SPC Performance Jeep JK Cams

1993–1998 Jeep Grand Cherokee 5.2L V8 / 4.0L I6, 2007–2018 Jeep Wrangler 3.8L V6 / 3.6L V6 / 2.0L Turbo

Part #: 82390

Overview

The SPC Performance Jeep JK Cams are precision-engineered components designed to enhance the front axle alignment of select Jeep Grand Cherokee and Wrangler models. These cams replace the factory front axle bolts, allowing for adjustment of caster and pinion angles by up to 3 degrees total. This adjustment capability improves handling, driveline angles, and overall vehicle stability, especially after suspension lifts or modifications.

Ideal for Jeep enthusiasts and off-roaders seeking improved front-end geometry, these cams provide a reliable solution to correct pinion angle and caster changes that occur with suspension upgrades. By optimizing these angles, the SPC cams help reduce driveline vibrations and enhance tire wear characteristics.

Key Features

Designed for precise front axle alignment adjustments, the SPC Performance Jeep JK Cams offer the following benefits:

• Replaces OEM front axle bolts to enable caster and pinion angle adjustments up to 3 degrees total
• Compatible with multiple Jeep models including 1993–1998 Grand Cherokee 5.2L V8 and 4.0L I6, and 2007–2018 Wrangler 3.8L V6, 3.6L V6, and 2.0L Turbo engines
• Allows correction of driveline angles to reduce vibrations and improve drivetrain longevity
• Works in conjunction with SPC’s offset pin joints (part numbers 23510–23540) for additional caster and camber adjustments
• Enables elongation of OEM bolt holes using SPC’s knock out punch tool (#74910) for easier installation and adjustment
• Durable construction designed to withstand off-road conditions and heavy-duty use
• Improves front suspension geometry for enhanced on- and off-road handling

Construction & Design

SPC Performance manufactures these cams with high-strength materials engineered to endure the rigors of off-road driving and suspension modifications. The design focuses on durability and precision, ensuring that adjustments to caster and pinion angles remain stable under demanding conditions. The cams are engineered to fit directly in place of the factory front axle bolts, maintaining OEM mounting points while providing enhanced adjustability.

The ability to elongate the OEM bolt holes using SPC’s knock out punch tool (#74910) allows for fine-tuning alignment without compromising structural integrity. This thoughtful design ensures that the cams integrate seamlessly with existing suspension components and hardware.

Installation & Fitment

Installation involves replacing the factory front axle bolts with the SPC cams, which then allow for adjustment of caster and pinion angles. To achieve the full range of adjustment, elongation of the OEM bolt holes may be necessary using SPC’s knock out punch tool (#74910). Front caster angle will vary as pinion angle is adjusted, so it is recommended to use SPC’s offset pin joints (part numbers 23510–23540) to further refine caster and camber settings.

This product fits the following vehicles:

• 1993–1998 Jeep Grand Cherokee 5.2L V8
• 1993–1998 Jeep Grand Cherokee 4.0L I6
• 2007–2011 Jeep Wrangler 3.8L V6
• 2012–2018 Jeep Wrangler 3.6L V6
• 2018 Jeep Wrangler JK 3.6L V6
• 2018 Jeep Wrangler 2.0L Turbo

Professional installation is recommended to ensure proper alignment and torque specifications are met.
