This is an Ultra Heavy Duty replacement Engine Crossmember for the K-Series Squarebody '73-'87 GM Trucks (thru '91 for the SUV's). It features a full replacement of the factory crossmember and the side "triangles" that your motor mounts bolt to (yes, this means you have to lift and support the engine to install this - but we feel that little extra effort is worth the additional strength!) It bolts into some of the rivet holes, and there are a few more holes that will need to be drilled. There is a drop-out center section for oil pan access, and there are also track bar tabs for installing a track bar when changing to crossover steering. **This crossmember will also clear LS Engine oil pans :)
Don't forget that we can also supply H.D Motor mounts (both stock replacement and LS swap styles) along with this crossmember!
This item is "Make to Order", and can take anywhere from 2-5 days to fabricate before shipping!
