The Timbren PF357 is a helper spring kit: Rubber Spring; Frame Mount; 20,000 Pound Weight Capacity Per Set (Not To Exceed The Gross Vehicle Weight Of The Vehicle); AEON Hollow Rubber.
This SES Suspension Upgrade can be adapted to fit the front suspension of a heavy-duty Peterbilt 338/357/359 series chassis equipped with leaf springs. Each laser cut piece of steel is precision bent and powder-coated to ensure a quality fit. We’ve engineered our hollow rubber springs to deliver a progressive spring rate. In other words, the more weight that pushes down on the rubber springs the harder they work to prevent rear end sag, and help stabilize the load.
Features
- Eliminate Vehicle Squatting And Sagging
- Cushion Road Shocks
- Improves Handling
- Limited Lifetime Warranty
