Challenger CLHM90 Transmission Jack Adapter — Exhaust Clearance for CLHMHTJ-1000

Clear the Exhaust, Reach the Transmission

The Challenger CLHM90 is a purpose-built adapter for the CLHMHTJ-1000 hi-rise transmission jack that solves a common problem: exhaust components that run too close to the transmission for the standard saddle to fit. On vehicles like those equipped with the 4L80E and 4T80E transmissions, the exhaust crossover or downpipe passes directly alongside the transmission pan, blocking standard jack saddle contact. The CLHM90 extends and offsets the contact point so you can support the transmission securely without removing the exhaust first.

Save Time on Every R&R

Without the CLHM90, shops typically spend 30 to 45 minutes removing and reinstalling exhaust components just to get the transmission jack in position. This adapter eliminates that step entirely on supported applications, turning a multi-step removal process into a direct jack-and-pull operation. The adapter mounts securely to the CLHMHTJ-1000 saddle and maintains the jack's full tilt and rotation capabilities.
