Highly recommended upgrade for Mk3 to Mk5 Tvan.
 
These assist the coil spring before the axle enters the bump zone (bigger bumps) and smoothly arrests axle travel before it damages your shock, upper shock mount or worse; bends an axle and/or asymmetric link.
 
Your factory bump stop (chassis mounted) is effective with small impacts but only offers limited protection, this is especially true for the left axle.
 
Note - These are not necessary for vans already fitted with Track's - 33" Bump Stop
Note - The fitment of this product does require removal of your coil spring and threading of the upper spring seat (boss already installed)
