WavetracÎÂ Differential Type 02J for VW Mk4 Bolt In Axles 10-309-180WK

VW Performance Parts: Wavetrac® Differential Type 02J for VW Mk4 Bolt In Axles (10-309-180WK)

Wavetrac® Differential Type 02J Bolt In Axles is designed specifically for VW Mk4 GTI/Golf/Jetta/Beetle models. Designed from a clean sheet, the new Wavetrac® Differential brings current gear technology to the market. Internally, the gear tooth forms for the Wavetrac® Differential Type 02J are optimized for strength and improved oil film retention over competitive designs. The Wavetrac® Differential Type 02J gear package is smaller, reducing overall mass, yet is more durable. Attention was also paid to the side gear/axle interface, putting as much material thickness as possible in this critical area - most important when power levels get high. Each Wavetrac® Differential is crafted from the highest quality materials available. The internal gears are made from high strength 9310 alloy steel. The diff bodies are machined from case hardened steel billet. To complete the package, every Wavetrac® differential is built exclusively using high quality, high strength fasteners from ARP®, the world leader in fastener technology.
