Our tail housing kits are our mechanical speedometer kits: one family of parts, not two. The 4L60E and 4L80E were built for electronic speedometers, so they have no cable drive. These kits add one, so your LS swap keeps a factory mechanical speedometer and the original gauge, with VSS retained. Running a 6 bolt 700R4? The 6 bolt to 4 bolt adapter lets it take a stock 4 bolt tail housing.

Before you order: get the gears right
Speedometer gears are cut to the tooth count for your tire diameter and rear gear ratio. Run the speedometer gear calculator first, or read the formula, worked out, then bring the tooth count to checkout. Between sizes, or running an odd rear gear? Call and we will cut it to suit.
Want the background? Read why the 4L60E and 4L80E have no speedometer cable and how a speedometer drive works. Choosing a transmission? See 4L60E vs 4L80E for an LS swap and which transmission goes with each LS engine.
