U Bolt 20 Inches
It prevents the spring pack from shifting under heavy braking, uneven terrain, and dynamic load conditions. Built from high-tensile steel, the 20-inch U Bolt provides exceptional resistance to stretching, fatigue, and deformation. Its extended length accommodates thicker spring packs and oversized axle configurations commonly used in heavy-duty commercial vehicles. This secure fastening supports reliable suspension geometry and improved vehicle stability.
By maintaining strong contact between the axle and leaf spring, the U Bolt reduces vibration, improves ride quality, and prevents premature wear of saddles and brackets. Its corrosion-resistant finish ensures long-term durability, especially in harsh environments. The component plays a crucial role in maintaining vehicle safety and suspension integrity, contributing to consistent performance and reduced maintenance requirements.
Key Features
- Heavy-duty 20-inch U Bolt for large spring and axle assemblies
- Provides firm clamping to maintain suspension alignment
- High tensile strength for superior load handling
- Corrosion-resistant construction for long service life
- Reduces vibration and prevents spring shifting
