SPC Performance 23137 Cam/cas Slv Alignment Caster / Camber Bushing - 1-3/4 4x4

The SPC Performance 23137 Cam/Caster Alignment Sleeve provides precision adjustment of camber, caster, or both simultaneously on 4x4 vehicles. This 1-3/4" sleeve replaces the factory upper control arm sleeve to correct alignment issues caused by lifted suspensions, worn components, or modified ride height.

Key Features:

• Adjustable camber and caster correction for 4x4 applications
• 1-3/4" diameter sleeve design for upper control arm mounting
• Allows independent adjustment of camber and caster by rotating sleeve 45 degrees
• Works with SPC zero degree sleeve (23139) for baseline measurement
• Precision-machined construction for accurate alignment settings
• Installs with standard alignment tools and sleeve puller

Installation Overview:

Remove the tire and disconnect the upper ball joint by removing the cotter pin and stud nut. Break the taper between the stud and sleeve, then use a sleeve puller to remove the existing sleeve. Install a zero degree sleeve (SPC 23139, sold separately) to determine the alignment change needed, then install the correct angle sleeve. To split camber and caster adjustment independently, rotate the sleeve 45 degrees during installation.

This alignment sleeve is designed for professionals and experienced enthusiasts seeking precise suspension geometry correction on lifted or modified 4x4 trucks and SUVs.
