In many countries so-called "Eco-Models" are very popular. In order to be able to offer also a H.A.R.M. Chassis in this section the H.A.R.M. SR-1 Chassis has been constructed.

A favorable price was one of the most important features but quality level has been kept high in order to distinguish also this H.A.R.M. Chassis from chassis of other manufacturers. 

This goal has been reached with the robust double chassis construction as well as with a motor mount system made of alloy.  

The chassis is mainly based on the EP-1 electric chassis. It is also equipped with plastic a-arms, plastic axle shafts as well as other plastic parts. The main advantage is the compatibility with existing H.A.R.M. parts.

The SR-1 chassis is delivered with tyres already glued. The body is not included. 

The motor support of the SR-1 is also the connection between rear axle and front construction. By that stable chassis construction and high crash safety is achieved.

The front axle comes stock with stabilizer bar. Toe-out, caster and camber are adjustable. The rear axle is also equipped with stabilizer. Toe-in, toe width and camber are adjustable. The transmission bracket made of alloy guarantees stable motor mounting and heat removal.

The SR-1 is delivered completely pre-mounted. All screws are fixed with Loctite. The chassis delivered are all measured and adjusted with a basic setup. This enables the driver to get first impression and to gain experience with the new chassis right away without having problems through building or setup mistakes. First of all, of course the radio has to be build in and ride height needs to be checked. The ride height can be changed easily through adjustment of the damper springs.
