The Speedtech subframe is an affordable direct replacement for your factory worn out old subframe. Speedtech Performance's subframe offers the benefits of: Rack and pinion rear mount steering, built in Guldstrand Mod (this gives additional negative camber), coil over shock compatible, adjustable transmission crossmember and more. You can reuse all your current aftermarket suspension components such as control arms and sway bar, brakes and wheels. For maximum handling and performance, upgrade to Speedtech's High Clearance tubular control arm set to hold up to a P275 tire on a 10'' wheel. The subframe accepts small and big block Chevy's using the stock oil pan and also accepts the GM LS series engines using most after market oil pan and motor mount adaptors.
