Waterboxer Hydraulic Camshaft - 1900cc (DG + SP + CT Engine Codes)

This hydraulic camshaft is designed for Volkswagen Type 25 (T3) buses fitted with 1.9 Waterboxer engines and 1600cc CT air-cooled engines. It is suitable for DG, DH, SP, and GW Waterboxer engine codes, as well as CT and CZ 1600cc air-cooled engines, providing a direct replacement camshaft for engines originally equipped with hydraulic lifters.

The camshaft plays a central role in controlling valve timing, lift, and duration, directly influencing engine performance, drivability, and efficiency. This hydraulic camshaft is engineered to work with hydraulic tappets, allowing the engine to automatically maintain correct valve clearance. This results in quieter operation, reduced maintenance, and more consistent valve timing compared to solid-lifter camshafts.

Manufactured to precise tolerances, this camshaft ensures smooth valve actuation and correct timing across the rev range. It is ideal for standard engine rebuilds, restorations, or replacement of worn original camshafts where cam lobe wear has led to loss of performance, noisy valve gear, or reduced engine efficiency.

Built from durable materials and heat-treated for long service life, this camshaft is designed to withstand the demands of everyday driving while maintaining factory-style performance characteristics.
