Product Description

The SPC 35475 Adjustable Front Upper Control Arms address the alignment correction challenge that arises when lift kits push camber and caster beyond the factory adjustment range on the 2024-2026 Toyota Tacoma, 2025-2026 Toyota 4Runner, 2024-2026 Toyota Land Cruiser (250 Series), and 2024-2026 Lexus GX550. Built from lightweight forged aluminum - a notable upgrade over steel-construction SPC arms - these direct remove-and-replace arms deliver ±2.0° of camber and 0° to +4.0° of caster adjustment when used in combination with the OE lower control arm adjusters. The maintenance-free sealed ball joint features a 25% larger stud cross section than OE, E-Nickel corrosion protection, and 80° of articulation for maximum droop travel.

The xAxis™ sealed flex joints in bonded rubber bushings preserve factory-level NVH while allowing maximum suspension travel for both street and off-road demands. Arm adjustability combined with the OE lower cam adjusters also allows oversized tire positioning in the wheel well to be optimized without frame or fender modification. No cutting or drilling is required. A professional wheel alignment is required after fitting. Designed, engineered, tested, and assembled in Longmont, Colorado by SPC. Replacement ball joints are available separately under SPC part number 35102. Sold as a pair covering both driver and passenger sides.
