Performance Eng Quick Change

Performance Eng Quick Change gears are premium 10-spline quick change gear sets. They are made for circle track and oval track racing, where being able to change gear ratios quickly helps you adapt to changing track conditions. Alternate names for these parts include QC gears, quick change gear sets and quick change rear end gears.

Key Features:

• Hobbed, fully heat-treated 8620 alloy steel construction for strength and longevity
• Lightweight drilled design reduces rotating weight
• REM ISF micro-finish reduces friction and heat for smoother running and longer life
• 10-spline design is intended for full-size quick change rear ends from brands such as Winters, Frankland, Bulldog (DMI), Tiger, Halibrand, Jones and PEM
• Several ratio options in the line, so you can tune for your track and setup

These gear sets are built to handle the torque of late models, modifieds, sprint cars and similar race cars. They come from Performance Engineering & Manufacturing (PEM), a maker of racing drivetrain components.
