50mm Big Bore Steering Damper

The Dobinsons SD59-821 is a big bore steering damper engineered to significantly enhance steering control and mitigate unwanted feedback, particularly beneficial for vehicles equipped with raised suspensions, larger tires, or additional accessories. It boasts a substantial 50mm (2.0-inch) body diameter and incorporates a foam cell insert, which effectively prevents oil aeration and ensures consistent damping performance even under demanding driving conditions. Constructed with durability in mind, this steering damper features induction hardened rods for superior strength and longevity. It also utilizes Teflon piston rings to reduce friction and promote smoother operation, alongside NOK triple lip oil seals for excellent sealing capabilities and an extended service life. Designed as a direct OE replacement, the SD59-821 offers straightforward installation without the need for vehicle modifications. This steering damper is an ideal solution for drivers seeking to improve steering responsiveness and reduce driver fatigue on both on-road and off-road excursions. Its robust construction and advanced internal design contribute to a more comfortable and controlled driving experience. The specified dimensions include an 18mm rod diameter and a 32mm bore diameter. Fitment is confirmed for 1984-1985 Toyota 4Runner 4WD models, including the DLX trim. While this damper is designed as a direct OE replacement, it is always recommended to confirm fitment for your specific vehicle configuration. The product is also subject to California's Proposition 65 warning regarding potential exposure to Nickel.
