TLR Silicone Shock Oil 35WT (420 cSt) — 4 oz RC Car/Truck Fluid

Product description

Team Losi Racing TLR74024 silicone shock oil is a 100% silicone damping fluid intended for radio-controlled electric cars and trucks. This SKU is a 35 weight (commonly listed as 420 cSt) formulation supplied in a 4-ounce plastic bottle.

The fluid is designed to fill standard RC shock absorbers to control compression and rebound characteristics. Being silicone-based, it resists foaming and maintains viscosity over a range of temperatures, helping deliver consistent performance during runs.

Use the oil to tune handling by swapping viscosities — thicker fluids slow piston movement for firmer suspension, while thinner fluids allow quicker response. The bottle contains enough fluid for multiple shock services and is color-coded for easy identification when switching between viscosities.

Pros

  • Stable silicone formulation
  • Generous 4 oz supply
  • Color makes identification easy

Cons

  • No precise measurement markings on bottle
  • Cap can drip if not handled carefully
  • Basic packaging without spout adapter

VerdictThis 35WT (420 cSt) silicone shock oil from Team Losi Racing comes in a 4 oz bottle and provides predictable, repeatable damping for electric cars and trucks. It’s useful for firming or softening suspension responses depending on the setup, and the volume supplied covers multiple shock rebuilds. While the bottle gives a clear supply and color cues help identification, users should be prepared for

    Stiffens suspension well

    Added it to my Stampede 2WD VXL to firm the suspension; reduced roll and improved control in turns.

    Plenty of fluid

    Large amount in the bottle and the oil performs as expected.
