'60-'72 Chevy Trucks - Chevy C10 Chassis - Ultimate Rails

Part One: The Main Chassis
Here is the complete chassis from Jim Meyer Racing Products. It's made to be a direct replacement for your stock undercarriage and is made up from 0.120-wall tubing.

1. For strength, Jim has added J-tubes from the bottom of the crossmember to the framerails. The pedestal-style engine supports are for GM engines; however, Jim Meyer Racing will build any engine and transmission mounts required.

2. The transmission frame brackets feature the holes for all the most popular GM and aftermarket transmissions: GM Turbo 350 and 400, 700R4, Powerglide, GM four-speed, and GM six-speed.

3. At the front of the chassis, the optional rounded framehorns will accept stock bumper brackets.

4. The company includes bed and body mounts in their stock locations on all of the chassis, as shown in this photo.

Part Two: The Suspension
1-2. Notice the upper coilover shock mount. This upper bracket can be moved about 3 to 4 inches for the stance you like best; it all happens behind the upper bracket. Two 1/2-inch Allen bolts secure the bracket to the upper A-arm tower. The bracket can also be flipped over for another 1 inch of movement.

3. The company uses the '67-'72 Chevelle spindle with bolt-on steering arms, rotors, and calipers. If you want a 5-on-5 wheel pattern, you'll have to go to the GM 12-inch disc brakes from a '77-'88 Impala/Caprice. Looking into the back of the spindles reveals the beefy, 1-inch-thick bolt-on steering arms that replace the stock front steering arms. The ball joints are easy-to-get GM items used from about '74-'88 on most midsize and fullsize GM cars.

4. This chassis features the optional power Mustang rack that bolts in the same mounts as the standard manual rack. You can also see how the optional sway bar is attached to the rails via the bracket and urethane bushings. The same IFS shown on the chassis is also available separately as a weld-in kit.

Part Three: The Rearend
1. Out back, you get either a mandrel or fabricated 2x4 box-tube step over the rear. Jim Meyer Racing also builds a new custom-width 9-inch housing with alloy axles for your chassis. The 24-inch-long, adjustable, four-link bars attached to the outside of the rails make for an exhaust-friendly chassis. Different steps over the rear suspension are available up to 10 inches. The big step will require a newly shaped bed floor that goes over the rails (inset).

2-3. There are two different styles of rear lower mounts: coilover shock mounts or air suspension mounts. The three-hole style is a street-rod-style mount, and the multihole style is a dragracing-style mount. Again, either of these brackets will hold the coilover shock or a ShockWave-style 'bag. Both will offer you an adjustable stance at the rear.
