Description

REVOLUTIONARY GEARBOX ENHANCEMENT—CROSS-RATIO PERFORMANCE WITH STRENGTHENED GEARS.

The Unlimited Works Original 3rd–5th Gear Strengthened Gear Set represents a groundbreaking approach to Evolution gearbox tuning.

By focusing on the most demanding gears while retaining the user-friendly 1st and 2nd gears, this set delivers a cross-ratio configuration that minimizes RPM drop, particularly when shifting into 5th gear.

Constructed from materials equivalent to dog engagement gearsets, it provides exceptional strength while maintaining compatibility with stock synchromesh for everyday usability and longevity.

Product Highlights

⚙️ REVOLUTIONARY GEAR SET CONCEPT
Unlike conventional full gearset replacements, this innovative design targets the gears under highest stress during performance driving:

• 1st–2nd Gears: Retain stock gears for daily drivability

• 3rd–5th Gears: Strengthened cross-ratio gears for optimized track performance

• Result: Perfect balance of strength, usability, and cost-effectiveness

🔄 CROSS-RATIO CONFIGURATION
Optimized gear ratios minimize RPM drop between gears, keeping the engine in its power band during acceleration:

Key Benefit: Significantly reduced RPM drop when shifting into 5th gear—keeps the engine on cam and pulling hard at high speeds.

🏗️ DOG-ENGAGEMENT GRADE MATERIALS
Gears are manufactured from materials equivalent to those used in full dog engagement gear sets, providing exceptional strength to withstand high horsepower and aggressive track use. Despite the enhanced strength, the set retains compatibility with stock synchromesh for excellent feel and longevity.

🔊 STRAIGHT-CUT OR HELICAL CUT OPTIONS
Choose your preferred gear characteristic:

Straight-Cut Option:

• Maximum directness and power delivery

• Increased gear whine—characteristic “racing gearbox” sound

• Recommended for those who prioritize performance over noise

Helical-Cut Option:

• Quieter operation—minimal gear noise

• Smoother engagement characteristics

• Recommended for those who prefer refined daily driving
