FP750000 750K Diff Oil

Designed for fine-tuning drivetrain feel and traction balance, this silicone differential oil provides a medium-thick viscosity that sits in the “tuning sweet spot” for many RC setups. With a 750,000cst (750K) rating, it significantly reduces diff unloading while still allowing a controlled amount of differential action compared to ultra-thick 1M+ fluids. This makes it a popular choice for center or rear differentials where you want strong forward drive without fully locking the drivetrain. The 75ml bottle gives enough fluid for multiple rebuilds, making it practical for racers dialing in consistent handling performance.

• 750,000cst viscosity for balanced “almost locked” differential feel
• Helps reduce wheel spin and diff unloading under power
• Works well in center or rear diffs depending on setup goals
• Improves forward drive and stability on high-grip surfaces
• Silicone-based formula for consistent performance across conditions
• 75ml bottle supports multiple differential rebuilds
• Popular tuning step between 500K and 1M diff oils
