Chassis Engineering AT-0050B Features:

Chassis Engineering AT-0050B comes as a Bolt-on Universal Transmission Crossmember with a 0 in. drop.

Chassis Engineering Transmission Crossmember tubes are internally reinforced, heavy duty 1 3/4 in. OD tubing with a 1/8 in. wall.

We recommend using these with side engine mounts only, to avoid stressing the bell housing.

Our universal transmission crossmembers will fit most standard or automatic transmissions with rear mounting, and are available in both a Bolt-on and a Weld-on option, each available with 5 separate drops and can be cut to the width you need to fit your frame.

AT-0052B Bolt-on Transmission Crossmember with 2 in. drop
AT-0054B Bolt-on Transmission Crossmember with 4 in. drop
AT-0056B Bolt-on Transmission Crossmember with 6 in. drop
AT-0058B Bolt-on Transmission Crossmember with 8 in. drop

AT-0050W Weld-on Transmission Crossmember with 0 in. drop
AT-0052W Weld-on Transmission Crossmember with 2 in. drop
AT-0054W Weld-on Transmission Crossmember with 4 in. drop
AT-0056W Weld-on Transmission Crossmember with 6 in. drop
AT-0058W Weld-on Transmission Crossmember with 8 in. drop

However, we do have a collection of car and transmission specific crossmembers, so before going the universal route, check and see if we have one available for your setup. If we do, it will save you a bit of fabrication work.

Don't forget to include a transmission cushion with your order:

SS-0112 for 4speed, PowerGlide and Turbo 350 transmissions
SS-0114 for Turbo 400 and Turbo 700 transmissions
SS-0212 for Ford C4 transmissions

How to determine which universal transmission crossmember to use:
1. Mock up the engine mounting location using Chassis Engineering mounts.

2. Mock up the transmission placement, aiming for approximately a 2-4 degree downward angle of the tailshaft.

3. Measure from the bottom of the transmission cushion to approximately the center of the frame.

This will roughly correspond to the transmission drop. This €œdrop€ is measured from the top of the transmission crossmember tube to the top of the mounting plate.
