The "Stiffy"
A self-contained elastomeric shock
that mounts on brackets between the engine and the chassis. It reduces extreme
engine movement and dampens the motion, providing many benefits. The “Stiffy”
was originally intended for the sport compact market, but can be used for some
Hot Rod*
applications if it is applied correctly.
Benefits:
-
Greatly improved off-the-line
acceleration
-
Reduced wheel hop
-
Improved vehicle stability
-
Reduced shock loads on
driveline components
-
Smoother shifting
-
Reduced wear on exhaust system
joints
-
Less vibration transmission to
the driver compared to polyurethane motor mounts.
-
Less shock load, compared to
torque straps and chains.
-
Drifting – helps reduce shock
loads when wheels gain traction.
-
Reduces motor movement –
decreases the chance of motor parts rubbing against the hood and frame.
Specs: Overall length (mount to
mount) = 7 inches (+/-1/4 inch adjustment), Mounting hole size = 10 mm (.3937 …
approx. 3/8 inch), Maximum stroke = +/-3/8 inch (no preload), Preload adjustment
= 0 – 3/16 inch (max stroke = +/- ¼ inch at max preload), Maximum shock load
(momentary) = 2000 lbs., Maximum continuous load = 500 lbs., High quality
hardened steel reinforced Teflon Heim joints, Body: 6061-T6 Aluminum, Finish:
clear silver anodize, Maximum Recommended HP = 500 with Energy Suspension or
Solid Mounts.
*Many
of these applications pull up on the drivers side motor mount (see diagram).
Chains and torque straps are used to limit motion. The chain is not a good
solution, the engine moves freely and then stops suddenly when the chain is
extended. This can cause high shock loads and broken motor blocks.
Because there are so many
different motor/chassis combinations and high amounts of horsepower, it is
important to correctly apply this product to prevent premature failure. The ETD
should be used as a “helper”, not the primary means of limiting motor movement.
Mounting brackets should be heavy gauge to limit flex and prevent harmonic
resonance. Before the ETD is installed, cable or string should be placed
between the mounting points to measure the maximum deflection. If the total
travel exceeds ¾ inch, alternative mounting solutions may be needed to avoid
damage (use multiple torque dampers, move the bracket mounts closer to the motor
pivot axis, use stiffer motor mounts, etc.).
