Description
ATRO HM62-64M31 is a polyurethane hood guide pin for Mack conventional trucks, replacing Mack 25QM31. The hood guide pin aligns the hood at its mounting point as the tilt hood is closed and absorbs the impact of repeated open/close cycles. ATRO’s polyurethane is engineered to outlast OE rubber by three to five times and resists oil, grease, hydraulic fluid, diesel fuel, ozone, and road salt. Made in the USA and backed by ATRO’s 3-year manufacturer warranty.
Signs You Need a New Hood Guide Pin
- Hood does not seat squarely when closed
- Visible flattening, cracking, or shearing of the guide-pin material
- Hood rocks or vibrates at the guide-pin location
- Difficulty aligning the hood with its catch on the cowl
