Synergy Manufacturing Super Duty Caster Sleeves - F-250/F-350

The Synergy Ford Super Duty F-250 / F-350 caster sleeves are highly recommended when lifting or leveling your truck 2.5in. This ball joint Dana 60 sleeve shim provides 2.4 degrees of caster and -1 to +.4 degrees of camber. When leveling your Super Duty, the suspension geometry changes causing the factory spec caster to decrease. By installing these caster shims, the factory caster is restored to stock specifications. This helps maintain your steering return to center and overall factory steering feel.
