Sneaky Horse Dual Shaft Bushing Bar is Equipped with six acceleration bushings with machined cups and two brake bushings. The lightweight design also offers better clearance than our spring bars and a strong progressive ramp in that delivers maximum torque to the tires once optimal traction has been achieved. Ideal for IMCA Crate applications with medium to high rear end mounting, or open competition (UMP/USRA/USMTS/Wissota) with low rear end mounting for maximum traction and forward drive.
