{"product_id":"transmission-crossmember-49","title":"Transmission Crossmember","description":"The G Force RCGNG-400KBLK is a Next Gen transmission crossmember engineered for 1978-1983 GM G-Body vehicles, including models like Malibu, Monte Carlo, El Camino, Cutlass, Grand Prix, Regal, Century, LeMans, Caballero, and Bonneville. This crossmember is specifically designed for compatibility with TH400 and 2004R transmissions. It features a newly designed and manufactured construction by G Force Performance, aimed at providing a lighter weight for enhanced performance while maintaining the quality of the original RCG-400K crossmember.\n\nThis product includes a frame extension, FE-100, which is pre-packaged with the crossmember to duplicate the longer frame required on earlier generation vehicles. G Force recommends using a polyurethane transmission mount, such as their GMTM, which is sold separately. The crossmember has a black powder-coated finish and includes all necessary mounting hardware.\n\nInstallation notes specify that for all 78-83 G-Body crossmembers, the passenger side hump is taller than the driver's side. It's also noted that this generation of vehicle can experience body bushing compression, potentially requiring replacement of body bushings if floor pan clearance is insufficient for installation. Some users have reported success in gently lifting the floor pan with a floor jack and wood cushion to create the necessary clearance. The crossmember is installed with the exhaust clearance humps closed on top and open on the bottom. Additionally, on some installations, it may be necessary to remove the catalytic converter heat shield from the passenger side floor pan.","brand":"GForce","offers":[{"title":"Default Title","offer_id":52872727363896,"sku":"RCGNG-400KBLK","price":410.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/transmission-crossmember-49","provider":"MOTORMIA","version":"1.0","type":"link"}
