Product Details

The NRG Innovations HD-400CF is a carbon fiber hood damper kit specifically designed for lightweight carbon fiber and fiberglass hoods. Engineered to replace dangerous hood props, this damper keeps the hood securely raised and stable — even under high wind conditions — reducing the risk of injury caused by an unexpected hood drop while working in the engine bay.

Built with oil-filled hydraulic shocks, the HD-400CF features both Lift-Assist and Slow-Decline functionality, giving the hood a controlled, smooth rise and a gradual, safe close. The stainless steel construction with a lightweight alloy shaft and casing and hydraulic oil-sealed end links delivers excellent durability and heat resistance in the engine bay environment. Each damper weighs approximately 200g, keeping underhood weight gain to a minimum.

The carbon fiber finish adds a premium aesthetic touch, making under-hood modifications more visually impressive for car shows and enthusiast builds alike.

Key Features:

  • Designed for carbon fiber and fiberglass (FRP) lightweight hoods — low-pressure damping tuned for reduced hood weight
  • Lift-Assist and Slow-Decline features for controlled, safe hood operation
  • Oil-filled hydraulic shocks with stainless steel construction and lightweight alloy shaft
  • Hydraulic oil-sealed end links for long-lasting durability and heat resistance
  • Approximately 200g per damper — minimal weight addition
  • Carbon fiber finish for a clean, high-performance underhood appearance
  • Thoroughly tested for repeated use and long-term reliability
  • Includes all mounting hardware for a straightforward installation

The NRG HD-400CF hood damper kit is a functional safety upgrade and a show-quality finishing touch for any enthusiast build. All necessary mounting brackets and hardware are included for a complete installation.

Found the parts I needed for my vehicle's TPMS system that I could not get anywhere else. They were a better price than any of the other online stores and got my order shipped out in a timely fashion.

Excellent business. This is my second purchase and there will be more! I ordered my parts over the holiday weekend and they mailed them the Tuesday after Labor Day. The absolute BEST pricing you will get. You will not find a lower price else ware. The shipping doesn't even take forever like most places you get great pricing. Communication is excellent, the site is very easy to use and navigate. I will be doing business with Autoplicity.com many more times and highly recommend them.

I was apprehensiveness at first to make a major purchase with Autoplicity due to their extremely low price and lack of reviews. I decided to take the chance and I am very glad I did. I made my order on a Monday morning at 0900 eastern time and my product arrived on Wednesday at 3pm. The item was exactly as described and the most astonishing part is that my purchase was released from the factory less than 45 days ago. I was expecting a model that had been sitting on a shelf for the last year and needed to be updated. That was not the case. I will definitely order from Autoplicity again in the future.

Best price I could find on the net and super fast shipping.

Great Prices and great communication. I received notification as soon as I made the order, and when it was shipped out, along with a Tracking number. They were very quick to mail it out too.<br><br>Thanks<br><br>Order number 13029

So far so good.

what an awesome site!
