### ⭐⭐⭐ LOOKS GOOD but ----
*by M***N on September 25, 2024*

Grease fitting is the wrong style you will need to replace with elbow fitting and slack adjuster is thin you will need Shimm's.

### ⭐ Does not fit
*by A***R on June 28, 2023*

This doesn't fit a 2015 Volvo

### ⭐⭐ The slack adjusters is half an inch thinner than the gunite brand so you’ll need to buy spacers
