Question about control arms

[makoshark]

I am looking to purchase a new set of control arms. I have Ridetech suspension and am leaning towards their control arms. However, I am curious why they used poly bushings instead of del-rin as the rest do? Is there any long-term effects that can create any adversities by using poly bushings?

As you can see we will soon be offering Delrin bushings in select control arms (we need to start with the popular, and most track driven, applications).

Opposed to most manufactures who machine their bushings from a solid rod we chose to injection mold our Delrin bushings, and here's why:
-we use Delrin with 13% PTFE (Teflon)
-regular Delrin rod is relatively inexpensive while Delrin with PTFE rod is quite expensive
-Delrin with PTFE in pellet form (so you can injection mold it) is much better price wise, but you have to order a metric crap ton, so you have to make a lot of parts to justify the tooling and material price
-our feeling was if you go to Delrin you might as well use a self-lubricating material so you don't need grease zerks and maintenance

So in the end we paid the tooling, bought a bunch of material, and designed a Delrin bushing that is a direct replacement for the Poly bushings we've used for so long.

The lower control arms are not really an issue as almost all of them use a Poly part. . .so we just drop in a Delrin part and we're done.
The upper arm, however, typically used an OE style rubber bushing, so we had to re-design the control arms.
This required a new control arm shaft for some applications so we took the opportunity to create a completely new cross shaft for the A/F (first gen)/X and G Body vehicles. This shaft has a lot of cool features including:
-self lubricating Delrin bushings
-offset shaft (for better Camber settings)
-caster slugs (for easier caster settings)
-one side of the shaft is "locked" in place so the arm cannot flex under braking

As I stated, we have to do the most popular, or most tracked, applications first. This means GM A/F/X and G Bodies come first. The rest will be done as quickly as possible after that.

These new parts will be available early in the New Year, so keep an eye on the website and we'll post up info as soon as we have parts in stock.
