Trail Forged HD front axle bushing upgrade kit.
Front upper control arm bushings (axle side) for most Jeep models (XJ, MJ, YJ, ZJ, TJ, LJ, WJ, JK) with factory Dana 30 or 44 axles. These are a precision made, top quality factory style rubber bushing with some major upgrades:
- 1/2″ bolt hole is the largest size of any factory style rubber bushing ¹
- Premium quality elastomer for superior durability and ride comfort
- Included 1/2″ NF Grade 8 mounting hardware for a serious upgrade in strength
- Requires drilling out upper control arms to 1/2″ on all Jeep models except some JK’s (JK uses a 12mm bolt factory, which is about 0.027″ smaller than 1/2″)
