What it is: Half-shafts for IRS.
Why you care: Jesse Powell of GForce
Engineering says it best: “In today’s
climate, we have to provide customers
a better product for their money—one
that can handle power levels never
conceived of even 10 years ago, and we
need to do this while ensuring a fair
price point. This is the first step in
elevating our offerings.” The popular
flagship product in the GForce line is
the Outlaw axle, which has received
a significant upgrade for 2019, with
polished CVs inside and out, an internal
alloy upgrade for increased strength,
and the inclusion of ARP fasteners. The
improvements make the new Outlaw
axle the strongest CV possible in abolt-in application. In addition to
the Outlaw upgrades, GForce has
replaced its 850HP (L2) axles with
the more capable Renegade axle line,
offering similar specs and benefits
of the high-end Outlaw line, but at a
lower price. GForce axles are available
for many late-model performance
vehicles from Dodge, Ford, Chevy,
and Pontiac.

What it is: Street-Trac traction bars.
Why you care: If we face the facts,
Detroit muscle cars were built for
low cost and ease of manufacturing,
not maximum traction. That’s why
Classic Performance Parts has engi-
neered some of the nicest traction
bars we’ve seen. CPP’s new Street-
Trac traction bars complement your
overworked leaf springs by firmly
planting the tire at launch, eliminat-
ing wheel hop, and lowering your e.t.
The front mount features additional
ground clearance and a forward-
slanted approach angle. In the event
it does hit something, the angled
approach will act as a skidplate and
help lift the car over the obstacle.
The portion of the linkage that
contacts the spring is a wider, flat
surface, which reduces the stress on
the top of the leaf spring. The pivot
positions are relocated to optimize
weight transfer while reducing the
spring load. Street-Trac bars are
available for 1955–1957 fullsize
Chevy, 1962–1974 Nova, 1967–
Camaro, and 1964–1973 Ford
Mustang.

What it is: Millermatic 255 and
Multimatic 255.
Why you care: Miller Electric’s Miller-
matic 255 and Multimatic 255 inverter
welders each weigh only 84 pounds,
50 percent less than the Millermatic
252 MIG welder. Because these
machines are smaller than most others
in their class, there is more room to
weld. The simple user interface on both
provides a 7-inch color LCD screen and
straightforward controls with Auto-Set
Elite technology, which allows the
operator to set the weld parameters by
selecting wire and gas type, wire diame-
ter, and material thickness. Changing
tasks is fast and easy with programma-
ble memory settings, while Auto-Line
technology allows for any single-phase
input voltage hookup (208–240 volts
for the Millermatic 255 and 208–volts for the Multimatic 255) with no
manual linking. The Millermatic 255
MIG welder is built for professionals in
the light manufacturing or fabrication
segments who are looking for a smaller,
more versatile machine (metals up to(^1) ⁄ 2 -inch thick with an output rating of
230 amps and 25.5 volts at a 60 per-
cent duty cycle). The Multimatic 255
multi-process welder delivers MIG, but
adds stick, DC Lift-Arc TIG, pulsed MIG,
and higher voltage capability.

What it is: Self-learning EFI system.
Why you care: Edelbrock’s Pro-Flo 4 EFI
does not require laptop tuning. The key
to this user-friendly system is Edel-
brock’s exclusive E-Tuner 4 application,
which uses self-learning capability to
continually adjust the calibration to get
the maximum performance out of an
engine. A Bluetooth wireless connection
communicates with the ECU, giving
users the ability to monitor engine vitals
and adjust both fuel and spark from the
E-Tuner 4 app. Complete control of
air/fuel ratios, ignition curve, idle speed,
acceleration fuel, coolant
fans, rev-limiter, and
more is programmable
through a 7-inch
Android tablet with
the E-Tuner 4
app preinstalled. For
users with an existing
Android-based smart-
phone or tablet, the E-Tuner 4 app
can be downloaded for free in the
Google Play store. Pro-Flo 4 EFI is avail-
able for popular Chevrolet, Ford, Chrysler,
and Pontiac applications with several
configurations to meet horsepower needs.
