Trailing Arm Mounting Kit from A & A Manufacturing

The A & A Manufacturing stock trailing arm mounting kit (part No. KT-1B) makes removing a GM rear end from a GM Metric chassis much easier. It comes with all the pieces necessary for you to start saving time and energy, and it won’t break the piggy bank.

The company manufactures the kit’s lower trailing arm mounts (part No. LZ-13-B) from 3/16″-thick steel. They are angled to fit GM Metric chassis and have four holes for racers to adjust their trailing arm position.

“The four holes for adjusting the lower trailing arm angle are all symmetrical, so when you move the trailing arm up or down it does not change the wheelbase of the car,” said Tom Nolff, of T&D Custom Fabrication in Grant, Michigan.

The upper trailing arm mounts (part No. AA-175-B) are constructed from stout 5/8″-thick steel. Trailing arm bushings come included (part No. AA-175-C).

Shock brackets (part No. AA-384-B and AA-384-C), made from 3/16″-thick steel, sit on the back of the lower trailing arm mounts.

“This kit is affordable for most street stock racers, and it is both easy-to-install and easy-to-use,” Nolff said. “It takes less than two hours for an experienced welder to install the kit.”

The stock trailing arm mounting kit (part No. KT-1B) sells for $96.00.
