Step 2: Locate passenger’s side engine mount and remove both M12 (FIGURE 1 - Arrows “B”) bolts from the engine 
mount. Fit Engine Mounting Bracket onto the passenger’s side engine mount and secure using the OEM M12 bolts. 
The longer bolt goes to the rear of the vehicle. 
 
Step 3: Begin on the Chassis bracket and install Stiffy™ onto the Chassis Mount Bracket. The supplied M10 (17mm 
HEX) bolt should go through the Stiffy™, O-ring, washer and down through the bracket with the nut underneath. The 
supplied rubber o-ring is placed between the Stiffy™ rod end and the supplied washer (smaller washers), which 
mounts against the bracket (FIGURE 3). Next using the remaining hardware mount the Stiffy™ to the Engine Mount 
Bracket. You may need to loosen the jam nut with an open-end wrench (17mm) and adjustable wrench to increase 
the assembly length depending upon application. The Stiffy™ nuts (15mm HEX) are black in color, where all other 
supplied nuts are silver in color. The Stiffy ™ adjustment dials should be facing toward the Engine Mounting Bracket. 
 
 
 
FIGURE 3
FIGURE 4
 
FIGURE 4 shows how the Stiffy™ should look after installation. The brackets should be aligned so that the Stiffy™ is 
parallel to the front of the engine. If need be, you can use spacers or washers to ensure that the Stiffy™ will be 
properly aligned. Make sure however that the rubber o-ring is against the heim joint for noise suppression. 
 
ALL BRAKE LINES MUST HAVE ADEQUATE CLEARANCE TO THE STIFFY
™ AND THE MOUNTING BRACKETS
AFTER INSTALLATION. The brake lines can be gently bent away from the Stiffy
™ or the brackets if needed to gain
clearance. Failure to provide brake line clearance could result in brake system failure and personal injury. 
 
 
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.
