Yes, we always recommend checking the wheel alignment after replacing a spring to avoid any unnecessary tyre wear. I am going to mount a Hengtong spring and the diameter at both ends is the same, but the spring is more closely coiled at one end. Which end should be up and which one down? The performance of the spring will be the same whichever way it is mounted, however we always recommend springs are installed with the more closely coiled end to the top to avoid road debris, e.g. gravel, getting between the tighter coils. Why do you recommend replacing springs in pairs, although it might be only one spring broken? When only 1 spring is replaced across an axle, the life expectancy of the other spring will decrease and the car may be imbalanced. Failure to replace springs in axle pairs can lead to an uneven ride height, less responsive steering, less secure road holding, increased braking distance, increased tyre wear and increased fuel consumption.     Our factory                              Spring type Explanation for spring design C  =  Cylindrical end U  =  Widened end I  =  Pigtail end K  =  Conical spring Coil Spring Manufacturing           Contact information   Yutian Hengtong Spring Shock Absorber Co.,Ltd Address:Xingyu Industrial Park Region of Yutian County of Tangshan, Hebei Province , P.R.C Tel: +86-315-6106835  Fax: +86-315-6162286 Skype:hengtongth07  QQ:3215762938 Web:  http://www.facebook.com/htautospring E-mail:fanfan(at)zghtth.cn
