What is the difference between Bilstein B4 and B6?
2 Answers
b4 and b6 differences, here are the specific details: Differences: b4 is an OEM model, approximately equivalent to factory performance. b6 is stiffer with unchanged height and can be paired with factory springs. Other types: b8 is not only stiffer but also shortened, requiring short springs. b12 is a set consisting of b8 paired with short springs. b14 is a threaded shock absorber with adjustable height. b16 is a threaded shock absorber with adjustable height and damping. Introduction: Bilstein was founded in 1954. As a renowned shock absorber manufacturer with 65 years of history, Bilstein has always been famous for its high quality and performance. Meanwhile, Bilstein is also willing to authorize its professional knowledge to selected automotive companies. As a partner for seminars, training centers, tuning experts, and dealers, Bilstein provides training programs suitable for each target group.
I've been driving for almost 20 years and love studying car components. Both Bilstein B4 and B6 are shock absorbers, but they differ significantly. The B4 is an OEM replacement model, offering strong comfort after installation, smooth rides on bumpy roads, and is ideal for daily commutes or city driving. It also has a long lifespan and is simple and affordable to replace. The B6 is a sportier upgrade, with much stiffer damping, excellent cornering support, and stable body control on mountain roads or during high-speed lane changes, significantly enhancing handling. However, it can be a bit bumpy and works best when paired with springs, plus it's considerably more expensive than the B4. Personally, I think the B4 is more hassle-free and cost-effective if you're not into modifications. But if you're after driving excitement or frequently tackle rough roads, the B6 is worth the investment.
