Ingalls 93037 - Manual (Page 2)

Step 4: Align Stiffy™ Engine Torque Damper Bracket (with Ingalls logo) over the passenger side strut tower bar rear
mounting point and the inner most strut top stud. Place the supplied thin spacer on the other mounting point for the
strut tower bar and reinstall with the OE strut tower brace on top of the Stiffy™ bracket. Torque hardware to OE
specifications, or to no more than 20 ft-lbs. Also reinstall any aftermarket strut tower braces and the two remaining
passenger side strut top nuts. (See Figure 1, Arrows A)
Step 5: Align and install the remaining Stiffy™ ETD bracket over the factory engine mount. While installing place OE
cross brace through the hole in the bracket in the same orientation as it was removed. Install hardware for the cross
brace and then torque to OE specifications; no more than 15 ft-lbs. (See Figure 2, Arrow B) Reinstall engine mount
hardware and torque to OE specifications (65-70ft-lbs), check to ensure that Stiffy™ bracket is flush with mount
surface. (See Figure 3, Arrows C)
Step 6: Adjust Stiffy™ Engine Torque Damper to the desired stiffness (see www.ingallseng.com for preload
adjustment procedure) and then adjust the length to match the two mounting points on the Stiffy™ brackets. The
mounting points are approximately 7 inches center-to-center, therefore the Stiffy™ will need to measure the same
distance. (See Figures 1 and 3, Arrows D)
Step 7: Install Stiffy™ ETD using supplied hardware in the following order; Bolt, Stiffy™ end-link, o-ring, bracket,
washer, lock nut. This orientation is crucial for the reduction of ancillary vibrations. (See Figures 1 and 3, Arrows D)
(See Figure 4 for complete install image)

Notes:
Proper use and fitment of the rubber O-ring helps dampen additional road noise or “feel” that can be transferred through the damper
assembly. The O-ring should be used between the Stiffy ™ heim joint and bracket for optimal noise suppression. Dynamat or other
damping materials, as used in aftermarket audio and in-car electronics industries, can also be used to provide further noise and
vibration damping when used between the brackets and the surface they mount on.
DO NOT attempt to adjust Stiffy ™ from its pre-set stiffness without consulting the Ingalls website. Large open-end wrenches are
required to adjust stiffness (27mm). Most standard and mechanics tool kits do not include these types of wrenches.
