Tiger Quick Change — Quick Change Rear Ends & Gear Sets for Dirt Track & Oval Racing
Tiger Quick Change manufactures quick change rear ends, gear sets, and supporting components for dirt track, sprint car, and oval racing applications where the ability to change gear ratios rapidly between races is a competitive necessity. In oval track racing, gear ratio selection directly affects acceleration out of the corners, top speed on the straightaways, and engine RPM at the end of the longest straight — and the ability to change that ratio in minutes rather than hours is what separates a quick change rear end from a conventional differential in a racing environment.
Quick Change Rear Ends
Tiger Quick Change rear ends use a removable gear cover that allows the final drive ratio to be changed by swapping a pair of spur gears — a process that takes minutes with basic hand tools rather than the hours required to change ring and pinion gears in a conventional differential. This rapid ratio change capability allows teams to adjust their gear selection between heat races and features, or to respond to changing track conditions and race formats without the time penalty of a conventional gear change.
The quick change housing is engineered for the specific load requirements of oval track racing — sustained high-speed cornering loads, repeated acceleration and deceleration cycles, and the mechanical shock of rough track surfaces and contact. Housing construction uses high-strength aluminum and steel components with precision-machined bearing bores and gear mesh geometry that maintains correct alignment under the load conditions of competition use.
Gear Sets & Ratio Coverage
Tiger Quick Change produces a comprehensive range of spur gear sets covering the ratio range used across dirt track, asphalt oval, and sprint car applications. Gear ratios are available in fine increments to allow precise final drive ratio selection for each track configuration and class rules package. Teams typically carry multiple gear sets to cover the ratio range needed for different track sizes, surface conditions, and engine combinations encountered across a racing season.
Gear sets are manufactured from high-quality steel with correct tooth geometry and surface finish for quiet operation and long service life under racing loads. Correct gear mesh and backlash adjustment during installation is critical for gear set longevity — Tiger Quick Change provides setup specifications for each gear set to ensure correct installation.
Axles & Supporting Components
Tiger Quick Change produces axles, bearings, seals, and supporting hardware for their quick change rear end systems. Axles are available in standard and heavy-duty configurations for different power levels and class requirements, with correct spline count and flange dimensions for the Tiger housing. Bearing and seal kits provide the replacement components needed for routine maintenance and rebuild of the quick change unit over the course of a racing season.
Common Applications
Tiger Quick Change rear ends are used across dirt Late Model, dirt Modified, dirt Sprint Car, asphalt Late Model, and a range of additional oval track classes where quick change rear ends are permitted by the rulebook. Class rules vary by sanctioning body and track — verify that a quick change rear end is permitted in your specific class before purchasing. Tiger Quick Change products are used at local weekly tracks through regional and national touring series by teams who demand reliable, serviceable rear end equipment.
Build Quality & Racing Validation
Tiger Quick Change components are manufactured to the dimensional tolerances and material specifications required for sustained oval track racing use. Housing machining tolerances ensure correct bearing fit and gear mesh geometry that maintains alignment under the load and heat cycles of a full race night. Gear sets are manufactured and inspected to correct tooth profile and surface finish specifications that ensure quiet operation and correct load distribution across the full tooth contact pattern.
Installation & Maintenance Notes
Tiger Quick Change rear end installations require correct housing mounting in the chassis for proper pinion angle and axle alignment. Gear set installation requires correct backlash adjustment per Tiger's specification for each gear set — incorrect backlash causes accelerated gear wear and noise. The quick change oil should be changed regularly — gear oil in a quick change rear end is subjected to high shear rates and temperatures that degrade the oil more rapidly than a conventional differential. Inspect the gear sets for wear and correct mesh pattern at each oil change interval.
