Default Unknown ALK

So I have a pair of ALK bushings that my friend said were group-n, but he said he's not sure. I needed to install them to get my car running after an accident, so I didn't have the chance to take any pics. They look identical to the wrx ones except they have 4 slots on the rubber material (arranged to make a square) that surrounds the inner metal circle. The bushing seems a little stiffer than the wrx ones, but not by much. Anyone have an idea?

The only GroupN one I know of is GTSpec, and they're solid rubber as well as having GTSpec engraved on the side.

Tough to say. I've never looked at mine. Do you mean just a "graphic" in the shape of a square or like holes through the bushing? By graphic I mean raised rubber to form a picture of sorts.

gtspec is NOT group n

the ONLY group n bushing will be made by subaru as a group n part

if the bushing is just that and is not in a mounting housing then it is not an 'alk'

if the bushing was urethane then it was aftermarket

Do these fit in the stock housing or do they have their own anodized aluminum pieces.? The Gt-Specs are anodized blue, Whitelines are gold, and the Perrin PSRS are red IIRC.

Ok, Group N level firmness but not "Group N" branded...if this is actually a brand name. How about that? Acceptable?

Like I said... they seem identical to my wrx ones, except for the hardness of the rubber and the slits that cut through the entire bushing. They have their own anodized aluminum pieces, just like stock. It's as if someone took a kinfe and stabbed the bushing all the way through. I'm thinking it might just be stock on another subaru, but I just wanna know for sure.

Btw, is the bushing even removable on the stocker? I was always under the impression that it wasn't...

Well, an ALK won't be the same as the stock piece anyways. The metal bracket is thickened (copied off the Forester design), to lower the back end of the control arm, promoting more dive, less binding when loaded, and more kick-up on the front which improves off road behavior.

It may be an oem piece. A Group N or equivalent one should be a rather noticeable change in handling precision. Along with upgraded steering rack bushings from Whiteline, the front end and steering gets very precise and direct.

'group n' is a rally competition class and ruleset that rally cars must ahdere to to compete in group n rallys

'group n' parts meet the regs required for 'group n' competition

subaru 'group n' parts are subaru factory performance parts produced for subaru 'group n' rally cars

group n parts have not been, and are not available on cars from the factory
they are ordered and installed aftermarket style


there is no subaru alk nor group n alk

alk is a Whiteline brand name for their rear transverse link bushing and its housing assembly and associated hardware

It's sort of similar but also completely different. The forester bushing just compensates for the spaced down subframes and added ride height. The [Whiteline] ALK does some other stuff.
