GM Auto/Man Transmission and Poly Motor Mounts, SB/BB Chevy

Transmission Mount Heavy duty polyurethane replacement for original GM mounts. Features a built-in safety lock to prevent separation. For race or street race use. Fits "most" GM transmissions having a mount on the tailshaft. The bolt spacing for the tranny mount will accomodate 3-3/4" to 4-1/4" bolt pattern on the transmission. For several applications including Powerglide, TH200, TH250, TH350, TH400, 700R4, and Saginaw, Gorg-Warner, and Muncie transmissions. Engine Mount These black polyurethane motor mounts for S/B and B/B Chevy are much stronger than OE rubber mounts but still reduce vibration. Limits unwanted movement thereby putting more power to the wheels. Tough like solid metal mounts without the vibration and noise. Resistant to oil, chemicals and road contaminants that typically deteriorate rubber.
