2.5" Lift Coilover - Bypass System
Manufacturer description: 08-10 FORD F250/350 4X4 DIESEL 2.5" LIFT COILOVER-BYPASS SYSTEM
From Carli Suspension
For those unfamiliar, a bypass shock has external tubes with one-way check valves that are fully adjustable to allow users to tailor the amount of fluid that bypasses the piston/valving on either the compression or rebound stroke within the effective range of the bypass tube. Typically, there will be a tube surrounding the compression zone at ride height that will allow fluid to freely move around the piston giving a supple ride. Once a large hit is encountered, the piston will move upward closing off the port, thereby forcing all fluid through the valving which substantially increases the shock’s resistance in this secondary zone.
The truck will sit 2.5” higher in the front and have more wheel travel thanks to the Coilovers. Stainless Brake Lines and an Adjustable Track Bar round off the front end geometry correction while Caster Shims improve on the stock handling. The rear is outfitted with a block eliminating Full Progressive Spring Pack lifting it 2” requiring no block to achieve proper ride height in the rear. The result is extended travel and a softer ride while wheel hop/axle wrap are minimized at the cost of 15% less load capacity than a stock F250.
