early vs late idler arms?

Matt16 · 12-26-2008, 02:03 PM

I know the later model idler arm (post '92) is a little beefier than the early ('86-'92). I am ordering a Downey Idler arm gusset and there is a different gusset for each idler arm.

Are there any features which easily distinguish between idler arms? I do not know the year that my junk-yard idler arm came off of.

or, is it possible to upgrade a stock idler to the stronger style?
like me with my 90?

I don't think the later idler arm is really much stronger, maybe something like 5% stronger, I don't know, whereas the brace/gusset is maybe 100% stronger.

The diameter of the idler rod (haha...rod) is bigger then the 91 and prior units.

My downey idler arm brace was for a 1993 idler arm (I got the arm too) and it fit fine on my 91 arm..

There are two part number, on for each idler arm, which is confusing me.

No, don't think so, good guess though.

Steering idler arm gusset

Downey invented the Idler Arm Gusset; it is no more than another remedy for another problem. As we discover what can be bent or broken, we produce the bullet proofing. Most cases of bent idler arms are found on Toyota’s with 4 inch lift kits, but occasionally we find a bent Idler Arm on a Toyota less radically equipped, but more radically used off road. The idler Gusset is a simple bolt-on device, silver powder painted for lasting durability.
