Here's the deal. Got a little side project here and these arms just got upgraded with Synergy's new bushing. So thought we'd give it a shot.
Picked them up for 10% off at the independance day sale at Poly. Couple hundo delivered. Good deal. Link here...
Anyway, the goal here is the goal of better than 90% of Jeepers who lift their rig. Make it bomber, make it easy, make it durable and make it work.
Since this is JK tech, this product may be too basic for many of you, but for the vast majority of Jeepers, these arms just make sense.
So I ripped them out of the box and noticed that they are light. Damn light. Like half the weight of the RK arms we installed on a different rig earlier. So out comes to engineering book. Let's see here... 23" tube, 1.75" diameter, .188 wall thickness, DOM 1026, carry the 3.... Presto! Yield of about 6,000 lbs.. Impressive. And more than sufficient for dragging over rocks.
Why fixed length? There are tons of nice adjustable length LCAs. Many available for the same price as the fixed Synergys. So why? Simple. No set.up. No worries about jam nuts loosening. No crowfoot wrenches under the Jeep at weird angles.
The new dual durometer bushings are also cool. Strictly guessing, they don't seem to offer as much misalignment as a mechanical joint. But there are two, so it evens out. In any event, they don't limit the 11" of travel we needed to cover.
That's it. No muss. No fuss. On in half hour and never have to dick with them again. Bam!
The Jeep in question went with 2.5" RK coils. Proven performers. Smooth ride. Honest ride height. Caster should be pretty much factory. Thing drives great. High speed hits could not provoke any wobble or nastiness.
All in all an easy install for a set it and forget it kind of Jeep.
My prediction is that others will join Tera and some other players in offering fixed length lift corrected arms. It just makes too much sense for the vast majority of real world Jeeping.
