Frequently Asked Questions About Kenworth T700 Leaf Springs, Hangers & Acc.
What year models of Kenworth T700 do these leaf springs fit?
Our leaf springs are designed to fit Kenworth T700 models from 2008 through 2019. However, there are variations between model years, particularly in spring eye dimensions and weight ratings. We recommend checking your existing spring's part number or contacting us with your VIN to ensure proper fitment. Early 2008-2010 models may have different bushing sizes compared to 2011+ models.
How difficult is it to replace leaf springs on a T700, and what tools do I need?
Replacing leaf springs requires moderate to advanced mechanical skills and typically takes 4-6 hours per side. Essential tools include a heavy-duty jack and stands rated for commercial trucks, spring compressors, impact wrenches, and torque wrenches capable of 450-500 ft-lbs. You'll also need proper safety equipment and ideally a helper. Many customers choose professional installation due to the heavy components and safety considerations involved.
What's the difference between OEM and aftermarket leaf springs for the T700?
OEM springs use factory specifications and materials, typically featuring shot-peened steel leaves with precise arch measurements. Quality aftermarket options often match or exceed OEM specs while costing 30-40% less. Key differences to look for include leaf thickness (usually 0.5" for standard applications), number of leaves (typically 3-5 depending on weight rating), and bushing quality. We carry both OEM-spec and upgraded heavy-duty options for various applications.
How do I know when my T700 leaf springs need replacement?
Common signs include visible cracks or breaks in the leaves, sagging that causes uneven ride height side-to-side, excessive bounce or harsh ride quality, and worn or damaged spring eyes. Also check for separated leaves, missing center bolts, or if your truck sits more than 2 inches lower than specification. Worn springs can affect tire wear, handling, and DOT compliance, so timely replacement is crucial.
What weight ratings are available, and how do I choose the right one?
T700 leaf springs typically range from 12,000 to 23,000 pounds per axle capacity. Your choice depends on your truck's configuration and typical loads. Check your door jamb sticker for GAWR (Gross Axle Weight Rating) specifications. For heavy haul or vocational applications, consider springs rated 10-15% above your regular loaded weight. Standard highway tractors typically use 12,000-14,000 lb front springs and 20,000-23,000 lb rear springs.
