CUSCO Formula Link Jr. Adjustable Rear Lower 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 Lower Control Arm Set replaces the factory lower links in the Toyota AE86 rear 4-link suspension with adjustable steel arms. The +7 mm to -5 mm adjustment range allows rear lower-link length to be fine-tuned for modified suspension setups and performance-oriented AE86 builds.

Each arm uses CUSCO's hybrid Formula Link Jr. configuration, combining a metal rod-end pillowball at one end with a hard-rubber bushing at the opposite end. This provides a more direct suspension connection at the pillowball side while retaining a rubber-bushed mounting point at the other end.

The set installs as a direct bolt-on replacement for the factory rear lower control arms and includes both left- and right-side links.

Key Features

  • Adjustable rear lower control arm set for Toyota AE86
  • +7 mm to -5 mm length adjustment range
  • Metal rod-end pillowball at one end
  • Hard-rubber bushing at the opposite end
  • Steel control arm construction
  • Designed for the AE86 solid-axle rear 4-link suspension
  • Direct OE-replacement bolt-on design
  • Supplied as a matched pair
  • Suitable for fine-tuning rear lower-link length in adjustable suspension setups

Formula Link Jr. Hybrid Joint Design

Formula Link Jr. combines two different joint styles within each control arm. The metal rod-end pillowball reduces movement at one mounting point, while the hard-rubber bushing at the opposite end retains a rubber-isolated connection.

This configuration provides an intermediate option between CUSCO's fixed rubber-bushed rear links and full Formula Link arms that use metal rod-end pillowballs at both ends.

Series Overview

Formula Link is the fully adjustable option. Pillowball rod ends at both ends eliminate rubber-bushing compliance and provide the widest adjustment range of the three series.

Formula Link Jr. combines one pillowball rod end with one hard-rubber bushing in each arm, providing adjustable link length while retaining some isolation at one mounting point.

N1 Link uses hard-rubber bushings at both ends and a fixed link length. It retains more isolation than either adjustable series and does not require suspension-link length adjustment.
