It's a safe bet that if you're reading Circle Track then you've had exposure to a quick change rearend, either seeing one at the track or actually racing one yourself. Quick changes are designed to enable you to quickly and easily change your rearend gears. Even a novice can swap out gears in one of these rears in under 15 minutes. But before you can start swapping gears, you need to get the rearend together and into the car. Recently, we had the opportunity to do just that. So follow along as we put together and install a new Tiger Quick Change Rear End into a Dirt Late Model.

There is still quite a bit of work to get done on this car before it is race ready, but in one relatively short evening we assembled and installed a brand new Tiger Rear End.

    Tiger's directions give a good pointer when putting together a new rearend-after you place the axletube into the left side bell, attach a hub to the axletube. Invert that assembly onto a wheel (we used one mounted to an old tire) and voila! You're new rearend will be at a perfect working height.

    We wiped down the inside of the bell with a clean rag. This is a necessary step to make sure that the interior of the rear is clean. Any packing material that came loose during shipping could cause a problem down the road.

    The bearings must be oiled before the center section is fully assembled. We used Tiger's 90 weight synthetic gear oil. When we break in the rear, we'll use regular petroleum based gear oil as directed by Tiger's instructions.

    Rotating the bearing by hand helps disperse the oil in, around, and throughout the rollers. We repeated this same procedure for the bearing on the other side.
