FactoryOne Ultra Shock Bushings fit most 1/10th AE shocks. FactoryOne Ultra Bushings are CNC machined from an Ultra Slick material.
The stock bushing functions only as a spacer as the clearance between the stock bushing and shock shaft is excessive. Because of this excessive clearance the seals do all the work of holding the shock shaft. This lets the shaft move in a lateral direction during its stroke causing shock shaft binding, seal roll, and seal wear. The seals were never designed to function in this maner.
By installing the FactoryOne Ultra Shock Bushings, the shock shafts are correctly supported through its stroke letting the seals do what they designed to do. End result is longer seal and oil life along with consistent car handling over rough ground and when powering through a turn.
Each kit contains 2 Ultra Shock Bushings and 4 Seals
Price is $8.99 per kit (Order two kits to do front and rear)
