Genuine ZF Part 1238 304 394 – Sliding Block
Product Overview
The ZF part 1238 304 394 is a high-wear sliding block (also known as a shift fork pad), a vital component among critical ZF gearbox parts. This small but essential part is responsible for ensuring smooth, precise, and quiet gear selection by acting as an interface between the shift fork and the synchronizer sleeve.
Compromised or worn sliding blocks are a common cause of gear grinding, difficult shifting, and transmission noise. Replacing it with this genuine ZF part guarantees a perfect fit and restores the transmission’s original shifting quality. For ZF parts dealers and professional mechanics, sourcing this component from a reliable ZF parts supplier is key to delivering lasting repairs. This OEM sliding block is manufactured from a special, low-friction composite material designed for maximum durability and performance under constant load.
