KSP 2-4in Upper Control Arms for 2004-2020 F150 - 2 to 4 Lift

In this review of the KSP 2-4in Upper Control Arms, the bottom line is simple: these tubular replacement arms are for F-150 owners who want a durable, OEM-style upgrade that will lift the truck 2 to 4 in and improve off-road geometry. The reviewer found the arms noticeably sturdier than factory pieces, with MIG welded construction and larger tubing that give a clear safety and build-quality advantage. Installation is straightforward for someone comfortable with suspension work, though an alignment is required after fitting.

Key Features

• Fitment: Designed specifically for 2004-2020 F150 models, ensuring the mounting points match stock locations for a direct replacement.
• Lift range: Provides a conservative 2 to 4 in lift without requiring shock replacement in many setups, keeping costs down for modest lifts.
• Construction: MIG welding and larger tubular arms deliver improved strength and perceived long-term durability compared with stock control arms.
• Bushing and ball joint design: PU bushings and supplied ball joints are intended for low-temperature resilience and reduced deflection under load.
• Serviceability: Dust caps and greaseable zerks are included to extend service life, with a note to avoid over-tightening the copper zerks.
• Support: KSP offers a 30-day refund policy and 12-month free ball joint replacement for added buyer confidence.

Who It's For

This product is best for F-150 owners who want a stronger replacement for factory upper control arms and plan a modest lift of 2 to 4 in while retaining stock shocks. It appeals to DIY installers and professional shops who need welded tubular arms with grease fittings and PU bushings for improved handling and off-road use.

Drivers who run conservative stock wheels with ET44 should note potential clearance issues; they may need at least a 1.5 in wheel spacer or zero-offset aftermarket wheels. If you run large aftermarket rims or uncommon offsets, check fitment with the seller before buying.
