American Powertrain’s Hydramax Kit for Mopar A833s


It’s no secret that American Powertrain (APT) offers 5 and 6 speed transmission swaps for many popular classic Mopars. These swaps are made possible with their  Hydramax hydraulic clutch setup. Although the Hydramax system plays a huge role in their 5 and 6-speed swaps, they offer the Hydramax system for the classic 23 and 18 spline A833 4-speeds too.

APT’s Hydramax system includes everything you will need to operate an A833 4-speed from the pedal to the clutch. Its never been easier to switch out that old mechanical linkage and get into a hydraulic setup. Their patent pending firewall bracket allows for the master cylinder and linkage to be placed at the perfect angle for smooth operation. Paired with the remote reservoir makes for a very compact design.

The Hydramax throwout bearing comes pre-bled, pressure tested and uses double Buna-N for long term reliability. It works much like a brake caliper pressing on the fingers of the pressure plate when pressure is applied. This gives immediate pedal response and excellant feel. The bearing is a universal design and makes future upgrades to a 5 or 6 speed even easier.

The Hydramax system is universal fit and can be swapped into any vehicle looking to use an A833. We have APT’s Hydramax setup in Orange Crush and love it. The pedal feedback is like a new car and doesn’t give us a leg workout every time we drive. If you have a A833 and want to get rid of that bulky linkage give American Powertrain a call today. Remember they have you covered for any 5 or 6-speed needs too.
