•Check mounting points after the first 5000 km and every 3-6 months.
•If this Truck Guard is equipped with Legacy Herd Slam Latch, periodic adjustment is required.
Refer to Legacy Slam Latch Installation adjustment instructions to properly adjust your Slam Latch.

they will minimize vibration and provide superior impact resistance.
•To help maintain the factory finish, avoid acid wash.
