Sway Bar Kit, Trim To Fit, 1" Bar

Sway Bar Kit – Customizable and Built for Performance

This sway bar kit is available in 45″ or 49-1/2” lengths but can easily be cut to any size using a hacksaw to suit your application. The sway bar is made from 1″ diameter solid 4142 heat-treated, cold-finished steel, ensuring strength and durability. Both ends of the bar are smooth for easy assembly.

Key Features:

• Bar Construction: Solid steel bar with smooth ends that can be securely attached to couplers using heavy-duty 1/4″ coiled spring pins and/or welded (optional). The couplers get welded to the arms for a strong connection.
• Arm Options: Choose from 8″, 12″, or 17″ arms (laser-cut from 3/8″ thick steel). Arms have a ~7/8” offset. You can bend them to clear the front tires in a turn.
• Mounting: Optional Delrin bushings isolate the sway bar inside a 1-5/8" OD DOM outer tube for smooth performance, or use pillow block bearings to mount the bar directly below your frame. Adjustable rod ends connect the arms to the tabs welded to the frame or rear end.
• Customizable Fit: The sway bar's overall length is ¾” longer than the bar itself, accounting for the 3/8″ thick arms mounted on the ends. The arms can be bent to clear coil-overs (rear sway bar) or tires (front sway bar) for added flexibility.

About the Coiled Spring Pins:

• These spiral pins stay flexible after installation, absorbing shock and vibration better than standard slotted pins.
• Tension fit: They hold tight against the hole wall.
• Chamfered ends: Make installation easy.
• Breaking strength: Rated at 5,500 lbs in double shear, providing exceptional durability under stress.

Hardware Package

This is the basic hardware package that comes with every kit. Heim joints are Teflon lined and made in the USA. They now come in a yellow zinc plating. Both couplers are supplied with 1" smooth ID couplers.

Arm Mounting Options:

Axle Bracket Tabs

Designed 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 Tabs

If 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 Tabs

Typically used to mount the heim joints to a 1" dia tubular lower control arm. 3/16" thick, 3/8" hole.

Sway Bar Mounting Options

Pillow Block Bearing Mount

If you want to mount your sway bar underneath the frame using pillow block bearings, 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.

Note: bars will not be supplied splined.

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.

Tube Mount
Like our 3/4" sway bar kit, this kit is also available with a 1-5/8" OD x .188" heavy wall outer tube mount. The 1" bar is isolated with CNC machined Delrin bushings. This outer tube can be installed through the frame rails to mount the arms outside the rails. It is strong enough to be used as a crossmember to mount coilovers or Shockwaves to.

Under Frame Mount:

These plates have two 3/8" mounting holes, with the opposite end designed to weld to the 1-5/8" outer tube. With this option, the sway bar can be mounted underneath the frame rails. We have weld-in threaded bungs and hardware available to fasten the plate, if required. 1" from the top of the 1-5/8" tube to the mounting hole centerline.
