Quick Change Gear Sets
Winters quick change gear sets for V8 sprint cars, used to alter final drive ratio without pulling the rear end apart. Each set is identified by a number, with ring and pinion gears sized to give a specific ratio when fitted to a Winters quick change centre section.
Most sets here use a 1" shaft with 10-spline fitment, standard across the V8 range. Picking a set comes down to the ratio you need for the track: a numerically higher set gives more torque off tight corners, while a lower set suits faster tracks where top speed matters more. Teams often carry a few sets to swap between meetings as track conditions change.
Frequently asked questions
What does a quick change gear set actually change?
It changes the final drive ratio in the rear end, which affects how much torque gets to the wheels versus top speed, without needing to rebuild the whole differential.
How do I know which gear set number I need?
The right set depends on your track length, corner speed and engine characteristics. Numerically higher sets suit tighter tracks needing more acceleration, lower sets suit tracks where higher top speed matters more.
Are these gear sets compatible with any quick change centre section?
These are sized for Winters quick change centres with a 1" shaft and 10-spline fitment, so check your centre section matches before ordering.
Why do teams carry multiple gear sets?
Because quick change gears can be swapped relatively easily, many teams keep a few different ratios on hand to match the car to different tracks or changing conditions across a season.
