Minimize chassis flex and  increase performance capabilities on your 1982-1992 GM F-Body with boxed  style weld-in subframe connectors from UMI Performance. Subframe  connectors are a must chassis upgrade when racing and hard driving  habits are present. They greatly improve your car's handling ability  while reducing t-top squeaks, dash rattles and quarter panel flexing.  Subframe connectors essentially tie the front and rear steel subframes  together, resulting in a stiffened and strengthened chassis; allowing  better weight transfer and improved traction when launching. When  strength is a concern, square tubing has greater torsion resistance  over tubular designs. Subframes do not effect ground clearance and  weld-in style requires no bolts to tighten ever and less chance of flex  compared to bolt-in types.     Our subframe connectors for the  third generation F-Body are one of the strongest set-ups on the market.  This unique design utilizes a 3 piece design, allowing (6) major weld  points through out the chassis of the vehicle. Subframe connectors fit hard top, T-Top and convertible models.
