Learn how to replace the rear bumper on your HP141 or HP141S RC truck with this step-by-step guide. Includes tips on removing the old bumper and installing the new spare part.

Quick answer

To replace the rear bumper on your HP141 RC truck, remove the old bumper by unscrewing the mounting screws, then align and secure the new BEZGAR rear bumper spare part (part number 14110C) in place.

Why you might need to replace the rear bumper

The rear bumper on an RC truck takes a lot of abuse during jumps, crashes, and rough terrain. Over time, it can crack, break, or wear out, leaving the chassis and rear components exposed to damage. Replacing it with a genuine spare part ensures proper fit and protection.

Choosing the correct replacement part

The HP141 and HP141S models share the same rear bumper design. Using an original spare part like the BEZGAR Rear Bumper (14110C) guarantees 100% compatibility. Avoid generic bumpers that may not align with the mounting holes or provide the same level of protection.

Step-by-step replacement guide

1. Remove the old bumper: Use a small Phillips screwdriver to remove the screws securing the old rear bumper to the chassis. Keep the screws in a safe place. If the bumper is broken, be careful not to damage the surrounding plastic. Check that all screws are removed before pulling the bumper away to avoid stripping the threads.
2. Clean the mounting area: Wipe the mounting area on the chassis with a dry cloth to remove dirt, debris, or broken plastic pieces. A clean surface helps the new bumper sit flush and prevents misalignment. Inspect the chassis for cracks near the mounting holes; repair or replace damaged parts before installing the new bumper.
3. Align the new bumper: Position the BEZGAR Rear Bumper (14110C) so that its mounting holes line up with the holes on the chassis. The bumper should sit evenly and not be tilted. If the holes do not align, do not force the bumper—it may be the wrong part or the chassis may be bent.
4. Secure the bumper: Insert the screws through the bumper into the chassis and tighten them gently with a screwdriver. Avoid overtightening, which can strip the plastic threads or crack the bumper. Use thread-locking compound (blue, medium strength) on the screws to prevent them from loosening during use.
5. Test the fit: Once installed, gently press on the bumper to ensure it is firmly attached. Check that it does not interfere with the rear wheels or suspension movement. If the bumper rubs against the tires, loosen the screws slightly and adjust the position before retightening.
