- Durability and materials: ABS plastic housings and corrosion-resistant metals extend life in under-vehicle conditions.
- Ease of installation: Direct-fit replacements with pre-assembled wires save time and reduce wiring mistakes.
- Left-right symmetry: Some GM and Ford kits specify left and right variants; verify both sides when ordering.
- OEM part replacement compatibility: If replacing worn OEM numbers, ensure the new part lists compatible OEM substitutes and cross-refs.
