Ingalls Stiffy ™ Engine Torque Damper For 1997-2001 Honda Prelude
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 longer 10mm bolt, supplied in the hardware kit, into the forward front upper control arm / strut tower
mounting point. The 10mm bolt will extend out beyond the nut plate on the engine side of the strut tower. Note:
It may be necessary to move or rotate the coil spring slightly to provide clearance for the bolt. In rare cases, this
may require a spring compressor.
4. Install the Chassis Mounting Bracket on the extended bolt using the supplied spacer on the backside of the
bracket and secure using supplied nylon locking nut as shown in Illustration 1.
5. Locate the driver’s side engine mount and remove the rearward engine mount nut. Note: Do not remove the
forward engine mount nut. On the forward engine mount nut, place one or two supplied washers (as necessary
for proper fit) on top of the forward engine mount nut.
6. Install the Engine Mounting Bracket, as shown in Illustration 2, using the factory nut on the rearward mounting
point and the supplied 12mm nylon locking nut on the forward mounting point.
