Technical Description and Features

This suspension strut and coil spring assembly features a compressed length of 16.22 inches and a travel length of 7.40 inches, allowing for effective shock absorption and suspension travel. The spring is made from 55crsi steel, known for its strength and durability, while the housing is constructed from Q235b steel, providing a robust frame for the assembly. The relaxed length of 23.62 inches ensures proper fitment and spring tension. The assembly mounts with a bracket hole on the lower end and a bolt on the upper end, matching factory specifications for the Toyota Highlander. A dust shield is included to protect internal components from debris and extend service life. This assembly does not feature adjustable damping or rebound, nor does it have a progressive spring rate, aligning with regular grade suspension requirements.

Common Applications and Problem Solving

• Replacement for worn or damaged suspension struts on Toyota Highlander vehicles
• Restores proper ride height and suspension travel
• Improves vehicle stability and handling by maintaining correct spring tension
• Addresses noise or vibration issues caused by failing struts or springs
• Prevents premature tire wear related to suspension component failure

Installation Notes and Tips

Installation requires removal of the existing strut and coil spring assembly. Note that mounting hardware is not included, so original bolts and brackets should be reused or replaced as needed. Proper torque specifications should be followed for both upper bolt and lower bracket hole mounts. It is recommended to have a professional alignment performed after installation to ensure optimal handling and tire wear.
