Belltech has built a reputation in the automotive industry for producing some of the best lowering kits available on the market. Belltech’s lowering kits are known for their ability to safely, effectively, and efficiently lower a truck.
Helping You Build A Better RideEach Belltech lowering kit, Belltech shock, and Belltech suspension system allows you to customize your truck so that it is ideally suited to your driving needs. It’s the perfect combination of form and function, so your vehicle can look good, stand firm, and deliver a high-quality ride every time.
The History of BelltechBelltech’s story is the perfect definition of the American dream. Over 35 years ago, a small company in Fresno, California, had an idea to build the “best performing” lowering suspensions for the Chevrolet pickup. Fresno had been a haven for lowered vehicles, and trucks were abundant there. Trucks of all kinds were being lowered; however, their suspensions were quite terrible and not roadworthy.
Springs were being replaced with new ones not meant for the application. At times, they were even cut and heated with torches at local muffler shops to achieve the lowered stance that was considered to be cool. While the result was an attractive stance, the ride quality was terrible, and comfort levels dropped dramatically.
Changing The Lowering GameBelltech had a better idea: build a spindle where the wheels are higher, but the rest of the front end geometrically remains the same. And that’s precisely what they did. Belltech came up with a spindle that launched the Sport truck craze in America.
Belltech’s success in the late 80s and 90s made it possible for the company to grow from a modest beginning to a larger manufacturing facility with a satellite warehouse. In 2015, the company expanded to its current 75,000-plus square-foot operation in Clovis, California. It allows them to cater to the increasing demands of the market.
