AE86 CUSCO Formula Link Jr. Adjustable Rear Upper Control Arm Set
For 1983–1987 Toyota Corolla AE86 Trueno / Levin, 1985–1987 U.S.-Market Corolla Sport AE86 (GT-S), and 1984–1987 U.S.-Market Corolla Sport AE86 (SR5)
Overview
The CUSCO Formula Link Jr. Adjustable Rear Upper Control Arm Set replaces the factory fixed-length upper links in the AE86 rear four-link suspension with an adjustable hybrid-joint design. Each arm uses a metal pillowball rod end at one mounting point and a heavy-duty rubber bushing at the opposite end, combining an adjustable upper link with one rubber-bushed connection per arm.
Each arm provides a +7 mm to -5 mm adjustment range and installs at the factory rear upper-control-arm mounting locations used by the listed JDM AE86, U.S.-market GT-S, and U.S.-market SR5 applications.
Key Features
- Adjustable rear upper control arm pair
- +7 mm to -5 mm length adjustment range
- Metal pillowball rod end at one end of each arm
- Heavy-duty rubber bushing at the opposite end
- Steel construction
- Replaces both factory rear upper suspension links
- Uses the factory chassis and rear-axle mounting locations
- Designed for the AE86 solid-rear-axle four-link suspension
Hybrid Pillowball & Rubber-Bushing Design
Formula Link Jr. combines a pillowball rod end with a heavy-duty rubber bushing in each upper link. This retains one rubber-bushed mounting point while still providing adjustable upper-link length for suspension setup and pinion-angle correction.
