Seeing that this unit is adjustable, will it clear a Moroso 7-quart oil pan? My old k-member brace had to removed because of clearance issues at around the rear oil drain plug.


  • Hi, This QA1 K-Member Brace will not work with a Moroso 7 Qt. oil pan because this brace gets installed right where the stock brace, the only adjustment that is made is width for fine tuning the pre-load.

Clear long tubes Will this brace clear long tube headers on a 1990 5.0?


  • This QA1 K-Member Brace (79-93 All) is adjustable and should clear long tube headers without any issues. If for any reason you did need more clearance, you can put a small dent in your headers and this will not affect the sound or the performance of them.

Will this brace work with the QAI tubular k-member?


  • Hi, QA1 K-Member Brace will work with QA1 Tubular K-Member because the QA1 K-Member uses the all the mounting points from a stock Ford Mustang K-member.
