Truck: 2025 SuperCab 6.5' bed 4x4 (Street truck only, won't be towing)
I recently removed the blocks, installed the UMI drop shackles ( Link here ), Belltech Street Series 2WD shocks (Link here), Ford 2WD Bump Stops, and VAS traction bars (Link here). Overall, installation was pretty easy. Get the stock shackle up near the bed to remove the top bolt. NO CUTTING REQUIRED with UMI Shackles. After installation, I lowered the truck back to the ground and torqued down the shackles using the truck's weight.
Pinion: Measurements check out and NO Shims necessary! NO VIBRATION under any loads or speeds. (Don't ask me how, but they even claim shims aren't needed on their website, stoked this was the case as I bought 2.5º shims just in case)
VAS traction bars adjusted to Street setting (bump stop 1/4" away from leaf spring).
Installed for one week now, this combination feels and performs so nicely! The new shocks and traction bars paired together really put the power down and keep the rear end tighter (feels more like a nice sedan than a truck).
