The 8-leaf uprated rear spring strengthens the rear suspension for Austin Healey BN4–BJ8 models, offering approximately 12% increased stiffness compared to the standard spring design. This extra support improves load handling, reduces rear-end sag under spirited driving, and enhances stability during cornering — all without sacrificing everyday ride comfort.
Ideal for rally events, fast road use, or touring with passengers and luggage, this uprated spring fits directly with no modifications needed.
