A few small tuning changes can turn an average run into a podium finish—and that’s where Team Losi Racing Silicone Shock Oil 50WT (TLR74013) shines.

Why Shock Oil Matters More Than You Think

Before diving into features, let’s talk briefly about why shock oil is critical.

Shock oil controls how fast your suspension compresses and rebounds. The wrong viscosity can cause:

• Excessive chassis roll

• Poor jump landings

• Loss of traction on rough terrain

• Inconsistent handling lap after lap

50WT oil sits in the sweet spot for many setups, offering:

• Controlled damping

• Stability at speed

• Better handling on medium-to-high grip surfaces

That’s why this viscosity is so popular—and why TLR’s formula stands out.

Key Features & Benefits (Detailed Breakdown)

1. Precision 50WT (710 CST) Viscosity

One of the biggest advantages of Team Losi Racing shock oil is consistency. Unlike cheaper oils that vary bottle to bottle, TLR maintains tight viscosity tolerances.

What that means for you:

• Predictable suspension response

• Easier tuning changes

• Confidence that 50WT really is 50WT

This matters immensely when you’re fine-tuning a race setup or matching left and right shocks.

2. High-Quality Silicone Formula

This oil is made from pure silicone, not blended substitutes. Silicone oil offers:

• Excellent temperature stability

• Smooth, non-foaming performance

• Long-lasting viscosity

Whether you’re racing outdoors in summer heat or running indoor tracks, the oil maintains consistent damping characteristics.

3. Ideal Balance for Multiple Track Conditions

50WT shock oil is incredibly versatile. It works especially well for:

• Medium to high-bite dirt tracks

• Clay surfaces

• Artificial turf

• Smooth asphalt

It provides enough resistance to keep your chassis flat while still absorbing bumps effectively.

4. Perfect for Electric RC Cars and Trucks

While compatible with many platforms, this oil is particularly popular in electric RC vehicles, where smooth and predictable suspension behavior is critical.

Common applications include:

• 1/10 scale buggies

• 1/10 scale short course trucks

• 1/10 scale touring cars

• Select 1/8 scale setups (depending on shock size)

5. Trusted Team Losi Racing Engineering

Team Losi Racing is a name that carries serious weight in RC racing. Their products are developed with input from professional racers, not just hobbyists.

Buying TLR shock oil means you’re using:

• Race-proven materials

• Track-tested formulations

• A product trusted by competitive drivers worldwide

6. Compact and Convenient 2-Ounce Bottle

The 2-oz size is ideal:

• Big enough for multiple shock rebuilds

• Small enough to fit neatly in a pit bag

• No waste or drying out over time

It’s the perfect balance of value and practicality.

Real-World Performance: What to Expect

When installed correctly, TLR 50WT shock oil delivers noticeable improvements:

• Smoother landings on jumps

• Reduced chassis slap

• Improved corner stability

• Better traction through rough sections

Drivers often report that their car feels more “planted” and predictable, especially during high-speed cornering.

Pros and Cons (Honest Assessment)

Pros

✔ Consistent viscosity and high-quality silicone
✔ Excellent performance across many track conditions
✔ Trusted brand with racing pedigree
✔ Affordable price point
✔ Ideal for tuning-focused RC enthusiasts

Cons

✖ Not ideal for very low-grip or extremely rough tracks

✖ Small bottle for large-scale shock setups

Who Is This Shock Oil Best For?

Perfect Choice If You Are:

• An RC racer looking to fine-tune suspension

• A hobbyist upgrading from stock shock oil

• Running 1/10 scale electric cars or trucks

• Someone who values consistency and reliability

Maybe Not Ideal If You Are:

• Driving exclusively on ultra-rough terrain

How It Compares to Cheaper Alternatives

Budget shock oils may save a dollar or two, but they often suffer from:

• Inconsistent viscosity

• Faster breakdown

• Poor temperature stability

TLR shock oil costs slightly more, but the performance difference is noticeable, especially in competitive driving scenarios.

Tips for Getting the Best Results

• Always rebuild both shocks with the same oil at the same time
