Traxxas Silicone Shock Oil 60wt (700cSt)
The shock oil crawler builders recommend as the starting weight. Traxxas 60 weight, around 700 centistokes, is the heavy viscosity forums point to for most crawlers: it slows rebound so the suspension settles and stays planted on rock instead of bouncing you off line. The silicone formula is consistent and widely stocked, and 60 weight is the safe default that suits a typical crawler before you fine-tune. For controlled crawling it is the reliable, do-first pick.
View on Amazon Editorial illustration.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.
How do the best options for shock oil for an RC crawler compare?
| Pick | Product | Why it makes the list |
|---|---|---|
| Top pick | Traxxas Silicone Shock Oil 60wt (700cSt) | The shock oil crawler builders recommend as the starting weight. |
| Thicker | Traxxas Silicone Shock Oil 80wt (1000cSt) | A thicker 1000 centistoke oil for maximum damping and slow droop on heavier or competition rigs. Step up to this if your crawler is heavy or still bounces on 60 weight and you want the suspension even more deliberate. |
| 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. |
What should you look for in shock oil for an RC crawler?
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 |
