Adjustable and Flexible for Improved Traction and Handling. If you've modified your Ford Mustang, chances are you're going to need the GMS Weight Jacker Rear Lower Control Arms. These adjustable control arms enable you to lower or raise your ride up to two inches. That means you can adjust the arms to allow clearance for high-profile tires or set the preload for drag racing. It's also great for road race vehicles that require adjustment to ensure proper weight distribution and balance.

Professional Race Quality Construction. The GMS Weight Jacker Rear LCAs feature precision welded heavy-duty tubular steel construction. They have a black powdercoating finish that provides excellent durability and a professional racing look. They also features a heavy-duty rebuildable Heim-style bearing axle and polyurethane bushings at the chassis that smooth out your ride.

Installation. The GMS Weight Jacker Rear Lower Control Arms includes all of the required hardware and can be installed in just a couple of hours with basic hand tools.

Application. The GMS Adjustable Weight Jacker Rear Lower Control Arms are designed to fit all 1979-2004 Ford Mustangs, excluding 1999-2004 IRS Cobras.

Fitment: 1979 1980 1981 1982 1983 1984 1985 1986 1987 1988 1989 1990 1991 1992 1993 1994 1995 1996 1997 1998 1999 2000 2001 2002 2003 2004 Details

    Was not expecting such a great ride.

    Needed more wheel clearance in the rear, didn't want to replace my springs I just installed so I swapped out my old aftermarket control arms with thee adjustable ones, cranked each side up 2 notches and it was enough to clear the wheel rotation, then I took it out for a ride and MY GOODNESS. My rear was planted! Felt so firm all around driving, better then the BBK GRIP control arms I had, well I still have the upper installed just replaced the lower with these and it was night and say

    Lower control arms

    Its ok, I had to buy new bolts because the stock ones would not fit. I had to buy smaller bolts. Other than that it's a great product. Nice product...they just need to tell you you need new mounting hardware.
