Team Losi Racing Silicone Diff 500000CS RC Differential Fluid - TLR75009

Team Losi Racing's TLR75009 Silicone Diff Fluid is a 500,000 weight (500k cS) differential oil formulated for use in RC car differentials where maximum resistance and locking characteristics are needed. At 500k viscosity, this is one of the thicker weights in the TLR silicone fluid range, making it suited to centre or rear differentials in high-powered buggies and truggies where drivers want a near-locked diff feel without fully sealing the unit. Silicone-based diff fluid does not absorb moisture, holds its viscosity more consistently than petroleum-based alternatives, and won't damage rubber o-rings or seals inside the differential housing.

Key Features

• 500,000 cS (500k) viscosity rating — one of the thicker weights available, producing a near-locked differential response
• Silicone-based formula resists moisture absorption and maintains consistent viscosity across a range of running temperatures
• Safe for use with rubber o-rings and seals inside differential housings — won't degrade internal components
• Allows precise tuning of diff feel when used alongside lighter weights; swapping fluid weight is one of the most effective setup changes in competitive RC
• Compatible with most 1/8 and 1/10 scale off-road RC differentials that use silicone fluid

What's Included

• One bottle of Team Losi Racing TLR75009 Silicone Diff Fluid — 500,000 cS weight

What You Need

• RC vehicle with a rebuildable differential that accepts silicone fluid
• Appropriate tools for opening and resealing your differential (typically hex drivers and o-ring picks)
• Clean workspace and lint-free cloths for differential servicing
