BigBore Rear Spring, model accessory, 2/4WD

This BigBore rear spring is a model accessory for 2WD and 4WD applications and is intended for use with BigBore aeration dampers. Its dedicated rear position gives model builders a clearly defined suspension component for replacement, maintenance or setup changes on compatible chassis. Because the part is specified as a rear spring, it addresses one exact area of the suspension rather than a broad, undefined fitment. The BigBore aeration damper reference also narrows the component match to a known damper type, which helps when planning service work or keeping spares organised at the bench. In running setups, rear suspension changes can be made with a component chosen for that axle position instead of adapting a general-purpose part. The 2WD and 4WD compatibility note broadens its use across different drivetrain layouts where BigBore aeration dampers are fitted. This spring suits routine rebuilds, worn-part replacement and chassis tuning sessions where the rear damper setup is being reviewed. It also fits neatly into a parts collection for model maintenance, with a specific function that is easy to identify when preparing compatible suspension assemblies.
