Product Description

QA1 5.0L Tubular K-Member
Dramatically reduce weight on the front of your 1979-1993 Mustang 5.0 with this QA1 tubular K-member! QA1's redesigned K-member is over 50% lighter than your factory K-member, coming in at only 25 pounds! Eliminating this much weight will greatly reduce track times and while stiffening up your front end! To go along with the weight savings, QA1's tubular K-member will also improve suspension geometry as well as provide an optimized control arm and steering rack mounting location. All of this is achieved while retaining the factory wheel base!

QA1 Quality
QA1 designed this K-member to reduce weight, improve header & oil pan clearance, as well as suspension geometry. All of this was completed and built with the highest quality, American-made HSLA steel right here in the USA! By digitally indexing a new, factory K-member; QA1's tubular K-member is a direct bolt-on installation. Their removable engine mounts will support your pushrod 5.0 engine, but can easily be changed out for future engine swaps! This will be the last K-member you have to buy!

Fitment Note
-Coilover suspension is required with this kit.
-While factory control arms will work, QA1 control arms are recommended for best results.

Should have done research on the k-member before buying. Purchased on advice from local speed shop. The form posts about the engine not lining up with engine brackets are true. Same with driver side wheel rub issues. Engine is 1 inch forward and off center by about a .25 inch causing the driver side tire to significantly rub with 245/45 17s. Had to install short throw shifter to shift into 1,3,5 and put on a pair of 205/45 17s up front for minimal rub. The k-member has no more adjustment on the driver side to move k-member back. Contacted qa1, they were not helpful. Sad they had never heard of the issue though can find quite a few posts with a quick Google search. Passenger side was fine. Should have gone with the maximum motor sports k-member.
