SuperPro 1990 Lexus LS400 Base Front Upper Inner Control Arm Bushing Kit, manufacturer part number SPF1352K, is a new SuperPro bushing kits product selected by the verified year, make, and model records below. Confirm the mounting position, dimensions, bar diameter where applicable, included components, and every current manufacturer application note before ordering.
Key Features
- The SuperPro SPRSPF1352K replaces those tired rubber bushings with polyurethane at the front upper inner mounting location, locking in consistent geometry mile after mile.
- The SPRSPF1352K is a SuperPro polyurethane bushing kit that replaces the worn front upper inner control arm bushing on the 1990-1994 Lexus LS400.
- Common signs include vague or wandering steering, uneven front tire wear, and a clunking noise from the front suspension over bumps.
- Polyurethane is firmer than factory rubber, which slightly increases feedback through the chassis but delivers noticeably more precise and consistent handling.
- If the wander is caused by worn front upper control arm bushings, replacing them with this kit restores the correct geometry and typically resolves the issue.
- Yes, an alignment is recommended after any front suspension bushing replacement to ensure camber and caster are set correctly.

Frequently Asked Questions
How do I confirm SuperPro SPF1352K fits my vehicle?
Match the exact year, make, and model where listed, then verify the mounting position, component dimensions, suspension configuration, drivetrain, and every manufacturer qualifier.
Are similar SuperPro bushings interchangeable with SPF1352K?
No. Outside diameter, inside diameter, installed width, sleeve size, bracket geometry, bar diameter, and position can differ even when parts look alike.
What should be checked after installing SuperPro SPF1352K?
Confirm fastener torque, component seating, full suspension travel, steering and driveline clearance, and any required wheel alignment. Reinspect the installation after the initial settling period.
Installation
Follow the current SuperPro instructions and the vehicle service procedure for this exact part number. Support the vehicle safely, compare all supplied parts before disassembly, lubricate only the specified surfaces, torque hardware in the required suspension position, verify full travel and clearance, and complete any required alignment and post-installation inspection.

Compare a standard replacement with a manufacturer-supported performance or adjustable option for the actual pivot.A design that reduces unwanted deflection can sharpen the supported mounting pointβs response, but isolation and articulation also matter. Evaluate material, geometry and installation together rather than expecting every firmer bushing to deliver the same ride or service life.Steering, Sway-Bar and Drivetrain M...
