SL Series Suspension and Intake Components

Polyurethane, printed and machined parts for Toyota and Lexus platforms

SL0002 rear subframe rear bush assembly, exploded render — SL0002 rear subframe rear bush assembly

Scope

Replacement parts designed around worn or unavailable OEM components: rear subframe bushes for the XE10 family, differential mount bushes and an intake adapter.

What I did

Modelled each part from the OEM bore, cup or flange it has to fit, and verified it against a donor before a batch.
Chose material for the duty: cast polyurethane or TPU 95A for compliance and NVH, aluminium sleeves for bolt clamp, PA6-CF or ASA for under bonnet heat and vibration.
Released each part with a bill of materials, a landed cost and a QC check on every unit.

Result

One subframe bush design covers twelve chassis codes across Toyota and Lexus, which is what makes the tooling and the batch worth doing.
