There seems to be more 55-57 Chevys on the road today than in 1957! Their tall boxy shape may say "low and slow", but in reality they can be a crisp performer with the right suspension enhancements.
The Level 3 Street Challenge system adds triple adjustable ShockWaves®, dropped spindles, MUSCLEBar™ swaybars, and the AirPod® LevelPro® compressor system to put these cars right alongside any of the modern day performance cars that you care to play with.
All of these systems require NO fabrication, NO floorpan cutting, and NO welding to the body or frame. The Ridetech 4-Link is also positioned inside the framerails to allow much needed extra rear tire clearance. Don’t settle for 50 year old technology… serious performance CAN come in a box!
NOTE: The two piece frame is made from 2 pieces of metal welded together along their length. The one piece frame is made from a single piece of metal and has no weld line. (both frames have a seam on the top of the frame the two piece also has a seam on the bottom) The width of these frames is slightly different. The two piece frame measures 35-1/8” between the framerails immediately behind the bodymount in front of the rear wheel. The one piece framemeasures 33-11/16” between the framerails. This measurement is important to determine because our 4-link crossmember is placed in that position.
Features:
Front System
with strong arm upgrade
The ShockWave® mounts much like a coilover and replaces both the coil spring and the shock absorber. The Shockwave kit for the 55-57 Chevys bolts in using the existing upper shock mount. (Note: some trimming of your spring pocket may be required)
The Shockwave system for the 55-57 Chevy will lower the car from the factory ride height by 3-4" and provides the ability to go even lower when not being driven by lowering the air pressure further.
- Unequalled ride quality
- Proven patented sealing technology
- Anodized billet aluminum construction
- Eliminates tire clearance problems
To optimize the suspension for 55-57 Chevys, our ShockWave® system allows the replacement of the factory lower arm with our StrongArm lower control arm which is included in this system (this package also includes the upper control arm upgrade).
Master Series
Triple Adjustable
Shocks are the heart of every suspension system and are the key component in provide ride control to the driver. The Level 3 system includes the upgrade to our Master Series, Triple Adjustable aluminum shocks, both front and rear.
The TA shock has an impact forged aluminum body / mono-tube design with adjustable valving. Adjustability provides more options for desired driving style which includes single rebound adjustment PLUS dual stage high and low speed compression.

(upper and lower included in this package)
StrongArm tubular control arms not only improve suspension geometry and handling, they also make installation even easier. The added benefit when replacing control arms is new bushings and ball joints. No more worn out components.

The most overlooked suspension component is also one of the most important. The magic you could be missing in your suspension may be nothing more than simply adding or upgrading your swaybar. The new Musclebar sway bars were developed specifically for lowered vehicles and will greatly enhance the cornering performance of your 55-57 Chevy ( Not to mention they'll also make some vehicles safer at the speeds we travel on today's interstate highways.
"Ball Joint" style connection allows bind free operation through a extremely wide range of motion.
- 360º rotation
- 45º misalignment
Durable design will outlast traditional bushing style connectors

RideTech spindles - These economical spindles allow you to drop your ride and increase ride quality. These spindles are STEEL, the strongest ones in the industry. | ![]() |
Billet Tie Rod Adjusters - Strong, easy to adjust and look cool too. Large wrench flats on both ends provide an easy way to dial your suspension anodized aluminum finish provides long lasting good looks. |
Rear System


The Bolt-on 4-link from Ridetech, formally known as the Airbar, is a 4-link rear suspension that will directly bolt into the oem leafspring mounts of your prized musclecar... no cutting, no fabrication, just 4 small tabs to weld to the axle for your upper bars. The ride height of your car is typically lowered by approximately 2". The ride quality and performance is dramatically improved over stock... instead of a wallowing soft ride you’ll experience a crisp, controlled ride quality that will inspire more confidence for performance driving.
- The Ridetech 4-Link system lowers vehicle ride height and provides the ability to go even lower when not being driven by lowering the air pressure further.
- Pre-engineered mounting hardware to maintain ground clearance, driveline angles, tire clearance and load capacities
- Bolt-on installation (no fabrication required)
- Greatly improved handling performance
- Ultimate ride quality.

Compressor / Control System

We have equipped our 55-57 Chevy Level 3 package with our Airpod e3 compressor system outfitted with 2 compressors and a 5 gallon tank, and includes level sensors for increased accuracy.
The Airpod e3 system features:
| 3 ride height presets with optional "Ride height on start" feature. | LevelPro Sensors monitor both air pressure and ride height to eliminate crossloading. |
| Transflective display uses sunlight to illuminate…the brighter the sun, the brighter the display. | Mini USB connectors on bottom and back of control panel offer several mounting options. |
| Waterproof ECU allows mounting anywhere on vehicle. | Compatible with existing RidePro and other brands of solenoid valves. |
| Built in troubleshooting menus provide error codes to alert users of any malfunctions. | Solid state internal compressor relays eliminate external compressor relays and wiring. |
| Waterproof threaded M12 wiring harness connectors. |
