Description

Nitron NTR-R1 Coilover Kit for LC / LA Dodge Challenger SRT8 and R/T (narrow body)

The Nitron Challenger NTR-R1 coilover kit is built for narrow body SRT8 and R/T owners who’ve felt exactly where the factory suspension gives up, body roll that shows up before the tires do, a ride height that never quite matches the rest of the build, and a damper tuned to please everyone instead of the person who actually owns the car. LC and LA chassis Challengers run a double wishbone front end and independent five-link rear that can support a lot more precision than factory valving ever asks of it, and the Nitron Challenger NTR-R1 kit is built around that geometry specifically rather than adapted from a shelf part. Two-way combined compression and rebound adjustment lets an SRT8 or R/T owner dial in exactly how the car reacts under braking and through a corner, and the internal reservoir design keeps everything compact enough to fit inside the factory wheel wells without external plumbing to route or protect. Every kit includes adjustable top mounts and race springs, and it’s custom built and fully serviceable.

Unique Technology

Nitron’s Challenger NTR-R1 coilover kit uses 2-way combined adjustment, compression and rebound moving together off a single dial, tuned so a narrow body SRT8 or R/T owner gets a real range between a comfortable street setting and a stiffer track setup, not dozens of clicks that don’t actually change how the car feels. Everything runs off an internal reservoir, no hose or piggyback canister needed, which keeps the kit self-contained and easier to package around the Challenger’s factory subframe and control arms.
- 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 engineers their Challenger NTR-R1 coilover kit around the LC and LA chassis and its double wishbone front and five-link rear geometry rather than starting from a generic damper and working backward. Adjustable top mounts let an SRT8 or R/T owner correct camber and set ride height precisely instead of guessing at spring perch position, and the valving is developed specifically around this platform’s weight distribution and suspension travel instead of treating adjustment as an afterthought.

In 2008, the company moved into a dedicated facility in the UK’s Motorsport Valley, adding dynamometers, 5-axis CNC machines, and 3D CAD capabilities to support both growing demand and continued product development. A second expansion came in 2023 with a new office in Murrieta, California. The team behind every Nitron product draws from deep backgrounds in machining, materials technology, hydraulics, bike engineering, and F1 racing, with many engineers bringing firsthand experience as competitive drivers and riders. That depth of knowledge across both the technical and competitive sides of motorsport shapes every product Nitron develops.

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.
