Why does the elec-TRON R3 use piggyback reservoirs at the front and hose reservoirs at the rear?

It comes down to packaging. The C8's mid-engine layout creates different space constraints at each end of the car, and Nitron specifies the reservoir configuration that works best for each rather than forcing a uniform setup. Piggyback reservoirs at the front keep things compact where space is tighter, while hose reservoirs at the rear allow more flexible positioning without compromising access to the adjustment circuits.

Is the Nitron DCU included, and is it required?

The Nitron DCU is not included but is required for the system to operate. It 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. Without it, the elec-TRON shocks cannot function as intended.

My C8 was optioned with the factory front axle lift. Which kit do I need?

This kit does not integrate with the factory front axle lift system. Nitron offers two dedicated variants for C8s equipped with the factory FAL; the OEM FAL Integration variant retains the factory system after installation, and the Standalone FAL variant replaces it with Nitron's own front axle lift setup. If your C8 came with the factory FAL, either of those is the correct route.

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.

Nitron elec-TRON R3 Coilover Kit for C8 Chevrolet Corvette Stingray / Z06

The Nitron elec-TRON R3 Coilover Kit for the C8 Corvette Stingray and Z06 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 the Nitron DCU in real time; the DCU is required for the system to operate and is sold separately. Piggyback reservoirs are fitted at the front and hose reservoirs at the 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. Installation removes the factory leaf springs entirely. 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 Nitron DCU 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.

Standalone Electronic Damping System

The Nitron DCU is required for the elec-TRON R3 on the C8 Corvette Stingray and Z06 and is sold separately. 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.

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.

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 C8 Corvette Stingray and Z06; they engineer one around each platform. Every application goes through a dedicated development process where components, spring rates, and damping characteristics are shaped by the specific variant, not carried over from something similar enough to work. The geometry, weight distribution, and suspension travel of each car 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.

Notes

Factory leaf springs are removed for installation
This kit requires the Nitron elec-TRON DCU to operate; it can be purchased separately if desired
This kit does not integrate with Front Axle Lift systems. Nitron offers two additional variants for C8’s optioned with the factory front axle lift. The OEM FAL Integration variant is built to work directly with the factory system, retaining it after installation. The Standalone FAL variant replaces the factory system entirely with Nitron’s own front axle lift setup. If your C8 came with the factory FAL, either of those variants is the correct route rather than this kit.
Custom spring rates also available, please contact us directly here for more information or for a consultation on custom rates

Frequently Asked Questions

What is the difference between the elec-TRON R1 and the elec-TRON R3? Both use Nitron’s proportional solenoid valve and require 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, with separate high and low speed compression circuits that can be dialed in independently alongside the continuous electronic adjustment. It’s a level of tunability that neither a purely electronic nor a purely mechanical kit can match on its own.

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.

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.
