1954 Chevy BelAir owned by Deb Meyer equipped with our adjustible stance Bolt-In IFS Kit
37-54 Chevy Car Bolt In Front Steer



With the new Jim Meyer adjustable-stance independent front suspension, you can adjust it up-or-down about 4-inches for the stance you like best. We are the only company in the industry to offer an adjustable-stance IFS. See our home page for a complete section on how we designed the adjustable front-and-rear suspension. We also have a few photos (in this section) that show where and how the IFS is adjustable. Just keep scrolling down through this section. The photo of the ‘54 shown (above) is in the lowest adjustable position. Drop spindles are another option that will bring it down 2-inches more. You can go to our installation instructions from the home page and see if you can install this IFS at home. Just minimal tools are required and a weekend to do the work is necessary. Once the crossmember is located, using existing holes in the frame, a few new holes will need to be drilled using the crossmember as a template. The upper shock/A-arm towers have tabs that will need to be welded on. If you do not have a welder it is possible to drive the car, once everything else is done, to someone who can do the welding for you.

Our bolt-in IFS, as you’ll see in the following photos, is totally compatible with the original engine/transmission. It fits around all stock components and requires the steering column to be modified at the bottom end. Click here to see how to modify your lower steering column.

The IFS kit features a 2 X 4 X .188-inch wall box-tube crossmember that holds the D.O.M. 1-inch diameter X .156-inch wall lower tubular A-arms and 7/8-inch diameter X .156-inch wall upper tubular A-arms. Steering is provided by a new manual rack-and-pinion, while two ’67-72 Chevelle spindles, ball joints, 11-inch rotors, and calipers give you stock over-the-counter GM parts available most everywhere! With a two-position lower mount and a three-position upper mount, the aluminum, adjustable coilover-shocks will give the stance you like best!

With 15-inch wheels and 215/60R15 tires, it measures about 23-inches from the ground to the top of the fender opening as shown

The bumper is about 10-inches from the ground.

The bolt-in kit is a direct replacement using the same original factory holes that held the original GM suspension to the chassis. Nearly Identical frames were used from 1937-48 and ’49-54. As you can see, the fully assembled IFS with antisway bar can be rolled under the car and the old one out of the car on a floor jack. The entire IFS can be assembled on the bench and then rolled under the car and is held in place with the same 10 bolts that held this ’53 IFS. Since we use ’67-72 Chevelle spindles, we offer a lot of brake options including the Wilwood 4-piston calipers and 11-inch or 12.9-inch rotors, or Chevelle 11-inch disc brake system and more. Power steering and our 1-inch diameter antisway bar and adjustable coilover shocks offer more options. We offer either optional adjustable or standard non-adjustable coilover shocks. The optional adjustables are available with either external single-adjustable rebound damping only or external double-adjustable bump-and-rebound shock damping, or optional spring rates from 180-850 lbs.

Not only was this original '54 Chevy IFS used in '49-54 Chevy cars, but it was also used in the '53-62 Corvettes, so sell it. It has king pins and bushings and will wander all over the road if everything isn't new. Notice the frame mounting-pads are identical to the new IFS pads. No welding or cutting necessary to remove it, just hand tools.

Looking at the inside of the driver’s side chassis, notice how the inner chassis lip has been trimmed away for extra steering-shaft clearance. Our ’37-48 IFS uses only two U-joints, while the ’49-54 IFS installation uses three-U-joints and a bearing support. Notice on the inside lip there are three bolts holding the IFS to the rails and two-bolts on the outside lip.

In this view one of the five mounting-bolts (on each frame rail) is hidden under the motor mount on the inside of the rail-lip. These are existing factory frame holes. We offer a GM motor mount and trans mount kit for this (’49-54) installation, if you are doing a 350/350 side-mount engine/trans swap at this time. The only welding on this “bolt-in” installation is the small upper-tower support tabs that are welded to the frame. Notice, just behind the upper A-arm cross-shaft there are 2 Allen-head bolts that connect the upper tower bracket to the tab welded to the frame underneath it. Scroll farther down (this section) and there are four photos showing you specifically this bracket and how it attaches.

The bolt-in IFS installation features ’67-72 Chevelle spindles with bolt-on steering arms. The GM balljoints are some of the most common GM items available at every parts store. One-inch diameter antisway bars (front-and-rear) and the power steering (shown here) are optional items. Notice at the top of the photo, the trans mount adapter plate for GM 350, Muncie 4-speed or PowerGlide transmissions bolts to existing holes and places the new hole pattern in the correct position from your new side-mount 350 engine and transmissions mentioned above.


IFS Kits

Just ask for the ’49-54 GM 350 engine/trans mount kit for stock chassis. You will have to weld-in the new engine mounts.

We are the only manufacturer that offers front-and-rear adjustable suspension. Almost every IFS or chassis we build has our popular adjustable stance IFS and this upper coilover shock-mount is where it happens. The upper bracket featuring two ½-inch Allen-head mounting bolts has 4-holes for a three-position movement of about 3-inches. The offset upper bracket can be flipped over for about another ¾-inch of adjustment and the two position lower A-arm mount offers about ¾- inch of adjustment by moving to the outer hole in the lower A-arm bracket.

IFS Kits

We have different length upper coilover brackets for different installations that will interchange here.

Our standard kit comes with ’67-72 Chevelle spindles (shown) with 11-inch GM rotors, calipers and our bolt-on steering arms (shown). Drilled and ball-milled rotors are optional as well as our Wilwood super stoppers that fit this GM spindle.

Our 1018 steel, ¾-inch diameter, nickel plated lower A-arm cross-shafts are some of the largest in the aftermarket industry (other IFS use ½-or-5/8-inch od shafts). For easy removal of the cross shaft from the front crossmember, we have installed bronze bushings in the crossmember holes. The shaft will never rust and the hole will never rust and be impossible to remove. We want your disassembly to be an easy one. For smooth A-arm movement, and to eliminate telescoping road vibration through the steering, we use 90-Durometer urethane bushings to isolate the lower A-arm cross shaft in the crossmember. If you'll notice in the close-up view of the bronze bushing, we have included a set-screw hole to secure the cross shaft from rotation. This way the rotation is on the urethane bushings in the A-arms and not the bronze bushings in the crossmember hole, for all those happy miles you're going to drive. The CNC machined aluminum end-caps and counter sunk flat-head 5/16 screws on each end of the lower cross shaft hold it into the crossmember. It is critical that you use Loctite on these threads, other wise the cross shafts will work their way out!
