FAQS on spindle source upper control arms

Q: What are the benefits of Spindle Source upper control arms?

A: Spindle Source upper control arms improve suspension geometry, enhance steering stability, and are designed for lifted trucks to reduce wear on joints and bushings.

Q: Are Spindle Source upper control arms compatible with a 3-inch lift?

A: Yes, Spindle Source offers upper control arms specifically engineered for 3-inch lifts, ensuring proper alignment and reduced strain on suspension components.

Q: Do I need upgraded upper control arms for a 6-inch lift?

A: Absolutely. Upper control arms for 6-inch lifts correct extreme angles, restore caster, and prevent premature wear caused by aggressive lift heights.

Q: How do Spindle Source upper control arms differ from stock arms?

A: They feature stronger materials, adjustable design for lifted setups, and reinforced joints to handle off-road stress better than factory arms.

Q: Can I install upper control arms myself?

A: While possible, professional installation is recommended to ensure precise alignment and torque specifications for optimal performance and safety.
