Problem Solving Hot Rod Chassis Parts Since 1978
Mar 14 update: 36" and 45" bars are now available to be pinned both ends (no splined end). The hardware package will include two smooth ID, CNC drilled couplers and three 1/4" roll pins (two for the bar and one for you to lose under your toolbox), along with a quality 1/4" split point jobber drill. The roll pins are strong and secure but can be removed using a punch and hammer. Pins have been used on one end of our sway bars for over 10 years with zero failures. They provide a significant cost benefit over splining. We still have a limited number of 45" bars splined both ends.
Available 36″ and 45″ wide, but can be cut down (with a hack saw) to any length. The bar is ¾” diameter 4142 heat treated, cold finished. Both ends get securely drilled/pinned (drill included) with a 1/4" rolled spring pin and/or welded (optional) into a coupler which welds to the arms. The laser-cut, 3/8″ thick arms are 8″, 12" or 17” center-to-center. Urethane bushings isolate the sway bar inside the outer tube, or you can use pillow block bearings to hold the bar under the frame. Adjustable rod ends connect the arms to the tabs that weld to the rear end or frame. Overall length is ¾” longer than the bar length, since the 3/8″ arms mount outside the ends of the bar. The arms can be bent to clear the coil-overs or for front tire clearance.
How To Order:Please select from the following options when building your sway bar kit, and starting at the top of the "Add-On" list to the right, check off the various options you'd like. The base price is for the couplers, rod ends, and hardware only.
If you'd rather order over the phone, please call us toll free at 1-888-648-2150. We can walk you through the various options. Online sway bar orders are reviewed, and if we see something that looks off, we'll contact you about it.
First, choose the length of sway bar you require. You'll have to select the outer tube separately. Work your way down the list, selecting how you want to mount the outer tube and arms.
Hardware PackageThis is the basic hardware package that comes with every kit. For the heavy tube option, larger bushings will be substituted. For the "splined both ends" kits, two splined couplers will be included. Rod ends are PTFE lined, made in the USA. Bushings now come with the tube option instead of the hardware package.
Sway Bar Mounting Options
Upper Coilover Mount:Formed tabs weld to the outer tube and connect the bar to the rear crossmember using your 5/8" coil-over bolts (not included). Requires 1-3/8" dia outer tube.
Lower Axle Bracket Mount:A 10 ga formed bracket bolts to the lower coil over holes in the four link axle bracket and mounts the tube tucked nicely under the axle bracket. Holes are 5/8" dia on 1" centers. Requires 1-3/8" dia outer tube. With this option, the arms would attach to the bottom of your frame rail ahead of or behind the axle.
Under Frame Mount:These plates have two 3/8" mounting holes, with the opposite end designed to weld to the outer tube. With this option, the sway bar can be mounted underneath the frame rails ahead of or behind the axle. We have weld-in threaded bungs and hardware available to fasten the plate, if required. 1" from the top of the outer tube to the mounting hole centerline. Requires 1-3/8" or 1-5/8" dia outer tube.
Heavy Tube Crossmember:Available 43" long for the 45" sway bar, this 1-5/8" x .188" wall tube can be used as a rear frame crossmember to mount your coilovers. It is designed to go through the frame rails, with the sway bar arms outside the rails. No frame mounting tabs are included. The hardware package is the same as our standard trim to fit kits, except it substitutes the larger #1205 bushings. Our #18600 is a good option for the coilover mounts - check it out in the related parts. If you order the 36" kit and select the option for the heavy tube crossmember, you will receive a 36" long sway bar with a 43" long outer tube that you can trim to fit.
Three pairs of 3/16" thick tabs connect the sway bar outer tube to your 1-1/2" OD frame crossmember tube. Two pairs are mounted on the front of the tube and one pair is mounted on the rear in order to prevent the sway bar tube from rotating on the mounting bolt centerline if all three pairs were mounted in a row. Includes all necessary grade 5 zinc plated hardware. Requires 1-3/8" dia outer tube.
Pillow Block Bearing Mount
If you want to mount your sway bar underneath the frame using pillow blocks, here is the option for you. Select "no outer tube" and "no outer tube mounts". These bearing mounts have set screws at 12:00 and 3:00 to keep the bar from moving side to side. Just use a drill bit to create a small divot for a more secure connection. They will accept some misalignment as the bearing is mounted in a rounded cage and will pivot.If your unboxed frame is already painted and you want a bolt-on kit, please see the related parts below for a bolt-on pillow block bracket.
Two pillow block bearings are supplied. For mounting hardware options, see below.
Pillow Block Mounting Hardware
Option A: 3/8-16 nylok nuts for mounting to an unboxed frame rail where you have access to the nuts. Includes two pillow block bearings.
Option B: 3/8-16 threaded bungs to weld into a boxed frame rail. Includes two pillow block bearings and lock washers.
Option C: 3/8-16 tab weld nuts to weld inside the frame rail before boxing. Includes two pillow block bearings and lock washers.
Arm Mounting Options:
Axle Bracket TabsDesigned to mount the heim joints to 3" axle tubes. 10 ga. 3/8" hole.
Frame Mounting Tabs, 11/16"These 3/16" thick tabs will mount the heim joints nice and close to your frame rail. 3/8" hole.
Long Frame Mount TabsIf you need some more distance between the arm and the frame rail, these 3/16" tabs tabs might be the solution. 4" from the frame edge to the 3/8" hole center.
Control Arm TabsTypically used to mount the heim joints to a 1" dia tubular lower control arm. 3/16" thick, 3/8" hole. Also available for 1-1/4" and 1-5/8" tubing.
Quick release pins are also available so you can disconnect the sway bar arms easily. We suggest using them on the axle end because the heim joint is captured between the two axle tabs, and it can't slide along the pin.

Every customer is different. You’re different from the next customer. That’s why they’re called 'custom'ers. There is no formula, no equation that will work with all of you. It takes a different approach to everyone to determine how best to serve anyone. Some people need videos, some people need descriptions. Some people need us to weld it together. Our approach has been, and will always be, to serve each of you where you are and to treat you the same way we would like to be treated. We officially opened the doors to Welder Series in 2005. That doesn’t sound like very long, because the product line has been percolating for over 40. Paul Horton began developing and building many of the parts we still manufacture when I wasn’t yet a twinkle in Dorothy’s eye. Thanks very much for your business and support over the years.
-Paul, Dorothy, and DW (me) Horton
Note DW and Paul Horton at Welder Series absolutely rock and were quick, prompt, by far the best communication I’ve had with an online vendor in a LONG LONG TIME… (Sorry but their response time was bar none awesome). Very rarely do you find the level of dedication to a customer, communication, and a rewarding experience for both the buyer and supplier. I bought a pedal assembly a bit ago, and that experience automatically ensured that I will source Welder Series before I search for another vendor. Paul and DW have it together and will make a solution to your problem… and probably at the best price around to boot.
I have purchased a few of the products that Welder Series offers and been pleased each time. The products are as advertised and they ship in a timely manner.
I am also impressed with their customer service. I asked them if they had a brake pedal kit (mount, pivot, pedal, bushings, etc) for a right hand drive application. They did not have a kit per se but were able to put together pieces from their catalog to make one I could modify the Master Cylinder mount to make it face the other way (I had to cut the top off and weld it back on facing the other way, cheaper than ordering a one off part, and I don’t have a way to bend metal that thick, everything else fit up as intended). It worked as they described.
I just finished installing a Welder Series rear sway bar kit over the weekend. My all-steel ’35 sedan handled in the traditional “scrape off the running boards” way… even with a front sway bar. The kit went together nicely, everything fit perfectly and now the car goes around a corner 100% better… no more extreme lean. DW was a huge help in putting together a little bit different kit for me since I am using a tubular rear crossmember and also made some suggestions that really helped in the fabrication. You can depend on these guys… they are “for real” hot rod guys that offer really cool products. I’ll post a picture or two when I get the chance to put the car on a hoist for a better photo op. Thanks DW & crew.
