Ingalls Stiffy ™ Engine Torque Damper For 2005-2006 Cobalt SS
The Stiffy™ Adjustable Engine Torque Damper is engineered to reduce deflection under hard acceleration
and cornering for improved performance and power to weight transfer. Deflection in the motor mounts, as with the
chassis and suspension, is a formidable enemy in power and weight transfer, robbing valuable horsepower and
control. The innovative, built-in damper eliminates the huge amounts of “torque shock” that result from wheel-hop
and once installed; transfers more power to the road and improves acceleration, shifting, overall control and balance.
The adjustable feature allows the assembly to be tuned and pre-loaded for racing and street applications.
CAUTION: Observe proper safety and repair procedures for installation of all chassis parts. Some chassis parts require specialized tools and experience and
therefore MUST be installed by a qualified technician otherwise an unsafe vehicle and/or personal injury could result. Wear safety glasses and other protection.
WARNING: Before beginning, check for any damaged or loose suspension connections. Loose connections here indicate worn or broken parts which MUST
BE REPLACED. Failure to replace a damaged or worn spindle and/or link may cause the wheel to separate from the vehicle, possibly resulting in serious
personal injury. Installer MUST check for proper clearance. Modification(s) may be required. Please proceed ONLY if the vehicle owner is completely aware of
these potential suspension modifications.
Estimated Installation Time: One Hour
Technical Rating: Easy
Kit
Includes: Tools Required:
(1) Stiffy™ Engine Torque Damper Metric and/or SAE Socket Set
(1) Engine Mounting Bracket Metric and/or SAE Open/Closed Wrench Set
(1) Chassis Mounting Bracket Metric and/or SAE Hex/Allen Wrench Set
(1) Hardware Kit Floor Jack and Jack Stands
Installation:
1. Locate the passenger’s side engine mount as shown in Illustration 1 and remove the two outer engine mount
bolts, but be sure to leave the center bolt in place. Note: Removing all three bolts will cause the engine to drop
away from the mount and could cause damage to the other mounts or engine. Place the torque damper engine
mounting bracket onto the engine mount and secure using the OEM bolts removed at the beginning of the step.
Refer to illustration 1.
2. Locate the passenger’s side engine chassis mount, next to the passenger’s side engine mount referred to in step
1. Remove both bolts that secure the mount to the chassis, place the chassis Mounting Bracket over the mount
studs and secure using the OEM nuts removed at the beginning of this step. Refer to Illustration 2.
3. Install Stiffy™ onto the Chassis Mount Bracket and Engine Mount Bracket using the supplied hardware, but DO
NOT use the washers supplied in the kit on the Cobalt application. You may need to loosen the jam nut with an
open-end wrench and adjustable wrench to increase the assembly length depending upon application. The
supplied 15mm bolt should go through the engine side of the bracket, and the Stiffy ™ should mount on the
chassis side of the bracket. The supplied rubber o-ring is placed between the Stiffy™ rod end and the bracket as
shown in Illustration 3. The Stiffy™ nuts are black in color, where all other supplied nuts are silver in color. The
Stiffy ™ adjustment dials should be facing toward the Chassis Mounting Bracket. Note: Install bolts with bolt
head on the rod end side of the assembly and the locking nut (black in color) on the bracket side of the
assembly. Refer to illustration 3 for proper assembly of the mounting hardware. The nut and bolt can be
swapped with the nut against the bracket or rod-end depending upon application, but the o-ring placement
should not be changed. Illustration 4 represents the final installed product.
