Q & A

What's in the Box

Heavy duty Turbo 350 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 TH350 application.

Solid GM Transmission Mount
                        This transmission mount is made of steel and is a direct replacement for the rubber mount used on GM manual, TH-350, and Powerglide transmissions (except TH400). 

Used where typical rubber mount is likely to fail due to flexing. Must be used in conjunction with solid motor mounts.

Rubber GM Transmission Cushion

OEM-style rubber transmission cushion for many '58-'82 GM transmissions including TH350 auto, Muncie, Saginaw, and others.

  • Meets or exceeds OEM specifications 
  • Rubber formulation provides abrasion resistance and aging stability
  • Tough, hardened steel plate & inserts
  • Chemlock® bonding agent ensures superior rubber-to-metal bond
Bolt-In Crossmember Ends
                        If you don't want to weld on our engine or transmission crossmembers, use a pair of these bolt-in ends. These slip over our round tubing crossmembers and bolt to the frame.
