Thought i'd share with my impressions of the truck with the addition of the skyjacker control arms. I installed both the dul25 and dll23 arms (upper and lower arms). Truck is at stock height in the rear and leveled in front with the d25 skyjacker springs.
First the gripes. The lower arm is a bit longer than the stock arm. The upper arm is a bit shorter though which doesn't make much sense to me. What's happened is caster can't be gotten down to the optimal 3.2 or round about posative degrees. With the eccentrics maxed out caster is a posative 4.5 which is still within the spec I believe but a bit too posative. Also, it looks to me like a 35" tire will be very close when turning to hitting the fender. Currently only have the 31.6" toyo HTs on so can't say for certain how that will change or not. Perhaps because these arms are designed for between 3" to 5" lift they operate in this manner but pulling the axle back with higher lift would become an issue I think in regards to tire clearence with the rear fender.
Now, the good. The truck handles better at 4" higher than it was (from stock coils with one coil cut to skyjacker d25s about 4" taller) then it ever did at the lower height. My stock arms had the bushings in horrible shape and two of them were bent so i'd imagine some of this is due to that. I can take corners I couldn't dream of before. Actually on the way home tonight I came around the long sweeping turn so fast I uncovered the pickup of the air dog 150 and nearly stalled the truck out with 1/4 tank of fuel. Never had that happen before. I know the point of these trucks is not hair pin turns but the increase in handling is certainly nice!
For around $140 per pair i'm happy with the purchase. I also have a DSS and 3rd gen adjustable solid steel track arm with conversion so take that into consideration.
Just figured i'd put up a thread given when searching for threads discussing both arms used together I couldn't find any.
