Dear Welder Series…
I’m building a 1930 Model A on boxed ’30 frame. I want to use your flat crossmember in order to use a 1936 wishbone with the spring forward of the axle.
I want to know if I can place your flat crossmember in front of the stock cross member in order that I may keep the original design, i.e. radiator and fenders etc…??
Has anyone done this before??
I want the car as low as possible and the use of the intact ’36 wishbone. I intend on using cross rack steering and need the clearance as well.
Thanks,
Mike
Dear Mike…
Thanks for looking at Welder Series’ parts.
Our flat front crossmember is designed for a 1-3/4″ wide spring, like the 1928-34 Ford. The ’36 Ford used a 2″ wide front spring, so it will not fit in our crossmember. The ’36 spring is longer than the Model ‘A’ spring, so it can’t be adapted to the ’36 stock wishbone, either.
The ’36 axle will be a little wide to let you get the front end low. (The tires will be out at the edge of the fenders.) You might want to mock up your parts to see how it looks before buying any parts. The standard way to get a Model ‘A’ low is to use a 46″ dropped axle with a reversed eye spring with a low arch.
I hope this helps.

Dear Welder Series…
Thanks Paul…….I already have the 31″ 1 3/4 reverse eye spring with a 6″ arc, now I need the 46″ axle. I wanted to use the 1936 wishbone unsplit but I guess I will have to split it after all.
Thanks again,
Mike
Dear Mike…
Mike, you might be able to use the wishbone unsplit and just cut off the spring perch extensions. The spring would mount above the axle.
Paul
Dear Welder Series…
YES, that’s what I intend on doing I just have to find the widest perch possible on the “I” beam. The wishbone is 39.5″ apart and the “I” beam I have is 36″ and I have a feeling that the 46″ axle will also have around 36″ between bosses. Maybe I can bend the wishbone to match the bosses when I get the 46″ axle.
Worse scenario is splitting the wishbone…………..
Since I have you online, do you guys sell “X” crossmember for the model A frame? I need something for my 4L60 transmission to bolt onto. I’m running a 283 cu. in. motor as well and will also need the motor mounts to weld to the frame and attach to the motor, side mounts.
I have a 1930 model A frame that is completely stepped up and boxed. I have a center cross member but I would like to reinforce the frame a little more and have the setup to bolt on the brake pedal, etc..
Thanks again,
Mike
Dear Mike…
Mike, most 46″ axle perch centers are about 34-1/2″. You should be able to bring the wishbone in to match the 46″ axle perches. Make sure the ball stays in the center.
We don’t have a Model ‘A’ x-member. Check Dagel’s https://dagels.com/super-x-crossmember-kit/. Welder Series does have Chev motor mounts.
GM Triangulated Rear 4-Link Suspension Kit
Designed with the tried-and-true triangulated 4-link configuration used by GM for decades, this rear suspension kit provides enhanced stability and eliminates the need for a Panhard bar. Its adaptable design accommodates various frame widths, making it a versatile choice for custom builds and restorations.
High-Quality Construction and Design
- Bars: Constructed from 1″ heavy-wall seamless tubing, each bar is tapped at one end with a 3/4-16 thread and precision-notched for the urethane bushing tube on the other. The upper bars measure approximately 18" center-to-center, while the lower bars span about 25" center-to-center. This setup ensures strong support and effective articulation.
- Frame Brackets: CNC-formed from 10-gauge pickled & oiled mild steel, the upper frame brackets are robust and can be trimmed for a perfect fit across a range of frame widths. The lower frame brackets feature a 3/16" thick section for frame welding, providing extra durability where it’s needed most.
- Axle Brackets and Tabs: Made from 3/16" pickled & oiled mild steel, the axle brackets and upper axle tabs are engineered to withstand the demands of high-performance applications.
Adjustable Coil-Over Mounting
This kit offers three mounting positions for coil-overs on the axle brackets, allowing for flexible ride height adjustment and suspension tuning. For those preferring to install coil-overs later, consider our adjustable ride height setup tool, which temporarily replaces coil-overs during the build phase. This tool preserves coil-over integrity and provides clearance checks for components like the exhaust and driveshaft through suspension travel.
Premium Energy Suspension Bushings
All bracketry is matched to the outer diameter of Energy Suspension urethane bushings (1-3/4" wide, 1-5/8" OD), which deliver excellent vibration dampening and add a clean, streamlined appearance upon assembly. The kit includes 3/4-16 threaded adjusters to fine-tune suspension alignment for a tailored fit to your build’s specifications.
Welded vs. Ready-to-Weld Kits
- Welded Kit: In the welded option, all parts that can be pre-welded by our team are assembled, including the lower frame brackets, bars, adjusters, and the coil-over support block within the axle brackets.
- Ready-to-Weld Kit: This option is fully customizable, arriving unwelded for those who prefer control over the final assembly, especially in adjusting the bar bracket angle to the front frame bracket.
Additional Options and Accessories
For builds requiring 3-1/4" axle tube brackets, these are available as an add-on. Check our related products for additional accessories to complete your setup.
Kit Specifications:
- Model: 318500 (available in both welded and ready-to-weld)
- Bushings: 1-3/4" wide, 1-5/8" OD Energy Suspension urethane bushings
- Adjusters: 3/4-16 threaded
Shipping and Ordering Information
This kit ships via UPS to the lower 48 States and 10 Provinces with a transparent shipping cost structure of $54–$59 (10% of the order total + $10; minimum $15, maximum $75). No additional duty or brokerage fees are applied, and tracking information will be provided upon shipment.
Complete installation instructions are included to support a smooth, straightforward installation, making this kit a strong, customizable solution for GM triangulated rear 4-link setups.
