WHAT VANS SHOULD GET A STAGE 4 KIT?
- This kit is designed for heavily loaded vans that are looking for improved stability, a better ride and reduced suspension sag. We tune each set of Fox shocks we sell to your van weight prior to shipping. We will be contacting you for weights and the driving conditions the van is put through.
When your are lifting or upgrading your sprinter suspension for a better ride there is no better option than the Bilstein B6 front strut. Bilstein B6 struts utilize a unique, velocity sensitive, digressive piston which reacts to changing road conditions. All B6 struts are tuned to assure optimal performance is achieved. Bilstein B6 struts offer a significant improvement in ride quality, handling, and comfort.
The front Sumo Spring replaces the hard factory bump stop It contacts the control arm at ride height to increase the front suspension spring rate, while still compressing to the height of the factory bump stop. Suspension travel is not reduced. The additional spring rate reduces sway, improves control in high winds and comfort while the suspension cycles. Larger rear sumo spring bump stops bump up the rear spring rate for vans that are loaded to the GVWR. These larger bump stops reduce rear end sag when loaded and provided more stability.
The custom tuned Fox shocks smooth out the harshness experienced on washboard roads and sharp, abrupt impacts. The bounce experienced over large bumps is reduced and the side to side sway over uneven surfaces is minimized.
*** We tune each set of shocks specifically for your application. Please allow for shock tuning time after your order is placed ***
