Tamiya CW-01 Front Lower Arm Upgrade with Integrated Spring Mount JR-LB02-BK by Jazrider  [JR-LB02-BK]

CW-01 front lower arm replacement

This aluminium front lower arm is made to replace the stock plastic unit on Tamiya CW-01 based kits such as The Hornet and Grasshopper. Machined from solid aluminum, it includes a built-in spring mount so it mates with the original front suspension layout without altering factory geometry.

Fitment is limited to the listed Tamiya CW-01 platforms. This aftermarket hop-up increases stiffness and wear resistance versus the injection-molded arm, providing a stable mounting surface for the lower link and spring while maintaining the usual servo and steering linkage clearances for the CW-01 layout.

Installation notes: the arm uses the same mounting points as the factory lower arm and accepts standard CW-01 ball studs and hinge pins. During installation verify retention clips and steering knuckle clearance to prevent binding. Apply thread locker to metal-to-metal fasteners when needed and recheck spring mount seating after the first session to confirm preload and alignment.

Tuning role: replacing the plastic arm with aluminum reduces front flex and gives a firmer feel at the contact patch. Expect altered response through corners that may require complementary changes to spring rates, damper settings, or anti-roll adjustments on CW-01 cars.

Select this aluminum front lower arm when you want a direct, durable swap for CW-01 front suspension that preserves factory geometry and supports progressive front-end tuning.
