Ingalls Stiffy ™ Engine Torque Damper For 1994-2001 Acura Integra
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.

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. Under the hood, locate the driver’s side upper strut mount and remove the forward most 12mm strut mount nut,
located near the front upper control arm mounting bolt and nut plate. Install the Chassis Mounting Bracket onto
the upper strut tower as shown in Illustration 1. Secure bracket using the OEM 12mm nut removed in step 1 of
these instructions. Note: Be sure to locate the bracket in-line with the engine mount, since the bracket bolts in
single shear. You may have to loosen and rotate the Chassis Mounting Bracket once the Engine Mounting
Bracket is installed. To ease installation, you may want to attach the Stiffy™ Engine Torque Damper onto the
Engine Mounting Bracket, as per installation step 4, before moving to step 3.
2. Locate the driver’s side engine mount and remove both 10mm engine mount nuts. Fit the Engine Mounting
Bracket onto the engine mount as shown in Illustration 2. Secure bracket using the OEM 10mm nuts removed at
the beginning of this installation step.
3. Install Stiffy™ onto the Chassis Mount Bracket and Engine Mount Bracket using the supplied hardware. 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 supplied washer (smaller washers), which mounts against 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 washer and o-ring placement should not be
changed.
