1. Check if the product provides a 2-3 inch lift requirement, some products only provide a 2-inch lift, and it is easy to pull to the limit and cause damage in off-road use after barely using a 3-inch lift.
2.Whether the diameter of the center expansion rod of the shock absorber can reach 16 millimeters or more is a basic indicator of strength.
3.Whether the upper and lower connecting sleeves of the shock absorber are high-strength polyurethane sleeves is also an important basis for ensuring long-term and high-strength use, as ordinary rubber is difficult to use for a long time under high strength.
The shock absorber is mainly used to suppress the vibration and impact from the road surface when the spring rebounds after absorbing vibration. When passing through uneven roads, although the shock absorbing spring can filter out the vibration of the road surface, the spring itself still has reciprocating motion, and the shock absorber is used to suppress this spring jumping. If the shock absorber is too soft, the body will jump up and down, and if the shock absorber is too hard, it will bring too much resistance and hinder the normal operation of the spring. Shi Xiaohui stated that during the modification process of the suspension system, hard shock absorbers need to be paired with hard springs, and the hardness of the springs is closely related to the weight of the vehicle. Therefore, heavier vehicles generally use harder shock absorbers. During modification, it is necessary to constantly try to design the optimal combination of shock absorbers and springs. Professional modification shops can generally find the best combination for car owners.
