Does the Nitron elec-TRON R3 fit all C7 Corvette variants?

No. This kit is only compatible with the C7 Corvette Stingray. It does not fit the Z51, Z06, Z07, Grand Sport, or ZR1.

What is the difference between the elec-TRON R1 and elec-TRON R3?

Both use Nitron's proportional solenoid valve and require either the DSC Sport V1 Controller or the Nitron DCU, but the R3 adds independent manual compression adjustment on top of the electronic damping control. That means drivers and engineers have simultaneous control over both the active and mechanical sides of the damping setup, giving the R3 a level of tunability that neither a purely electronic nor a purely mechanical kit can match on its own.

Is a controller included, and which one do I need?

No controller is included. Either the Nitron elec-TRON DSC Sport V1 Controller or the Nitron DCU is required for the system to operate; one of the two must be purchased alongside the kit. The DSC Sport V1 interfaces directly with the factory dash display and controls, offering fully user-definable calibration tables for drivers who want precise, hands-on tuning. The DCU is a standalone unit with pre-installed damping maps and a rotary control knob, better suited for drivers who want the system to handle adjustments automatically within a selected character setting.

Do the factory leaf springs need to be removed for installation?

Yes. The C7 Corvette Stingray uses a transverse composite leaf spring setup front and rear from the factory, and those are removed as part of the installation process. The elec-TRON R3 replaces the factory damping and springing setup entirely.

Can I run custom spring rates with the elec-TRON R3?

Yes. Recommended rates are available for both Fast Road Spec and Track Day Spec configurations, but custom spring rates are available on request by contacting Bulletproof Automotive directly.

Nitron elec-TRON R3 Coilover Kit for C7 Chevrolet Corvette Stingray

The Nitron elec-TRON R3 Coilover Kit for the C7 Corvette Stingray takes the elec-TRON platform a step further than the R1, combining Nitron’s proportional solenoid valve electronic damping control with independent manual compression adjustment so drivers and engineers have control over both the active and mechanical sides of the damping setup simultaneously. Each shock carries its own solenoid valve, with the elec-TRON system managed through either the Nitron elec-TRON DSC Sport V1 Controller or DCU in real time; one of the two is required for the system to operate and neither is included with the kit. Hose reservoirs are fitted front and rear, keeping independent high and low speed compression adjustment accessible at both ends alongside the electronic control, giving the elec-TRON R3 a level of tunability that neither a purely electronic nor a purely mechanical kit can match on its own. Every kit is custom built, custom sprung, and fully serviceable.

elec-TRON

Nitron’s elec-TRON system is built around a proprietary proportional solenoid valve fitted to each shock individually, giving the selected controller precise, independent damping control at every corner of the car simultaneously. Brake pressure, g-force, acceleration, steering inputs, and vehicle speed are all monitored at once, with damping adjustments made in real time. The suspension is responding to what the road and the driver are doing as it happens, not catching up after the fact.

Specialized Bi-Axis Hose Fittings

Nitron R3 hose shocks use Nitron’s own 720-degree Bi-Axis fittings exclusively; a proprietary design that makes for clean, precise installation without the compromises that come with conventional end fittings.

Standalone Electronic Damping System

The C7 Stingray elec-TRON R3 kit requires either the Nitron elec-TRON DSC Sport V1 Controller or the elec-TRON DCU to operate. Both transform the damper setup from a conventional passive system into a precision semiactive platform, continuously adjusting damping in real time based on vehicle attitude, braking forces, cornering loads, and acceleration inputs. The DSC Sport V1 and DCU differ in how they interface with the car and the level of control they offer, so the right choice depends on how the car is being used and what level of adjustability the driver wants.
- DSC Sport V1 Controller: The Nitron DSC Sport V1 Controller is a required component for the elec-TRON R3 on the C7 Corvette Stingray. It processes brake pressure, g-force, acceleration, steering inputs, and vehicle speed simultaneously, using full individual shock calibration tables to determine the correct damping level at any given moment. The result is a fully user-definable suspension platform that can be tuned with the same precision you’d apply to an engine; dialing in more mechanical grip for the track or softening the setup for daily road use.
  - Replaces factory shock controller
  - Interfaces with factory dash display and controls
  - Calculations include brake pressure, g-force, acceleration, steering, speed and full individual shock calibration tables
- DCU: The Nitron DCU is an alternative required controller for the elec-TRON R3 on the C7 Corvette Stingray. It’s the brain behind the elec-TRON system, transforming a conventional passive damper setup into a precision semiactive platform. Working in conjunction with Nitron’s elec-TRON valve, the DCU continuously processes data from the car every 5 milliseconds; assessing vehicle attitude, braking forces, cornering loads, and acceleration inputs to determine the correct valve position and damping level at any given moment. The result is a suspension system that isn’t set to a fixed damping rate but is constantly optimizing grip and comfort in real time based on what the car is actually doing. The DCU is fitted with an adjustable control knob giving the driver access to a range of pre-installed damping maps; Rain, Tour, Sport, and Race; each tuned for a specific driving context. Damping continues to be adjusted continuously within whichever map is selected, so the driver sets the overall character and the system handles the rest.

Unique Technology

Nitron starts every shock with precision components that go through a thorough design and development process long before final assembly. The modular construction gives engineers the flexibility to approach each application on its own terms, without compromising part quality or how components perform together under real load. Everything is machined to tight tolerances and inspected individually by trained technicians; that standard of quality control runs through every stage of production, not just the end of it. New materials, finishes, and processes go through extensive validation before they’re adopted, with proprietary Nitron technologies built in throughout to produce shocks that consistently hold up against the competition on road and track. That’s the engineering foundation the brand has been built on since 1998.
- Basic Damper Design:
  1. End Eye / Top Mount
  2. Damper Piston & Shim Stack
  3. Shaft / Rod
  4. Floating / Separator Piston
  5. Suspension Oil
  6. Compressed Nitrogen Gas

Bespoke Engineering

Nitron doesn’t adapt a generic damper to fit the C7 Corvette Stingray; they engineer one around it. Every application goes through a dedicated development process where components, spring rates, and damping characteristics are shaped by the specific platform, not carried over from something similar enough to work. The geometry, weight distribution, and suspension travel of the Stingray are part of the design from day one, not corrections introduced later. That’s the difference between suspension that works with a car and suspension that was purpose-built for it.

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
