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.
