SuperPro SPF1922K Rear Upper Control Arm Inner Bushings for Toyota Supra/Soarer

Vehicle Fitment

• 1993-2002 Toyota Supra (JZA80, 2JZ-GE, 2JZ-GTE)
• 1990-2000 Toyota Soarer (Z30/Z32, UZZ30/JZZ31)
• 1993-1996 Toyota Aristo (JZS147)
• 1993-1997 Lexus GS300 (JZS147)
• 1992-2000 Lexus SC300 (JZZ31)
• 1991-2000 Lexus SC400 (UZZ30)

Fitment Notes

• Fits the rear upper control arm inner (chassis-side) bushing position only. Does not replace the outer or knuckle-side bushing.
• OEM outer bushing shells must be removed during installation; the SuperPro bushings replace the rubber insert within the existing shell housing.
• Wheel alignment is required after installation due to changes in rear suspension geometry.
• Fits both Turbo (2JZ-GTE) and Non-Turbo (2JZ-GE) variants of the JZA80 Supra.
• Compatible with both RHD and LHD variants across all listed platforms.

Features

• Replaces the OEM rubber rear upper control arm inner bushings with SuperPro's proprietary engineering-grade polyurethane, eliminating the deflection and compliance that degrades rear wheel alignment consistency over time.
• Knurled bushing surface design actively retains lubrication, preventing squeak and eliminating the need for periodic re-greasing during normal use.
• Reduces rear camber and toe variation under load, cornering, and braking - improving steering feel, rear stability, and overall chassis response.
• SuperPro's proprietary polyurethane formulation delivers the dimensional precision of a performance bushing without the NVH penalty associated with standard polyurethane products.
• Fully resistant to extreme temperatures, oils, water, and coolant - maintaining consistent performance over the full lifespan of the bushing.
• Engineered, designed, and manufactured in Australia using SuperPro's fully in-house process for consistent material quality and dimensional accuracy.
• Backed by SuperPro's lifetime warranty covering failure and defect, with no exclusions for track, competition, or motorsport use.
• Direct OEM-dimension replacement - no modification to the control arm or chassis required beyond standard bushing removal and pressing.

Product Description

The SuperPro SPF1922K is a rear upper control arm inner bushing kit engineered for the Toyota Supra JZA80 and its Z30/Z32 platform siblings - the Toyota Soarer, Toyota Aristo, Lexus GS300, Lexus SC300, and Lexus SC400. These vehicles share a sophisticated multi-link rear suspension geometry that depends heavily on bushing integrity to maintain consistent rear camber and toe settings under load. As the OEM rubber bushings age, they soften, crack, and deflect - allowing the rear upper control arm to shift dynamically under cornering, braking, and acceleration forces. The result is inconsistent rear alignment, imprecise steering response, and accelerated rear tire wear. The SPF1922K directly replaces the rubber bushing inserts in the rear upper control arm inner (chassis-side) mount with SuperPro's proprietary polyurethane, restoring dimensional rigidity and eliminating the compliance-induced geometry variation that degrades handling over time.

SuperPro's polyurethane formulation is specifically engineered to avoid the NVH compromise that makes conventional polyurethane bushings undesirable on street-driven cars. By carefully controlling the durometer and internal geometry of the bushing - including knurling that actively retains lubricant - SuperPro has produced a material that reduces deflection and extends service life without transmitting road noise or harshness into the cabin. The knurled surface eliminates squeak permanently without any maintenance requirement, as long as installation grease is applied at fitment. A lifetime warranty covers the bushings against any failure or defect, including in competition and track use - making this equally suitable for a daily-driven Supra or a dedicated drift and time attack build.

Installation requires removal of the OEM outer bushing shells before the SuperPro inserts can be pressed in, and a full rear wheel alignment must be performed after fitting to restore proper toe and camber settings. The SPF1922K covers both the left and right upper inner rear arm positions in a single kit. For comprehensive rear bushing renewal on any of the supported platforms, SuperPro offers additional individual kits covering the rear lower control arm, toe arm, trailing arm, and subframe mount positions - all of which share the same lifetime-warranty polyurethane construction.
