When a new racing vehicle hits the market, JConcepts strives to offer a replacement and high-performance shell for competition needs. The RC8B4 is the latest platform by Team Associated for 1/8th nitro buggy racing and with it came several new features to design around for the team from Groveland, Florida. The team at JConcepts spent considerable time evaluating the new chassis layout and how to incorporate the championship winning S15 body to the vehicle.


The S15 blends performance features from the popular Silencer body with new features such as mid-body winglets and rear stabilizer kick-up. The roof of the body remains strong with the upper fin in position for stability and tracking ability. Since the latest chassis platform included revised steering geometry, front gearbox updates and a new front shock tower, revisions were needed around the entire front-end to fit the new buggy body properly.


The front and rear body mount area is cleanly designed and allows for a drop-fit on the Team Associated RC8B4 model. The S15 concept uses heavily chamfered side-pods blended into winglets made popular by JConcepts heritage designs. A standard front nose cone is included for the front of the buggy which can remain clear or painted to match. Each S15 body receives window mask, decal sheet and is backed with JConcepts customer support and racing heritage.


The success of the S15 body revolves around a commitment to off-road racing. The JConcepts team builds, tests, and travels the world to support the brand and gather valuable driver feedback in search of the best appearing and performance items on the market. The product is built, formed, and printed in the U.S.A. and always backed by JConcepts customer service, supported, and developed by professionals with style and authenticity. Look for reputable dealers and distributors and demand authentic and licensed products – choose JConcepts.

About the Silencer body design –


The Silencer body line from JConcepts is the gold standard when it comes to 1/8th off-road buggy performance. Originally crafted for the 2012 IFMAR World Championships in Buenos Aires, Argentina, the Silencer has undergone routine changes throughout the years without sacrificing performance or reliability. Over the years, the S1, as it is named, has been made available for the latest cars from Team Associated, Mugen, TLR, Tekno, and HB Racing.


In the hands of Ryan Maifield, the Silencer body is a champion at the toughest event in the world, The Dirt Nitro Challenge, and the largest event in the world, the Psycho Nitro Blast. The Silencer is a back-to-back-to-back IFMAR World Champion utilized by David Ronnefalk (2016), Davide Ongaro (2018) and Davide Ongaro (2022). Rest assured, the Silencer body has the credentials of a champion and the team support to back it up.
