Shock & Diff Oil

This new range of oils has been rigorously tested and developed over the last 12 months by some of Europe's leading drivers. Testing has been conducted in conditions ranging from the heat of Spain to the rain of the UK to provide the best levels of consistency possible. The drivers involved all commented that they have never come across oils that offer as much consistency and progression through the range as these new Fastrax oils. The vast range of options enabled them to tune their cars for all conditions and the easy pour lid makes changing oil the work of a moment rather than a chore.

If you are looking to make the winners circle, then choose Fastrax oils.

CORE RC high grade 100% pure silicone oil for shocks and gear diffs.

RRP FOR THESE PRODUCTS ARE £3.99-£5.99

FOR ALL CARS/BUGGIES/TRUCKS

The best shock oil weight depends on your car’s weight, whether the vehicle is 2WD or 4WD, and the terrain you drive on. 

General RC Shock Oil Weight Recommendations

Generally, the heavier the RC car, the higher the WT or CST oil is required for the shock absorbers.

TYPICAL SHOCK OIL CST 100~1000CST / DIFFERENTIALS 1000~500,000CST

- Available in a large range of viscosities from the lightest 100CST shock oil to the heaviest 500,000 CST diff oil.

- Extremely temperature resistant in both warm and cold conditions.

- Fully sealed bottles for best transport without leakage, and super easy to use lid for easy precise pouring.

- Large capacity 60ml bottle for less trips to the shops!

Effects of Differential Oil Adjustments:

Front Differential:

Using thinner oil:

• Increases steering into corners (off-power)
• If oil is too thin the steering may become inconsistent, especially it can lose forward traction (and steering) during acceleration out of corners

Using thicker oil:

• Increases stability into corners during braking
• Increases steering on-power at corner exit

Center Differential (IF HAS CENTER DIFF):

Using thinner oil:

• Front wheels unload more during acceleration
• Easier to drive on rough tracks
• If a high-power engine is used you could waste too much power and sometime “cook” the oil in the center differential because it “overloads”
• More off-power steering

Using thicker oil:

• Better acceleration
• Increases on-power steering (reduces understeer)
• Better suited on high-bite, smooth tracks
• Too thick oil gives more over steer

Rear Differential:

Using thinner oil:

• Increases cornering traction
• Increases steering into corner

Using thicker oil:

• Decreases rear traction while cornering
• Reduces wheelspin
