while maintaining precise valve control at elevated engine speeds.
Each kit is supplied as a complete matched assembly including valve springs, titanium retainers, spring seats, and locks to ensure proper fitment and simplified installation. Lightweight titanium retainers reduce valvetrain mass, improving stability and durability under demanding conditions.
Compatible with most OEM and aftermarket camshafts within the specified lift range. During installation, installed spring height and retainer-to-seal clearance should always be verified according to engine specifications.
