AE86 CUSCO N1 Link Rear Lower Control Arm Set (1983-87 Corolla)

CUSCO N1 Link Rear Lower Control Arm Set

For 1983–1987 Toyota Corolla AE86.

Overview

The CUSCO N1 Link Rear Lower Control Arm Set replaces both rear lower links on 1983–1987 Toyota Corolla AE86 Trueno and Levin models, 1985–1987 U.S.-market GT-S models, and 1984–1987 U.S.-market SR5 models. Each steel arm has a fixed length and hard-rubber bushings at both ends for the factory solid-rear-axle four-link suspension.

This complete, pre-bushed pair suits an owner refreshing worn lower links while keeping fixed suspension-link geometry. It replaces the arm assemblies rather than requiring replacement bushings to be pressed into the original arms, and it does not provide the length adjustment of the Formula Link series.

Key Features

• Complete rear lower pair replaces the left and right longitudinal lower links.
• Hard-rubber bushings at both ends retain rubber-bushed mounting points throughout each arm.
• Fixed-length steel construction retains a nonadjustable lower-link layout.
• Factory mounting locations suit the original AE86 rear four-link suspension.
• Pre-installed bushings provide complete replacement assemblies rather than a bushing-only service kit.

Which Rear Control Arm Should You Choose?

N1 Link — Best for refreshing worn links while retaining fixed geometry

Choose N1 when you want complete replacement arms with installed rubber bushings and do not need to change link length. Both ends remain rubber-bushed, unlike the adjustable alternatives.

Formula Link Jr. — Best for small link-length changes while retaining a rubber-bushed connection

Choose the CUSCO Formula Link Jr. rear lower control arms when your suspension setup needs modest length adjustment. Each arm combines one pillowball rod end with one hard-rubber bushing and offers +7 mm to −5 mm adjustment.

Formula Link — Best for a suspension setup needing a wider adjustment range

Choose the CUSCO Formula Link rear lower control arms when the required length change exceeds the Jr. range. Its +20 mm to −10 mm range and pillowball rod ends at both ends provide an adjustable link without rubber-bushed joints.

All three series use steel construction and have separate rear upper and rear lower pairs. Upper-link adjustment changes upper-link geometry and can be used in pinion-angle setup; lower-link adjustment changes the longitudinal link geometry. The N1 versions remain fixed in both positions. The upper and lower sets are separate purchases.

Our Recommendation: Choose N1 for a complete fixed-length lower-link refresh. Choose Formula Link Jr. when your setup needs a small length change and you want to retain one rubber-bushed joint, or Formula Link when the wider adjustment range is needed. An adjustable arm is not necessary simply to replace worn fixed-length links.

Matching Rear Upper Control Arms

For a matching four-link refresh, the CUSCO N1 Link rear upper control arm set replaces the two upper links with the same fixed-length, hard-rubber-bushed design. The upper pair is sold separately.
