Raybestos GPZ friction clutch pack module for the ZF 8HP50/8HP50Z automatic transmission. Upgraded friction material formulated to outperform OE clutch material by up to 20% in heat resistance and holding capacity, recommended for tuned/high-torque applications where the factory clutch packs are the weak link during hard shifts.

Fitment: BMW/Alfa Romeo models built on the ZF 8HP50/8HP50Z transmission - F30 3 Series, G20 3 Series, Alfa Romeo Giulia (952) with B48/B58/2.0T engines (confirm exact transmission generation at checkout).
