Show original supplier description
The GForce RCAL-4L80 is a channel frame transmission crossmember engineered for 1973-1977 GM A-body models, including the Regal, LeMans, Chevelle, Cutlass, El Camino, Malibu, Monte Carlo, Century, Grand Prix, Grand Am, GTO, Vista Cruiser, and Laguna. This crossmember is designed to work with 4L80E and 4L85E transmissions. It is important to note specific fitment exclusions: this crossmember will not fit a 1973-1975 El Camino equipped with boxed frame rails, nor will it fit Laguna models with boxed frame rails. For 1973-1977 hardtop frames, the distance between the frame mounting holes for the crossmember is 51-1/8 inches; measuring your frame before ordering is crucial to ensure proper selection. A polyurethane transmission mount is recommended and sold separately.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
