Camaro/Nova g-Machine Subframe System
Chassisworks’ muscle-car g-Machine Camaro
subframe is a direct-fit, high-performance
suspension solution designed for
classic GM F-body (1967-69
Camaro and Firebird) and X-body
(1968-72 Nova, Apollo, Omega,
and Ventura) vehicles. The system features Chassisworks’
g-Machine double A-arm, rack-and-pinion crossmember.
Its direct bolt-on design enables a time-saving, straight-
forward installation that requires absolutely no custom
fabrication. Unlike others, ours is the only subframe that
includes mounting provisions for all major vehicle system
components, as well as an optional chassis-stiffening,
subframe-connector system. As an option, factory-welded
motor-plate and mid-plate brackets can be added for vehicles
requiring maximum chassis stiffness.
True Direct-Fit NoFab
Installation
Direct-fit installation ensures that all
major drivetrain components remain
in their exact factory positions. Engine
height and setback are stock, requiring no
additional hood clearance or modification
to the firewall or transmission tunnel. Two
mounting styles of anti-roll bars are available. The standard
rear-mount anti-roll bar has the same forward clearance as
the stock Camaro clip. Optional splined-end, forward-mount
anti-roll bar attaches under the front frame rails, forward
of the rack and pinion to provide approximately two more
inches of forward pan clearance. A hub-to-hub width of
60” matches the original factory dimensions,
allowing use of preexisting or factory
wheels without the need for spacers.
Ride height is approximately 1-1/2”
to 2” below stock and maintains 4-1/2”
of ground clearance below the suspension crossmember. The
system accepts factory height (25.5”) tires, with up to an 11”
tire section width and 5” wheel backspacing. Acceptable sizes
include 275/45-16, 275/40-17, 275/35-18, 275/30-19, and
275/25-20. Note: 1967-68 Camaro fenders may limit tire
section width to 9.5”.

Subframe Body Bushings
Body-bushing kits are available for
g-Machine or stock-subframed 1967-81
Camaro/Firebirds and 1968-74 Novas; in
urethane (P/N 6822) or billet aluminum (P/N
6816). Urethane bushings have adequate
rigidity for performance street
cars, but they significantly
dampen noise and vibration
transferred into the passenger area. Billet aluminum
bushings are more suitable for road race or drag race
vehicles, where maximum rigidity is required and noise and
vibration are less of a concern.

Transmission Crossmembers for g-Machine
and OEM Subframes
To accommodate popular drivetrain combinations, direct
bolt-in, tubular transmission crossmembers are available for
g-Machine equipped or factory-subframe GM F-body (1967-
69 Camaro and Firebird) and X-body (1968-74 Nova, Apollo,
Omega, and Ventura) vehicles. Crossmembers are 1-1/4 x .120”-
wall steel, dual-tube, fully enclosed structures that are stronger
than OEM stamped designs and rigid enough for the vehicle
to benefit from stiff polyurethane transmission mounts. Tubes
are bent to provide 3” dual-exhaust clearance and to correctly
position the mount for each model transmission. Slots allow for
drivetrain-position variances such as the addition of a mid plate.
Factory-installed weld nuts eliminate accessing the hardware
from above the subframe mount, allowing the crossmember to
be positioned tightly into the stock floor channel and greatly
simplifying installation.
Direct-fit transmission crossmembers are available for Turbo
350, Turbo 400, Powerglide, 700R4, 200-4R, 4L60, 4L65E,
6070
ESP 3.1108G
6073
Muncie 4-speed, Richmond 5- or 6-speed, and many Tremec
5- or 6-speed transmissions. Crossmembers are finished in
gloss-black powder coat for a modern appearance and ship
with Grade 8 hardware. Note: Installation on factory subframe
requires additional adapter kit (6073).

4130 6-Point Camaro Roll Cage
Swing-Out Clevis Sets
Dual-purpose design makes a roll-cage side bar or back brace
fully removable — or, simply swing it out
for easy entry! In gStreet™ applications,
clevis sets are provided for the driver's
and passenger's cage-side bars, and for
the main-hoop back brace. Clevis
tube adapters match the specific ID
and OD the selected cage or roll bar. Swing-
out side bars are NHRA-accepted.
The gStreet™ Exact-Fit roll cage is intended
for street-performance applications to add a level of
protection and increase chassis rigidity. To improve interior
clearance, fit, and accessibility, cage sides and rear struts
feature additional bends not normally found in race-duty roll
cages. Full 6-point cages are available in mild steel (1-5/8 x .134"
or 1-3/4 x .125" DOM) or 4130 (1-5/8 x .083"). Quick-release
removable door bars and back brace are included. Two-styles
of cage sides are available. The standard "in-front" design is
routed around the stock dashboard. The "through" version
follows tightly along the A-pillar and passes through the top of
the dashboard, requiring modification to the sheet metal dash
structure. Removable forward support struts can also be added to
further improve chassis stiffness. These bolt directly to the upper
firewall at the fender mount, the most rigid part of the firewall,
and attach to the suspension subframe using our weld-on Gemini
connectors. Also included, but not shown is an optionally installed
1-1/4", triangulating rear strut to tie the main hoop in to the
vehicle's subframe connector.
Back-brace clevis tabs point
rearward for easier entry into
the back seat

Mild-Steel 4-Point Camaro Roll Bar
Safety Notes – gStreet™ Roll Cage/Bar
Removable Forward Support Struts
(For g-Machine or OEM Subframe)
Featuring 1-3/4 x .134", mild-steel construction and high-
clearance rear struts, our Exact-Fit 4-point roll bar is an excellent
street-car-friendly choice. Back braces are available as a weld-in
bar or, for additional seat clearance, a removable-bar version with
clevis set can be selected.
Our in-house-engineered Gemini
system is used to connect the strut to the
subframe, enabling an easy-to-assemble,
precision slip-fit joint that is substantially
stronger than a welded joint.
Adding tubular struts between
the factory upper firewall area
and subframe triangulates the
front clip, virtually eliminating
chassis deflection forward of
the firewall. Upper-strut-mount
plates bolt directly to the '67-69 Camaro firewall at the
fender mount, the most rigid part of the firewall. The lower
end of the support strut utilizes Chassisworks' exclusive
bolt-together Gemini connector system. Installation of the
strut and mounts requires minor trimming and welding for
individual fit, but can later be unbolted to facilitate regular
maintenance or subframe removal.

g-Machine Exact-Fit Roll Cage (side view)
Roll-Cage Padding
For safety purposes, padding must be applied along any areas
of the cage that occupants may come into contact with.
Not for Competitive Use
Due to the additional cage-side and rear-strut bends, and
removable door bars and back brace the g-Machine cages are
not intended for competitive motorsports. Our competition series
roll-cages are designed for ultimate strength and safety, and are
better suited for serious competitive applications.

Bolt-In Subframe Connectors
Chassisworks is the only manufacturer to incorporate a
bolt-on chassis-stiffening system into our direct-fit 1967-69
Camaro/Firebird, 1968-72 Nova subframe design.
Our unique clamping method is simple to install
and creates a connection equally as
strong as a welded connector. Once
installed the connector system provides
a direct structural bridge between the
rear subframe at the spring mount and
the g-Machine front suspension subframe.
A noticeable improvement in chassis rigidity
yields more responsive handling and sharper acceleration
while relying less on the flexible sheet metal for chassis
stiffness. The g-Machine subframe’s profile-milled, billet steel
connector mount enables a non-flexible, precision fit for the
subframe connector. The tubular connector fits snugly over
the mount, flush along the lower face, and is securely held
in place by doubling plates to more evenly distribute the

clamping force from two 1/2” Grade 8
bolts for a slip-free joint. The 2 x 2 x
.120”-wall connector tube features
multiple, subtle mandrel bends to
tightly follow the undercarriage for maximum
ground clearance and perfect alignment with the
rear factory subframe. To provide the most direct support and
increase stability, the OEM leaf-spring mount sandwiches
two of the three gusseted connector mounting tabs against
the body, while the third tab attaches using a drilled hole at
a stronger, contoured area of the undercarriage. This product
ships with a black powder-coat finish, complete with Grade
8 hardware and detailed instructions. Note: This product
can be used only with hardtop models equipped with our
g-Machine subframe system.
Inner Fender Splash Flaps
Durable rubber splash flaps are
available to take the place of
the OEM pieces. Debris within
the engine compartment is
kept to a minimum due to
the flap’s contoured edge,
specifically designed to fit
the g-Machine suspension
and OEM inner fender.
