Ingalls Engineering "Stiffy" Scion tC 2004-Up A self-contained elastomeric shock that mounts on brackets between the engine and the chassis. It reduces extreme engine movement and dampens the motion, providing many benefits. The “Stiffy” was originally intended for the sport compact market, but can be used for some Hot Rod applications if it is applied correctly. Benefits Greatly improved off-the-line acceleration Reduced wheel hop Improved vehicle stability Reduced shock loads on driveline components Smoother shifting Reduced wear on exhaust system joints Less vibration transmission to the driver compared to polyurethane motor mounts. Less shock load, compared to torque straps and chains. Drifting – helps reduce shock loads when wheels gain traction. Reduces motor movement – decreases the chance of motor parts rubbing against the hood and frame. Specifications Overall length (mount to mount) = 7 inches (+/-1/4 inch adjustment) Mounting hole size = 10 mm (.3937 … approx. 3/8 inch) Maximum stroke = +/-3/8 inch (no preload) Preload adjustment = 0 – 3/16 inch (max stroke = +/- ¼ inch at max preload) Maximum shock load (momentary) = 2000 lbs. Maximum continuous load = 500 lbs. High quality hardened steel reinforced Teflon Heim joints Body: 6061-T6 Aluminum Finish: clear silver anodize Maximum Recommended HP = 500 with Energy Suspension or Solid Mounts
