  1 1947-54 Chevrolet IFS Kit 2/1/2013 Rev0 1947-54 Chevrolet 3100 IFS Kit Congratulations on your purchase on what we believe is the finest IFS kit available for 1947-54 Chevrolet pickups with stock frames. We have invested many hours into designing a kit that will be effective, easy to install, and offer years of dependable service  –  and deliver excellent drivability. To ensure a smooth installation, please read these instructions carefully  –   don’t forget to measure twice and cut once. If you have any questions about the installation, please give us a call. Main Kit Components 1.   Lower assembly: This assembly has the IFS crossmember, frame boxing plates, and motor mounts welded as one unit. With all these components welded together, engine placement is pre-configured and the frame is strengthened where it needs to be. The  2 1947-54 Chevrolet IFS Kit 2/1/2013 Rev0 stock core support will locate the front/rear location of this assembly, which ensures the wheelbase will be within specifications. 2.   Upper Control Arm Towers: These assemblies locate the upper control arms and coilovers. A jig is provided to ensure these are accurately located on the frame. 3.   Sway bar mounting plates: These plates will weld to the bottom of the frame rail and provide threaded holes for the sway bar brackets. Installation 1.   If possible, it is advisable to start with a clean frame that has been degreased and sandblasted. 2.   Remove front shock mounts and both front and rear leaf shackle hangers (front hanger is an iron casting inside the frame rail). These items are riveted from the factory and can be removed by grinding the rivet heads or using an air hammer with a chisel attachment. The rivet shank can then be removed with a punch and hammer. 3.   The srcinal front engine mount crossmember may remain in place, however, the lower webbing that joins the crossmember to the frame rails must be removed so tab A (see figure 1) on the lower assembly box plates sits flush against the srcinal engine mount crossmember. Some frames may have a wider lower frame rail flange that must also be trimmed up to the engine crossmember as shown in figure 2. The width of the lower flange must match the upper flange, which is about 2- 1/4”.   Figure 1 - Box Plate Tabs  3 1947-54 Chevrolet IFS Kit 2/1/2013 Rev0 Figure 2 - Flange Trimming  –  View from Bottom    4 1947-54 Chevrolet IFS Kit 2/1/2013 Rev0 4.   Slide the lower assembly into place with tab A (shown in figure 1) resting against the srcinal engine mount crossmember. The top face of the 2x4 IFS crossmember flange should rest against the frame rail bottom. Please note figure 3, where the inside upper rail surface may need to be notched slightly for the boxing plates to slide in due to variances in the srcinal frame. Please note the engine mounts are tacked to the 2x4 crossmember and not the boxing plates; this allows the boxing plates to move as needed without effecting the engine mount placement.   Figure 3 - Notch inside rail as required
