If you want to avoid visiting car workshops to increase the ground clearance of your vehicle for off-road riding, nothing can be as good as the spacer lift kits, and they come at a comparatively lower price than those workshops will charge you.  But these kits have a limitation; they won't allow you to raise your vehicle more than a few inches. Hence, spacer kits are your ideal option if you don't care much about the off-road performance that you usually get by increasing ground clearance.
