Frequently Asked Questions About GMC General Truck Leaf Springs, Hangers & Acc.
What years and models of GMC General trucks do these leaf springs fit?
Our GMC General truck leaf springs are designed to fit models from 1977 through 1996. However, compatibility can vary based on factors like wheelbase length, cab configuration, and whether your truck has single or tandem axles. We recommend checking your truck's VIN and specifications before ordering, or contact our support team with your truck's details for exact fitment confirmation.
Are these leaf springs heavy-duty enough for commercial hauling applications?
Yes, we carry both standard and heavy-duty leaf spring options for GMC General trucks. Our heavy-duty springs are typically rated between 5,000 to 12,000 pounds per spring, depending on the model. For commercial hauling, we recommend springs with higher arch and additional leaves. Always match your spring capacity to your truck's GVWR and typical load requirements to ensure safe operation and optimal ride quality.
What tools and experience level are needed to install leaf springs and hangers?
Installing leaf springs requires intermediate to advanced mechanical skills and proper equipment. Essential tools include a floor jack, jack stands rated for commercial trucks, spring compressors, impact wrenches, and torque wrenches. The job typically takes 4-6 hours per axle. Safety is critical due to the high spring tension. Many customers choose professional installation, which usually costs between $400-800 depending on your location and the complexity of the job.
What's the difference between OEM-style and aftermarket leaf springs for GMC General trucks?
OEM-style springs match original factory specifications for ride height and load capacity, making them ideal for maintaining stock performance. Aftermarket options often feature improved steel alloys, better corrosion resistance, and may offer enhanced load capacity or different ride heights. Our aftermarket springs typically include greaseable bushings and improved shackle designs, while OEM-style springs may use rubber bushings. Both meet or exceed original safety standards.
How do I know when my leaf springs and hangers need replacement?
Common signs include sagging ride height (truck sits lower than normal), cracked or broken leaves visible during inspection, excessive squeaking or clunking noises, uneven tire wear, and poor handling or swaying. Check for rust perforation on hangers and excessive wear in bushings or shackle pins. If your truck leans to one side or you notice more than 2 inches of sag compared to original ride height, replacement is typically necessary for safety and proper load handling.
