Default Aftermarket rear sway bar question.

I have a rear sway bar from TMS , I'm finally about to install it. Do I need aftermarket adjustable end links? Everyone I talked to including turner said I can use oem end links. BUT the bolts looks like it's not going to fit into the end links bushings. I searched and old topics are 50/50 on the subject.

That's the bolt that goes through the sway bar itself?

I was always under the impression that the rear TMS bar required their adjustable links. At this point I forget why I thought that.

Yeah I'm probably going to go with the adjustable. People said the stocks will work but I doubt it. Plus I'm on coils and lower which apparently is a issue because the sway bar either hits the lower control arms or is just loaded with tension at all times. At least that's what old forums from 2009-13 say.

Where did that bolt come from? You could get a smaller one. My thinking is that the front links both have ball joints and can angle the way they need to for an aftermarket bar that might differ from OE, but the rear is fixed at both ends. I suppose you'd always want adjustable for an aftermarket bar, but fronts can get away with stock links?

In fact, maybe Turner's answer was about fronts, really, not rear.

The bolt was provided by Turner when I ordered it.

I used the OE end links with my H&R sway bars in the past, Turner is the same thing just painted blue.

However H&R includes a different bolt that fits through.

Try to use a SS Bolt with the same thread diameter but without the enlarged diameter at the end.

Default Re: Aftermarket rear sway bar question.

But since I'm lowered wouldn't the oem end links cause the sway bar to hit the rear camber arms? That's what I keep reading. Everything I keep reading is years old though.

How much are you lowered from original height?

When I was just 15mm lower it worked fine with OEM.

I have since moved on to aftermarket, because I do not like rubber in my suspension.
