Axial SCX10 Shock Seals
Purpose
These replacement spacers are designed to address oil leakage issues in factory Axial SCX10 shocks. By replacing the original 1mm spacers with these 1.4mm versions, the additional thickness provides extra compression on the O-rings when the bottom cap is tightened, creating a tighter seal without affecting damping behavior.
Practical Uses
This modification is intended for RC crawler enthusiasts looking to prevent oil from escaping their SCX10 factory shocks. The increased thickness aims to provide a more reliable seal over long-term use.
Included Parts
- Shock Spacer AXI233002 replacement (.stl)
- OpenSCAD source code (.scad) for tolerance adjustments
Printing and Assembly Guidance
For printing, the creator used a Prusa MK4 with a 0.4mm nozzle and PET-G material. It is recommended to use a 0.10mm layer height to ensure a smooth perimeter. Users should print a single test piece to verify that the outer diameter matches the original injection-molded spacers and that the thickness is exactly 1.40mm. The inner diameter can be slightly smaller as long as the shock shaft glides smoothly.
To assemble, rebuild the shocks according to the manual, replacing the original spacers between the O-rings with these printed parts. Apply shock lubricant liberally around the O-rings. The bottom shock cap may feel slightly tighter than before due to the increased spacer thickness.

<h3>Axial SCX10 Shock Seals</h3><p>The SCX10 factory shocks are well known for their terrible leaking. I've tried a very simple approach at fixing this issue by replacing the spacers beween the O-rings at the shock body bottom.</p><p> </p><p>After this simple modification the shocks haven't shown any signs of leakage in over two weeks. Dampening behaviour seems unaffected.</p><p>Updates</p><ul><li>2025-01-28: 6 months later, the shocks are still perfectly fine. No more leaking for me.</li><li>2025-04-15: 9 months later, still no leaking.</li></ul><p> </p><p>The original spacer provided by Axial has 1mm thickness. These replacement spacers are 1.4mm. The idea is that the additional thickness will squeeze the o-rings just a tiny bit more when the bottom cap is screwed on which results in a tighter seal. Just enough to prevent the oil from escaping.</p><p> </p><h4>Printing tips</h4><p>At this small size tolerances of an individual printer can already make a difference. Here's what worked for me:</p><p> </p><p>Printer: Průša MK4</p><p>Nozzle: Your trusty 0.4mm nozzle is a good fit.</p><p>Material: PET-G, White is just what I had loaded at the time. :-) In hindsight it allows to easily distinguish the printed parts from the original black spacers.</p><p>Print settings: I started from the default <i>structural</i> 0.20mm printing profile as a baseline. The only change I made was to lower the layer height to 0.10mm to give the rings a smother perimeter. The result is a solid object anyway, which is what we need.</p><p>I recommend printing a single one and measure the resulting object. It should have the same <i>outer</i> diameter as the original injection molded spacers. The <i>inner</i> diameter may be slightly smaller as long as the shock shaft is able to smoothly glide. Thickness of the spacer must be 1.40mm.</p><p>Once you know the size is exact, print one for each shock you want to fix.</p><p> </p><h4>Shock rebuild</h4><p>Rebuild the shocks as described in the manual. Replacing the original spacers between the O-rings with these printed ones as you go. Apply shock lubricant liberally around the O-rings.</p><p>The bottom shock cap should go on just fine, maybe a tad tighter than before, but this just shows that the sealing should be better now.</p><p> </p><h5>OpenSCAD source</h5><p>The sourcecode for OpenSCAD is provided, so you can adjust tolerances to fit your printer if need be. Yes, the model is coded quite lazily, I admit that. </p><p> </p><h5>Please report back!</h5><p>Have you tried this shock-mod? Did it fix the shock leaking on your crawler? Please comment below!</p>
