# 857355 Stay | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta stay of the late type, from the Cooling System group, weighing 0.435 kg and listed for 23 applications across the DP, SP and MS ranges. It supersedes 826421, which was catalogued earlier as a torque rod. Stay 857356 in this run is also a late-type Cooling System stay on the same 23 applications at 0.485 kg, superseding 856155 - a bracket - so the number being replaced is the clearest way to tell the two apart.
