Product image.
Shock oil is bought by weight, not brand, and for a crawler you want a heavy oil that slows the shocks down for controlled, deliberate suspension over rocks. Too thin and the rig bounces and pogos; too thick and it will not articulate. The right weight depends on your rig's mass and how technical you crawl. Look for a heavy silicone oil in the right viscosity, and match it to your crawler's weight.

A few things separate a good shock oil for an RC crawler from a frustrating one: buy by weight, heavy for crawling, match rig weight, and tune from a baseline. Weigh these before you buy.
- Buy by weight: viscosity (cSt/wt) matters more than brand.
- Heavy for crawling: a thicker oil slows rebound and keeps you planted.
- Match rig weight: heavier rigs want thicker oil.
- Tune from a baseline: start around 60 weight, then adjust.
How to choose shock oil weight
| Weight | 60wt / 700cSt (pick) | 80wt / 1000cSt | 40wt / 500cSt |
|---|---|---|---|
| Damping | Balanced, planted | Maximum, slow droop | Lighter, faster rebound |
| Best for rig | Most crawlers (baseline) | Heavy / comp rigs | Light / trail rigs |
| Feel | Controlled crawling | Very deliberate | More trail speed |
| Size | 60cc | 60cc | 60cc |

Thinner
Traxxas Silicone Shock Oil 40wt (500cSt)
A thinner 500 centistoke oil for lighter rigs or faster rebound over trail terrain, where 60 weight would feel too slow. Pick it for a light crawler or a more trail-speed feel.
View on AmazonBottom line: Traxxas 60 weight is the do-first baseline for most crawlers; step to 80 weight for heavy comp rigs and 40 weight for light trail rigs.
