Ingalls Stiffy ™ Engine Torque Damper For 1992-1995 Honda Civic / 1994-1997 Honda Del Sol
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 front upper control arm anchor bolt and remove the nut on the engine
side of the strut tower.
2. Fit Chassis Mounting Bracket over anchor bolt with the side tab directed down alongside the strut tower as
shown in Illustration 1. And secure with OEM upper control arm anchor bolt nut. Note: Make sure to press side
tab snuggly against the strut tower.
3. Locate the driver’s side engine mount and remove both 12mm nuts. Fit Engine Mounting Bracket onto the
driver’s side engine mount and secure using the OEM 12mm nuts as shown in Illustration 2. Note: The Engine
Mounting Bracket will only fit one way onto the engine mount.
4. 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.
