Ingalls Stiffy ™ Engine Torque Damper For 1996-2000 Honda Civic
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 OEM jacking point at the front driver’s side of the vehicle and remove the drivers’ side front wheel and
tire. Note: Make sure to use the OEM or other appropriate, strong jacking point on the vehicle otherwise
damage could occur to the rocker panel, frame rail or floor pan.
2. Remove the forward bolt on the front upper control arm. This is the bolt that goes through the front side of the
strut tower. Note: Do not remove both upper control arm bolts or you may need to re-align the vehicle due to
suspension angle changes.
3. Install the Chassis Mounting Bracket with the longer 10mm bolt, supplied in the hardware kit, into the forward
front upper control arm / strut tower mounting point. Secure using the OEM 10mm nut removed in installation
step 2 as shown in Illustration 1.
4. Locate the driver’s side engine mount and remove both 12mm engine mount nuts. Install the Engine Mounting
Bracket, as shown in Illustration 2 and secure using the 12mm OEM nuts. Note: The Engine Mounting Bracket
will only fit one way onto the engine mount.
5. 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
