KILLERBODY MARS KR10 – 1:10 Rally Chassis ARR

The perfect chassis for the 1:10 Lancia Stratos Gr.4 Rally Body
Body shell not included.

Rally Performance Meets Scale Appearance

With the KILLERBODY MARS KR10 ARR Chassis (Item No. 48838S), you get a high-quality, pre-assembled platform for your own 1:10 rally project. This specially developed chassis combines durable materials, precisely engineered suspension components and a powerful 4WD drivetrain – ideal for building a legendary Lancia Stratos Gr.4.

One of the key features is the rear axle, which has been specifically designed to match the wide Stratos body. With a rear width of over 201 mm, the chassis sits perfectly underneath the distinctive body and delivers an authentic scale appearance.

Thanks to the ARR version (Almost Ready to Run), most of the mechanical assembly is already completed. This means less time spent building and more time enjoying your rally car on the track.

ARR Version with Exclusive Upgrades

Compared to the standard version, the MARS KR10 ARR (48838S) comes with several high-performance upgrades already installed from the factory.

Carbon Shock Towers

Lightweight carbon shock towers at the front and rear combine excellent rigidity with low weight, providing precise suspension response.

Compact Front Bumper

The specially designed high-density polyurethane bumper is shaped to fit perfectly underneath the low front end of the Lancia Stratos body.

Less Assembly Work

The complete mechanical drivetrain and suspension are already pre-assembled, saving you valuable time during the build.

Fully Adjustable Rally Suspension

Whether you're driving on gravel, asphalt or carpet, the suspension can be precisely tuned to suit different track conditions.

Aluminium Oil-Filled Shocks

The shock bodies are made from 6061 aluminium and feature steel shock shafts. The adjustable spring preload allows precise suspension tuning and smooth, controlled damping.

Adjustable Suspension Links

Camber, toe and ride height can be precisely adjusted using the adjustable suspension links. This allows you to fine-tune the handling to suit your driving style and track surface.

Robust 4WD Drivetrain

The permanent four-wheel-drive system reliably transfers the power of your Brushed or Brushless motor to all four wheels.

The lightweight 6061-T6 aluminium centre driveshaft and a total of 20 high-quality stainless-steel ball bearings ensure a smooth-running and efficient drivetrain.

The front 6061 aluminium CVA driveshafts provide reliable power transfer even at high steering angles.
