Does the Nitron Challenger elec-TRON RoadSport coilover kit come with the controller needed to run it?

No. It is sold separately from the kit, however, it's available as a add-on for the kit. The Nitron elec-TRON DSC Sport V1 Controller is required for the system to function.

Is manual damping adjustment available on this kit?

Manual adjustment isn't required since the solenoid valve and DSC Sport V1 Controller handle damping automatically, but the compression and rebound knobs are still there for anyone who wants to set a baseline manually.

How fast does this Nitron Challenger elec-TRON RoadSport coilover kit react to changing conditions?

The solenoid valve at each corner adjusts damping every 5 milliseconds, well inside the 100 to 150 milliseconds it takes to blink.

Does this kit retain the factory top mount?

Yes. It uses the OEM top mount, which keeps noise, vibration, and harshness in check compared to an adjustable aftermarket mount.

What's the difference between this kit and the passive Nitron Challenger NTR-R1?

The NTR-R1 is a passive kit relying entirely on manual adjustment, while the elec-TRON RoadSport adds a solenoid valve and DSC Sport V1 Controller on top of shared R1 hardware for continuous automatic damping control.

Can custom spring rates be ordered?

Yes. Every kit is hand made to order, and custom spring rates beyond the standard setup are available by contacting us directly.

Description

Nitron elec-TRON RoadSport Coilover Kit for LC / LA Dodge Challenger SRT8 and R/T (narrow body)

The Nitron Challenger elec-TRON RoadSport coilover kit is built around exactly the kind of car narrow body SRT8 and R/T owners actually drive, one that gets pointed at a canyon road on a Saturday and then has to survive a Monday commute without beating up the driver’s back. Most suspension upgrades force a choice between that comfort and real capability, and this kit is built specifically to avoid that trade. It uses a proportional solenoid valve at each corner to continuously adjust damping every 5 milliseconds in response to braking, cornering, and acceleration forces, turning what would otherwise be a passive kit into a semi-active one without any input needed from the driver. Running the system requires the separately sold Nitron elec-TRON DSC Sport V1 Controller, which reads brake pressure, g-force, acceleration, steering input, and vehicle speed simultaneously and uses individual shock calibration tables to set the right damping level in real time. The kit keeps the factory OEM top mount, so noise, vibration, and harshness stay in check on the LC and LA chassis and its double wishbone front and five-link rear while handling improves noticeably over stock. The hardware shares its core technology with Nitron’s Challenger NTR-R1 coilover kit, so there’s real engineering underneath the comfort-focused brief, not just a softer tune.

elec-TRON

Each shock in Nitron’s Challenger elec-TRON RoadSport coilover kit carries its own proprietary proportional solenoid valve, giving the system precise, independent damping control at every corner at the same time. It reads g-load, vehicle speed, road surface, and driver input all at once, making damping corrections every 5 milliseconds. A blink of the human eye takes somewhere between 100 and 150 milliseconds, so the suspension isn’t estimating what the road is doing, it’s responding to it in real time, corner by corner.

Standalone Electronic Damping System

The Nitron elec-TRON DSC Sport V1 Controller is a required component for this kit and is sold separately. It processes brake pressure, g-force, acceleration, steering input, and vehicle speed simultaneously, using full individual shock calibration tables to determine the correct damping level at any given moment. The result is a suspension platform an SRT8 or R/T owner can tune with the same precision they’d apply to an engine, dialing in more mechanical grip for a track day or backing off for a long highway drive.
- 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

Unique Technology

Nitron builds every shock in the Challenger elec-TRON RoadSport coilover kit from precision components that go through a rigorous design and development process before final assembly. Modular construction gives Nitron’s engineers the flexibility to work through this platform properly instead of cutting corners on how parts are made or how they perform together under real load. Everything is machined to tight tolerances and checked individually by trained technicians, and that quality control runs through the whole process rather than sitting at the end of it.
- 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 didn’t start with a generic damper and reverse engineer a fit for the LC and LA Challenger. This kit was developed from scratch around the SRT8 and R/T platform, with components and damping characteristics built for its double wishbone front and five-link rear rather than adapted from something in the same ballpark. Geometry, weight distribution, and suspension travel were factored into the Nitron Challenger elec-TRON RoadSport kit’s design from the beginning, not addressed as an afterthought.

Additional Information

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.

Shipping Policy

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.

BP Pricing Difference

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.
