Driveshaft Shop 850HP Intermediate Bar for 02-06 DC5 RSX Type S

Driveshaft Shop 850HP Intermediate Bar (KA2727) - K-Series

The intermediate bar is the part between your transmission and your passenger side axle, and on a high power K-series it's a link in the chain that gets overlooked. People upgrade axles, keep the factory intermediate shaft, and find the weak point simply moved. This is Driveshaft Shop's answer: aircraft quality material, rated to 850 horsepower, and a direct replacement that needs no modification.

Same 27-Spline As Factory

This is what makes it straightforward, and it's worth stating plainly.

The bar is made in the same 27-spline size as the factory intermediate shaft, which means it fits your stock differential or a spool without any changes. No adapters, no different differential, no machining.

It's a direct replacement in the truest sense. Pull the old one, put this in, done.

You'll Reuse Your Hanger Bearing And Bracket

Important before you order, because these aren't included.

Your factory hanger bearing and bracket carry over. They're what supports the intermediate shaft at its outboard end, and Driveshaft Shop designed this around the factory pieces rather than replacing them.

So take a look at yours before the job. If the bearing has real miles on it or feels rough, that's worth addressing while everything is apart rather than putting a new bar into a tired support. Coming back for a hanger bearing later means undoing work you just did.

Why The Intermediate Bar Matters

Worth understanding if you're wondering whether this is necessary.

On a transverse front-drive layout, the passenger side axle is too far from the transmission to run directly. The intermediate shaft bridges that gap, which means every bit of torque headed to that wheel passes through it.

At stock power the factory piece is fine. Add real power, sticky tires, and hard launches, and it becomes a component seeing loads it was never designed around. Upgrading axles while leaving the intermediate shaft alone just relocates the failure rather than preventing it.

An 850 horsepower rating puts this well clear of what most K-series builds will ever ask of it.

Pairs With Performance Axles

This is designed to work alongside Driveshaft Shop's performance axle lines, and running them together is how you get a complete drivetrain rather than a partial upgrade.

If you're already replacing axles on a high power build, adding the intermediate bar in the same order makes sense. Same job, same access, and it means the whole path from transmission to wheel is rated for what you're making.

Who Should Run This

This is for the K-series builder who's upgrading the drivetrain properly rather than one piece at a time, and for anyone who's found the factory intermediate shaft has become the limitation. It bolts in with no modification, it uses your existing hanger bearing, and it takes the intermediate shaft off your list of things to worry about. Check your hanger bearing condition while you're in there, and get the whole path sorted at once.
