Team Losi Racing Silicone Diff 7000CS RC Differential Fluid - TLR5281

The Team Losi Racing TLR5281 is a 7000CS weight silicone differential fluid designed for use in RC car differentials. Differential fluid viscosity directly affects how power is distributed between wheels, and 7000CS sits on the thicker end of the spectrum, making it well suited to applications where you need a stiffer, more locked differential feel. Whether you're tuning a buggy, trucker, or short course truck, choosing the right diff fluid weight is one of the most effective handling adjustments you can make without touching the chassis.

Key Features

• 7000CS (7K) viscosity rating places this fluid in the thick range, producing a more locked differential response compared to lighter weights
• Silicone-based formula resists breakdown from heat and mechanical stress inside the differential housing
• Compatible with standard RC differential assemblies — suitable for front, centre, or rear diffs depending on your setup and desired handling balance
• Using a heavier fluid like 7000CS in the rear diff can reduce oversteer and improve traction consistency on loose or technical surfaces
• Sold as a standalone fluid, giving you the flexibility to tune each differential independently with different viscosities

What's Included

• One bottle of Team Losi Racing TLR5281 7000CS silicone differential fluid

What You Need

• Appropriate tools for opening and resealing your differential housing
• Replacement differential seals or o-rings if your diff is due a full service
• Additional TLR silicone diff fluids in lighter or heavier weights if you plan to tune multiple differentials separately
