Plastic stops for suspension

NSR Precision Replacement to Keep Your Suspension Always on Point

The NSR1207 plastic suspension bump stops are the original replacement part specifically designed for the suspension system of the NSR 1249 chassis, used in the Mosler Evo3. Their function is to limit and control the suspension travel, ensuring that the car's geometry remains within the correct parameters both in club racing and competition configurations.

Function and Performance

The suspension bump stop is a small but critical component in the dynamic behaviour of the slot car. It acts as a physical limit to the suspension travel, preventing the chassis from operating out of range and ensuring that the guide maintains contact with the rail during elevation changes or high-speed corners.

• Controls the maximum suspension travel.
• Contributes to the stability of the guide over the rail.
• Prevents premature wear of other suspension components.
• Manufactured from precision plastic according to original NSR specifications.

Compatibility

These bump stops are designed for the NSR 1249 chassis and their direct application is the Mosler Evo3 model. If you have questions about compatibility with other NSR chassis versions, we recommend consulting us before placing your order.

Installation and Preparation

Replacing the suspension bump stops is a straightforward operation that does not require special tools. Nevertheless, it is advisable to pay attention to the following points:

• Check the condition of the other suspension elements before installing the new bump stops.
• Ensure that the bump stop is correctly seated in its position without forcing the plastic.
• Once installed, verify the suspension travel by gently pushing the car body on the bench to confirm it operates freely and within range.

Common Mistakes

One of the most common mistakes is to overlook the condition of the suspension bump stops during routine maintenance. A worn or broken bump stop can cause erratic behaviour of the car, especially on tracks with pronounced elevation changes, and can easily be mistaken for issues with the motor, tyres, or guide. If your Mosler Evo3 exhibits inexplicable instability, checking these bump stops is a good starting point.
