Buying Guide: Key Considerations When Choosing Running Board Mounting Hardware
- Vehicle compatibility: Verify OEM replacement numbers and model years. Some kits explicitly cite RAM, GM, Ford, or Dodge compatibility, while others offer broader universal fits.
- Hardware type and size: Ensure bolt size (e.g., M8-1.25 vs M6-1.0) and U-nut dimensions match your mounting points and running board brackets.
- Material and finish: Phosphate or zinc coatings improve corrosion resistance for exposed underbody components. Dacromet coatings offer extra rust protection on RAM-specific kits.
- Installation completeness: Consider whether the kit includes washers, mounting bolts, and U-nuts in the necessary quantities for a complete job.
- Replacement vs. upgrade: Choose direct OEM replacements for exact fit, or versatile kits for mixed-model fleets where compatibility varies across vehicles.
- Environmental conditions: If you operate in salted winter climates or off-road environments, prioritize rust-resistant coatings and sturdy sems bolts for long-term durability.
