Billet Rear Subframe Bushing Lockout Inserts (Pair) - WK2 Grand Cherokee & Durango (Trackhawk, SRT, Hellcat)
Billet 6061 lockout inserts for the WK2-platform rear subframe bushings, sold as a pair (one per side). Fits every WK2 Jeep Grand Cherokee and WK2-platform Dodge Durango, from the base V6 up to the Trackhawk and Durango Hellcat. 100% designed and machined in-house in Texas.
The factory rear subframe bushings are heavily voided to isolate the cabin. On a high-power build that void space lets the subframe shift under launch, which costs traction, upsets alignment and adds to wheel hop. These inserts fill that space and lock the subframe in place.
Features
- CNC-machined from 6061 billet aluminum
- Two-piece design that wraps the full length of the bushing, not just the top
- Installs into the factory bushings, no pressing out bushings
- Bolt-in, uses factory hardware
- Tighter, more consistent launches with less subframe movement
What's included
- 2x two-piece lockout insert assemblies (left and right)
