Type E EZ-IRS, Bolt-In IRS kit, 1955-1967 bus rear suspension. NO CORES NEEDED!!

$1,550.00

This kit was designed to overcome most all of the issues when trying to adapt a modern independent rear suspension into an early split bus. It was also designed to offer quite a few different mounting and width options with ZERO cutting or welding, AND NO need to send in original core parts to be cut down or modified.

The new-manufactured arms are built with a jog to clear the stock bus cross member even when being lowered. By providing the drop at the hub rather than at the splines, the rear camber is eliminated, and the stock payload and ride quality are retained.

Because the hub is separate from the arm, the overall track width is somewhat adjustable by using different mounting positions. There are also easy adjustments for camber, toe, and ride height.

The simple bolt-on torsion housing mounts are built to clear the heater tubes and frame horns with no cutting. They can also be easily adjusted to dial-in camber. Adjustable spring plates also dial-in ride height with one bolt adjustment.

The offset of the hub allows for a stock replacement Type 1 Bug CV assembly to fit without narrowing the torsion housing.

The rear hub accepts standard type 1 bug IRS stub axles, bearings, seals, and clips for easy replacement. Most standard T1 Bug rear brake systems should also fit.

This kit is now sold with 100% new spring plates. NO cores will need to be sent in.

Because of the huge number of options, brakes are not included in this kit.

The hubs comes with a caliper bracket welded to the hub. This bracket works with the CB and the newer style Empi T1 rear park brake calipers. You can order the calipers and rotors separate from CB/Empi, without needing to order an entire T1 kit. All you need is the IRS rotors, and R/L calipers.

This kit will be offered with or without all of the small hub parts. If you have a 1969-on Type 1 parts car, you can use those parts. If you do not have the hub parts, there is an option to purchase all of the bearings, seals, clips, stub axles, and CV assemblies.

This IRS kit is designed to work with 69-on T1 bug, or T3 squareback IRS transaxles.

Adding the hub parts option adds $485 to the kit, but it will provide you with all of the small parts, and no parts-car scrounging. This small parts kit does not include brake rotors or calipers, just the small parts inside the hubs, and the drive axle parts.

Some assembly required. You will need to be able to correctly pack the wheel bearings and assemble the hub and correctly torque the axle nut per factory settings.

These kits come raw welded steel.

Absolute top notch!!

There is no choice, this is the kit to invest in. It is absolutely top notch. I bought the small parts kit as well, EVERYTHING you need to get the job done, minus the calipers, rotors and gear box. Super happy I went this route.

Best IRS kit you could ever buy

This IRS kit is the best engineered piece I have ever seen, finally someone understands camber and caster when buses are lowered, perfect fit, no cutting, no welding, a true bolt on kit, and the wheels fit perfect in the wheel arch, the kit comes with everything you need and at most would take a day to fit. Brian has raised the bar on IRS kits and you would not find a better kit. Ian from Australia

So Grateful for Brian and this IRS kit

For those of us without a ton of fabrication experience, space, or time, having an affordable bolt-on kit available to easily convert our buses to IRS is a godsend. Brian created a kit that allows for that necessary drop, doesn’t require cutting, and has heaps of adjustability. His kit was installed without a hitch, he makes it idiot proof and provides all the necessary parts in a nice complete package. Empi Deluxe rear disc kit bolted up perfectly. The ride is incredible, the build quality is impeccable, and I couldn’t scream loud enough how much I endorse Brian and his products. He continues to be an easily accessible resource many months after my original purchase and flexes his ingenuity, insights, and support into how we can potentially introduce air ride components :). Happy to chat in-person or provide any photos of the kit installed or mid-assembly.
