If you want a tidy improvement in vehicle response, the Serpent 903599 solid rear axle delivers a compact, durable solution. Built from hardened spring steel, it aims to reduce rotating mass while holding up to regular use. It installs as a drop-in swap so you can test handling changes without heavy modification.
Adopting a solid rear axle reduces unsprung components and rotational inertia, which helps the car accelerate and respond more promptly to throttle inputs. The simpler mass distribution can also make the rear end more predictable on mixed surfaces and during quick direction changes.
Well suited to tuners and racers testing lightweight changes, this solid rear axle balances durability and performance for regular club or track use.
