  • Whether driving surface streets or navigating tough off-road terrain, experienced Jeep owners recognize the importance of maintaining a proper balance in the suspension of their trucks. Plan your ideal weekend getaway in your truck. Perhaps you have loaded the bed with a couple of coolers, some beach chairs and maybe a fishing box. Next, hitch up a trailer to haul a boat or maybe a couple of jet skis. Take a look at the rear of your truck. Is it sagging down, maybe even further than the front part of the truck? Avoid ruining your truck, not to mention your valuable plans, by installing one of our truck suspension kits, which can provide the boost your truck needs to improve its hauling capacity.

    A Matter of Physics

    Though many models are designed with a standard amount of rake, or difference in height between the front and back of the truck, sometimes trucks need extra rake to properly carry weight. When weight pushes down on the back of the truck, the laws of physics operate to move the front upwards. Without appropriate rake, a Jeep’s suspension can be damaged by the weight of gear and trailers. At 4 Wheel Parts, we are confident that our wide selection of 3 inch lift blocks and u bolts can add the height you need to counteract the force of gravity and keep your suspension protected. For drivers with heavy-duty needs, we offer a range of 4 inch lift blocks with u bolts for even more height.

    Gone are the days when Jeep owners needed to hunt down the correct U bolt to match with their axles and suspension blocks. Our kits provide everything you need to boost your truck, complete with 4 inch lift blocks or 3 inch lift blocks and u-bolts. We are proud to offer expert advice for installation on any of the kits in our huge inventory, as well as competitive prices with a 100% price match guarantee. Give your truck wheels a break from weight that has been incorrectly balanced and preserve your suspension for your weekend getaways, whether you aim for the beach, mountains or the wide open road.
