- Dustproof protection: blocks dust, sand, moisture and other small particles from entering the CV joint, reducing friction and wear and extending the joint life. - Front or rear compatibility: suitable for front and rear CV joint assemblies and can be used with constant-velocity joints, ball joint dust covers, dust shields, tie rod ends, and rack ends. - Precise fit and retention: exact size and appropriate elasticity allow a secure fit on the CV joint and firm clamping on the outside of the joint without loosening. - Durable material: made from high-temperature, wear-resistant silicone to effectively protect the CV joint from damage caused by harsh external conditions. Use scenarios: - During routine maintenance or replacement on vehicles with CV joints, to protect the joint from contamination. - In suspension or steering repairs, for use with CV joints, ball joints, tie rod ends, or rack ends to guard against dirt ingress. - For off-road, dusty, sandy, or wet environments such as agricultural or construction equipment, providing reliable protection for exposed joints.
