Your 4x4
If longevity, durability and endurance are what you’re after when using leaf spring suspension, you need a shackle hanger and bushing that can go the distance. Tough Dog's Urethane Shackle Bush Kit switches out rubber components with naturally chemical-resistant urethane. These bushes also respond better to greasing during operation, while retaining flexibility for ride comfort and dramatically slows down deterioration compared to its rubber counterpart.
