Key Features
- 8 Polyurethane Bushings: 4 for upper control arms (2 per side) and 4 for lower control arms (2 per side), all in Prothane’s signature red finish.
- Enhanced Ride Quality: Reduces suspension slop and improves front-end feel, making your truck feel like new. Ideal for towing, hauling, or aggressive driving.
- Vibrant Red Finish: Not only functional but also visually striking, the red bushings add a bold, custom look to your suspension.
- Orientation: For lower control arm bushings, ensure the shoulder faces the front of the vehicle.
- Preparation: Burn out old rubber bushings from upper control arm sleeves (if reusing) and clean thoroughly. Lower control arm sleeves are included but may require deburring or slight machining for perfect bolt fitment.
- 4 Metal Sleeves for Lower Control Arms: Precision-machined sleeves for the lower control arm bushings, designed to accommodate factory bolts (5/8” diameter). Note: Upper control arm bushings require reusing factory sleeves or custom machining in some cases.
