The Speedway Engineering 607 series sway bars are our lightest bars that aren't turned. The 607 series is a perfect solution for those wanting more grip in the rear but still want the stability of the sway bar. These bars are most common in Drifting, Off Road, Circle Track Racing, various types of road racing and Hot Rods.

We offer them in a 5/8-36 spline, 3/4-48 spline and a 7/8-48 spline and we stock a full range of arm and mounting options for each diameter. Stocking lengths are 32, 33, 34, 35, 36, 36.5, 37.5, 38.5, 39, 40, 41 and 42". Custom lengths are 3 to 5 days away.

The Speedway Engineering 604B Series Billet Pillow Blocks are designed to provide a more rigid, serviceable, and adjustable solution. When a mounting tube doesn't fit your application, this is the ideal way to mount a sway bar. All of the dimensions match our 605B series pillow block for a simple direct replacement.

Eliminate Bind

The 604 Series uses a sealed spherical bearing that allows the joint to articulate as the suspension moves. This helps eliminate unwanted bind and allows smoother suspension movement.

Rigid Billet Construction

The 604 Series provides a rigid mounting point with reduced deflection compared to traditional stamped steel designs. This helps maintain more consistent suspension geometry under load.

Built to Be Serviced

In most applications, the sway bar is mounted in a very dirty environment. The 604 Series is designed with a serviceable sealed spherical bearing, making it an easy to disassemble and clean regularly.

Size Range

Stocking diameters are 3/4", 1" and 1-1/4". Other options are available by special order.

Billet Collar Clamps

Our Billet Collar Clamps (605C Series) are made from aircraft grade 2024 aluminum which is significantly stronger than standard 6061 collar clamps. Our precision machined inside diameter provides concentric, full surface contact with the shaft, resulting in a uniform clamping interface.

A fresh batch of our GM Midsize hubs! When strength and stopping power matters, theses hubs are a great way to avoid cast hubs when you have to use stock style spindles.

These hubs will fit on any spindle that uses bearing set #6 (outer) and set #3 (inner) which is found on the GM #2, Metric Three Piece and more.

Hub offsets are specifically designed for you to use existing brake calipers and mounting positions. Many rotor adaptor options are available to give you the braking power and longevity you need.

Another custom kit out the door! We helped our customer pick out a 1" solid sway bar for their application. This one went with a mounting tube rather than pillow blocks to add some rigidity to the front of their chassis.
