Top Benefits – Optimised for Shift Precision and Drivetrain Survival

• Silky Gear Engagement – Delivers smooth, clean shifts under pressure

• Extreme Load Protection – Guards gears, bearings, and LSDs from wear and scuffing

• Heat-Resistant Film Strength – Maintains viscosity under race-level temps

• Limited-Slip Tuned – Friction-balanced for LSD chatter control & smooth torque transfer

• Driveline Longevity – Reduces micro-welds, pitting, and heat-fatigue damage

• Proven Under Pressure – Trusted by tuners, mechanics, and race teams alike

Race-Ready by Design – Not by Accident

KCK RE58 Pro-Shift 70W90 is a full synthetic, PAO-based manual gearbox oil designed for vehicles that demand absolute drivetrain reliability. Engineered to withstand high shock loads, extreme heat, and the torque spikes of modern performance engines, RE58 delivers precision shifts and bulletproof protection for gearboxes, transaxles, and limited-slip differentials.

Unlike conventional gear oils, KCK RE58 is hot-blended, a process that thermally activates anti-scuff, EP (Extreme Pressure), and friction modifiers during production. This ensures full additive activation from the first drive, providing consistent protection across a wide operating temperature range — from cold morning launches to punishing race heat cycles.

Ideal For:

• High-performance street & track manual gearboxes

• HSV, FPV, and other high-output RWD drivetrains

• Limited-slip differential (LSD) applications

• Motorsport builds and transaxle-equipped vehicles

• Manual gearboxes under extreme thermal and torque load

What Sets RE58 Apart?

At its core, RE58 uses Polyalphaolefin (PAO) base oils, which are superior to conventional mineral and Group III synthetics in both thermal resistance and shear stability. Combined with a highly stable additive system, RE58 resists viscosity breakdown, sludging, and oxidation — even when exposed to intense pressure and prolonged heat soak.

The formulation also includes advanced friction modifiers tuned specifically for synchroniser performance and LSD behaviour, helping reduce shift resistance while maintaining reliable torque transfer and chatter-free LSD engagement.
