Quick Answer
Replacing worn shock absorbers on your BEZGAR HM181 or HS181 restores handling and prevents chassis damage. Use the genuine PX9300-01 pair for a direct fit.
Why Replace Shock Absorbers?
Worn shocks cause bouncing, poor traction, and uneven tire wear. On RC cars like the HM181 and HS181, damaged dampers can lead to bottoming out on jumps, stressing other suspension parts. Replacing them restores predictable handling and protects the chassis.
Step-by-Step Replacement
- Remove the Old Shocks: Place the car on a flat surface. Use a screwdriver to remove the screws securing the top and bottom of each shock absorber to the chassis and suspension arm. Gently pull the shock free. Common mistake: Forgetting which end is top or bottom—note the orientation before removal.
- Compare New and Old Shocks: Hold the new PX9300-01 shock next to the old one. Verify the length, spring rate, and mounting hole alignment match. If they differ, the replacement may be for a different model. Common mistake: Assuming all shocks are interchangeable—check part numbers. If the new shock is longer or shorter, stop and confirm compatibility with your HM181 or HS181.
- Install the New Shocks: Position the new shock in the same orientation as the old one. Insert and tighten the mounting screws at the top (chassis side) first, then the bottom (arm side). Do not overtighten—snug is enough to avoid stripping plastic threads. Common mistake: Tightening the bottom screw first, which can misalign the shock. After installation, press down on the car’s body and release. The suspension should compress and rebound smoothly without sticking.
