ROWE HIGHTEC RACING DIFFERENTIAL GEAR OIL LS 75W-140 is a fully synthetic, high-performance multi-grade gear oil engineered for the extreme demands of competition driving. Developed and proven on the track, it delivers outstanding load-carrying capacity and stays stable where standard gear oils break down.

Purpose and specifications

This oil is designed for sequential manual gearboxes and axle drives fitted with multiple-disc limited slip differentials (LS). The heavy SAE 75W-140 grade is intended for highly loaded final drives in racing cars, where shock loading and high temperatures are routine. Its friction characteristics are matched to limited slip clutch packs for chatter-free operation.

• 1L container for a complete differential or gearbox oil change
• Stable 75W-140 film from cold starts through to sustained operating temperatures around 150 C without thinning out
• Optimum protection of gear teeth, bearings and LSD clutch plates against scuffing and wear under extreme load
• Reliable shifting and power transfer during frequent load changes on the track

When to use / change?

Choose this oil for motorsport axles and sequential boxes that require a robust 75W-140 LS fluid. Under racing duty, change the oil more frequently than road use, typically every 10,000 km or once per season. It operates reliably across a wide range, roughly -30 C to +150 C. Stored sealed in a cool, dry place, shelf life is approximately 5 years.

Frequently asked questions

Is this suitable for a limited slip differential?
Yes. The LS friction package is formulated for multiple-disc limited slip differentials, preventing clutch chatter while protecting the plates.

Can I use it in a road car?
It is a dedicated motorsport gear oil. Always confirm the required SAE grade and any LSD requirement against your vehicle manual before use.

Why such a heavy 75W-140 grade?
The high-temperature viscosity maintains a strong protective film under the shock loads and heat generated in competition axles.

Suitable for: racing axles and sequential gearboxes with multiple-disc limited slip differentials. Always verify the exact approval against your vehicle's owner manual before use.
