KSP Front Upper Control Arms for Toyota Tacoma 4Runner N180

In this review of the KSP Front Upper Control Arms, the bottom line is simple: these are a practical replacement for owners of lifted Toyota Tacomas, 4Runners and Prerunners who need stronger, adjustable upper arms that correct suspension geometry after a 2-4' lift. The reviewer found the tubular design, greaseable ball joint and powder coated finish to be the single biggest reasons to buy, since they address fitment after lift, contamination resistance and durability compared with typical stock arms.

Key Features

• Fitment: Designed to replace factory upper arms on specific 1995-2004 Tacoma, 4Runner and Prerunner models to restore proper suspension geometry after a 2-4' lift.
• Adjustability: The 2-4' adjustable tubular A-arm design allows alignment correction and ride-height compensation for lifted trucks.
• Durable construction: Thickened cold-drawn steel pipe and CNC machined components provide a bolder pipe diameter and improved strength over stock arms.
• Greaseable ball joint: A greaseable socket with a pre-installed dust boot lets fresh lubricant flush contaminants to extend service life.
• Corrosion protection: Powder coated surface reduces rust and corrosion for longer outdoor use and rough weather resistance.
• Serviceable design: Ball pin with hex hole and zerk fitting make installation and periodic maintenance straightforward when needed.

Who It's For

The arms are best for owners of 1996-2003 Toyota Tacoma 4x4, 1996-2004 Toyota Prerunner 4x2 and 1995-2002 Toyota 4Runner N180 who have lifted their vehicles 2-4' and need a stronger, adjustable upper control arm to correct alignment and chassis geometry. They suit DIY mechanics and professional installers who value greaseable joints, pre-installed dust boots and hardware that simplifies the swap.

These arms are not aimed at owners of unlisted years or models, or those who need custom fabrication beyond the advertised adjustability; if you require a different fit or wider aftermarket modifications, check compatibility carefully before purchase.

Pros & Cons

Pros

• Sturdy tubular and CNC machined construction improves durability and fit after a lift.
• Greaseable ball joint and dust boot protect components and allow maintenance when necessary.
• Powder coated finish resists rust and keeps the arms looking good over time.

Frequently Asked Questions

Will these fit my 1998 Tacoma with a 3' lift?
Yes, the arms are designed for 1996-2003 Tacoma 4x4 and to correct geometry for 2-4' lifts, but verify fit and plan for a post-install alignment.

Do the ball joints come pre-greased?
Yes, the new ball joints are pre-greased and do not require extra grease within the first year; use the zerk fitting thereafter and avoid over-tightening.

Is installation hardware included?
Customers report the arms come with required installation hardware, though professional installation is recommended for best alignment and safety.
