We have done it again!  SRG has developed a full Independent front and rear suspension chassis for the popular 1955,1956,1957 Chevrolets that is truly and bolt in with very little, if any modifications.  We have spent many hours in design and engineering to bring this highly anticipated new chassis to you.  This is what you get:

SRG Fully sculpted frame rails, fully boxed with our exclusive inner structure truss system inside the frame which makes our frame the strongest out there when it comes to Torsional flex.  This allows the suspension to work instead of the frame flexing and robbing your car of a great ride and handle.  All factory located body mounts are in place and you can use a factory or urethane body mount kit.  Core support, bumper mounting holes are also in place.  Then we strategically place the center cross member as well as the H member in the rear for strength.  The frame is totally welded and back welded and then ground to a smooth matte finish.

Our SRG-Force Independent front suspension system is then installed and comes with all the HD Performance Monster Arm Adjustable Tubular Control Arms with all Kevlar Lined Rod ends.  Pro Spindles with Bolt On steering arms, Power Rack and Pinion Steering, Lever Type Stabilizer Bar assembly mounted in Energy Suspensions Urethane Bushings and Stainless Steel Retainers.  (Note: This chassis is also available with C4 Corvette front Suspension, C5,C6 Corvette Front Suspension or our Evolution Tubular Front suspension using C5/C6 Corvette Spindles and bearing assemblies.)

The IRS Assembly is a work of art and looks especially good when mounted under the car as is designed to fit the bottom of the Tri-Fives and isn't just a "universal" fit piece that's been adapted to this frame.  It was design exclusively for these cars.  We utilize C5/C6 Knuckles and bearing assemblies, Our Monster Arm Adjustable tubular upper and lower control arms, yes that's right.....upper control arm and we don't use the half shaft as the upper control arm.  Fully adjustable track width as well with a simple half shaft change.  Tons of adjustability built in throughout the assembly.  Lever type 1" Solid Stabilizer bar assembly with Energy Suspensions Urethane Bushings frame mounted with Adjustable ends. Kevlar lined rod ends throughout the unit.  Custom Aluminum center housing with 31 or 35 spline stub axles, High performance/horsepower half shafts.  Also your choice of gear ratio in the high performance 31 or 35 spline center section. But the most amazing part is the frame and cradle assembly that brings everything together in the most compact design that actually fits the car but does not sacrifice suspension geometry.

Comes standard with 13" Wilwood front and rear brakes with slotted and drilled E-coated rotors, 6 piston front and 4 piston rear calipers in Black, Red or polished. Has built in hidden rear emergency/parking brake as well.

Comes standard with Ride Tech RQ Billet Coilovers and Hypercoil Springs with custom spring rates for your application.  HQ and RQ Series with Remote reservoirs or Shockwave Air Ride is also available.

Comes Standard with 304 seamless stainless steel brake lines with shielded stainless flex lines out t the wheels.  Stubbed up at firewall so you can easily go from there up to your master cylinder.

Comes Standard with custom Ricks Stainless Steel 22 gallon Fuel tank for carb or fuel injection (your choice) and includes our custom bolt on tank tabs for frame mount tank.  NOTE: If you want the frame mount 22 gallon tank your spare tire well will have to be removed.

Comes Standard with 304 seamless stainless steel fuel lines from tank to firewall.

Comes with your choice of engine and transmission mount brackets.  All our engine mounting brackets are mapped and are saved in our computer system and even if your adjustable mount system doesn't allow for later desired engine or transmission changes we can go back and build you a mount system that will bolt up to what you have in most instances.

Comes with port holes for exhaust to pass through the center cross member and provisions for it to pass through the IRS as well for a clean, easy exhaust install.

Complete powder coating is available as well.

Possible modification notes:
1) For use of 22 gallon stainless steel fuel tank the spare tire well will need to be removed.
2) For track widths narrower than factory 60" wheel mount to wheel mount mini tubs or slight mods for upper ball joint clearance may be needed.
3) For Wheels wider than 9" widening of the wheel tubs may be required.
4) Some of the larger transmissions may require tunnel mods. 4L85E and TCI 6X will require trimming of the lip where foot board meets firewall.
5) Rear upper shock mount support may need to be removed on some installs.
6) Most installs on Big Blocks and LS Engines will require radiator to be moved to 6 cyl position in front of core support.
7) With wider wheel tubs installed the frame with IRS assembly will hold a 12" wide wheel easily.
