	<< BACK Custom Order ’49-54 Chevy Gasser Chassis

We build your chassis to your order. We build it the way you want it, with any industry standard options. This ’51 Chevy Straight Axle Gasser chassis is a direct replacement for ’49-54 Chevy's. This beefy 2x4 box tube chassis features the optional under-floor 7-inch double diaphragm booster for the single brake pedal, 48-inch ladder bars with our adjustable stance Drag Race brackets on the rear and a 3-hole forward adjustable mounting point. Any length Ladder bars, any wheelbase, any width 9-inch rearend with 28, 31 or 35-spline Dutchman alloy axles, cores support and adjustable trans mount to fit all the popular GM and most aftermarket transmissions. The new cross-steer Vega steering box connects to Super Bell Early Ford Spindles and a 2-inch dropped Pitman arm, while the springs are rated a 2500 lbs. each. You can run the spring on top of the axle or, as shown, under the axle. Notice, our chassis features a lot of center X-member support, unlike the original chassis that had only a front and rear crossmember. The front brakes are Wilwood aluminum 4 piston calipers with 11-inch diameter rotors that will fit inside 15-inch nostalgic wheels or the Wilwood 12.19-inch diameter rotors with 4-piston calipers We have a lot of options for this chassis!

		(2) Either the Straight Axle Gasser Chassis or our IFS Chassis will fit under any stock ’51-52 Chevy bodies for a stock wheelbase. Basically, Jim will build a chassis for any wheelbase car or pickup. Jim Meyer also offers Gasser Subframes (you can install at home) for any ’37-54 Chevy or he has a modern bolt-in IFS that installs to the same stock factory holes that held the original IFS. Bumper bracket holes at both ends of the chassis are included.
		(3) The 2x4 x .120-inch wall box tube is mandrel-bent over the housing and features our thru-frame crossmember for extra strength and adjustability with our multi-hole drag race adjustable brackets on the housing. The 9-inch housing comes with new center, new axle tubes and new flanges and is jig-straightened. Just behind the shock, you can see the 3-hole adjustment end of the urethane-bushed low roll-center Panhard bar.
		(4) We add the beef to the 9-inch housing by adding support tubes between the center housing and the drag race shock brackets. This keeps the housing from twisting under heavy burnouts and full-power launches.
		(5) Here’s what the factory couldn’t give you in 1951… center crossmembers! The 2x3x.120-inch wall crossmember between the center of the rails connects to the fully adjustable trans crossmember. Notice the trans side-brackets are full of slotted holes for just about any transmission.
		(6) Even the center of the trans mount has an adjustable slip-fit connection that needs to be welded after bolting it to your favorite trans. With our adjustable trans mount, you get front-to-rear and side–to-side movement before you weld the center slip-fit trans pad in place.
		(7) All of the original body mounts have been added for a perfect fit to your body.
		(8) Any length ladder bars can be ordered, however our 48-inch bars are very popular due to the lift they provide. Notice the adjustment at the rear and the multi-hole front bracket.
		(9) Our urethane-bushed, adjustable Low Roll-Center Panhard bar is actually mounted at the rear of the housing to help eliminate body roll, instead of on top of the housing like most chassis builders do.
		(10) We provide a completely new 9-inch rearend. No used parts. We install new axle tubes, new flanges and new center housing and new Dutchman alloy axles. The new center housing even comes with a drain plug and gasket just like old times.
		(11) The 27-inch long spring (rated at 2500 lb. each) tucks inside the chassis at the rear. Notice the 1 3/4-diameter X .120-inch wall crossmember under the engine. More strength at the first 4-feet of the chassis is provided by the 1 1/4"-diameter x .120-inch wall tube core support for the radiator. The new Vega box accepts a splined steering U-joint, our optional 2 joint steering hook-up kit will get you hooked back up to a steering column. Ask about our lower steering column modification kits or replace your old column with a new tilt from Ididit or Flaming River. The straight axle is available any width and the Wilwood disc brakes are available with a Ford 5-on-4 ˝ bolt circle or Chevy 5-on-4 ľ bolt circle.
		(12) The axle cradles come unwelded, once your done setting the caster and then you weld them to the axle to keep it from rotation on the springs. The axle can be placed above or below the axle for the stance you like best.
		(13) The 2-inch diameter x .250 (1/4-inch) wall front axle, available any width, will raise the stock stance about 4 ˝-to-6-inches with the axle above the springs, as shown, and placing the axle under the spring brings it up an immediate 2-inches to about 8-inches above normal ride height. A big block or a small block will also make some weight difference too, which effects the stance. With computer-generated mandrel bends, we can provide a superior fit between the body and chassis every time.
		(14) We offer a lot of Wilwood brake options for our chassis up to 14-inch diameter rotor and multi-piston calipers. These Wilwood 4-piston calipers and 11-inch rotors are popular for 15-inch nostalgic wheels used in the Sixties. Wilwood “hats” feature either Ford or Chevy 5-lug patterns.
		(15) Under-floor pedal assembly or firewall mounted master cylinder are your option. For this chassis a 7-inch double diaphragm booster was used. Anything larger may require floor modifications. The pedal shaft (shown) will accept either a single or double pedal assembly. Notice the bushing on the shaft makes this a brake-only unit.
		(16) We give you at least 3-inches of stance adjustability at the rear with our multi-hole mounting brackets for either coilover shocks or ShockWave air springs. Both styles of brackets shown: Our 3-hole Standard Street Rod Bracket or our adjustable multi-hole Drag Racing Style Bracket will accept coliovers or ShockWaves. The Drag Racing Bracket offers more adjustment, about 4-5-inches. Both upper brackets have a fixed two-position mounting point. We would normally use this upper outer-hole for the larger diameter ShockWave air springs. Notice how we incorporate “torque struts” between the housing and the coilover shock Drag Racing style brackets. This helps to eliminate housing “wind-up” under torque loads.
