AE86 CUSCO N1 Link Rear Upper Control Arm Set

For 1983–1987 Toyota Corolla AE86.

Overview

The CUSCO N1 Link Rear Upper Control Arm Set is a fixed-length replacement for the rear upper links on 1983–1987 Toyota Corolla AE86 applications. Each steel arm uses hard-rubber bushings at both ends, making this set a straightforward choice for owners who want rubber-bushed links rather than adjustable pillowball arms.

The pair replaces both upper links in the factory solid-rear-axle four-link suspension. Choose N1 when fixed link length suits your build; choose an adjustable series when your suspension setup requires link-length adjustment.

Key Features

  • Fixed-length rear upper control arm pair
  • Hard-rubber bushings at both ends of each arm
  • Steel construction
  • Replaces both factory rear upper suspension links
  • Uses the factory chassis and rear-axle upper-link mounting locations
  • Designed for the AE86 solid-rear-axle four-link suspension
  • No suspension-link length adjustment required

Which CUSCO Rear Control Arms Should You Choose?

These three CUSCO steel rear-link series offer different combinations of length adjustment and joint design. Upper and lower sets are sold separately; check each product's applications before choosing parts for your car.

Formula Link — Best for builds needing the widest adjustment range of these three series

Choose Formula Link when your suspension setup needs more link-length adjustment and you want pillowball joints at both ends. Its +20 mm to -10 mm range offers more adjustment than Formula Link Jr., with no rubber-bushed connection in either arm.

Formula Link Jr. — Best for fine-tuning link length within a smaller adjustment range

Choose Formula Link Jr. when your suspension setup needs a smaller link-length correction within its +7 mm to -5 mm range. Each arm combines one pillowball joint with one hard-rubber bushing rather than using pillowball joints at both ends.

N1 Link — Best for replacing fixed-length rear links without adding length adjustment

Choose N1 when you do not need link-length adjustment and prefer hard-rubber bushings at both mounting points. The fixed-length design avoids choosing an adjustment setting; it is not an alternative to an adjustable arm when geometry changes require one.

Our Recommendation: Choose N1 for a fixed-length replacement with hard-rubber bushings at both ends. Choose Formula Link Jr. when its smaller adjustment range and mixed joints meet your setup needs, or Formula Link when you need the wider adjustment range and pillowball joints at both ends. Ride comfort and vibration also depend on the rest of your suspension setup.
