Low speed bleed is too small to soften the LS compression

Low speed bleed is increased and a longer tapered needle is installed to double the LS adjustment range

Generically valved to best compromise all leverage curves

Revalve with Midvalve style 2 stage custom shimmed for leverage and type of riding.

Generically valved to best compromise all spring rates

Revalve with 2 stage custom shimmed for stroke and spring rate.

Uses belleville washers that snap over to open on high speed hits, creates no progression in high speed valving, i.e. blows through the stroke to easily

Replaced with high speed tapered shim valve stack to prevent bottoming but allow for blow-off on square edged high speed hits

Standard Buna o-ring with high friction urethane grip dust seal

Double lip Viton oil seal, oil wiper barrier and mud and dust scraper system

squats outwardly with no constraint, no ramp-up resistance

Shape factor, ramps-up progressively as it conforms and fills the shape of the spring inner diameter

5/8" vs 1/2"

Modify internals to accommodate more flow

stiff adjuster spring rim loads shim stack, creates too much mid speed damping

Change piston design to be a shimmed blow-off valve, increasing high speed compression is now independent of mid speed damping

Reservoir pressure assisted end of stroke position sensitive compression pop it valve

Replace with the SSD speed sensitive custom valved shimmed four port piston valve, prevents bottoming without high speed harshness

Generically valved to work with over stiff propedal

Revalve with Midvalve style 2 stage custom shimmed for leverage and type of riding.

Generically valve to best compromise all spring rates

Revalve with 2 stage custom shimmed for stoke and spring rate.

Low speed bleed is too small to soften the LS compression

Low speed bleed is increased and a longer tapered needle is installed to double the LS adjustment range

squats outwardly with no constraint, no ramp-up resistance

Shape factor, ramps-up progressively as it conforms and fills the shape of the spring inner diameter

As pressure increases in the reservoir the valve gets stiffer

Replace with the SSD speed sensitive custom valved shimmed four port piston valve, prevents bottoming without high speed harshness

Too much reservoir pressure force on valve creates low to mid speed harshness when increased

Remove Propedal and replace with low speed adjuster needle and SSD valve.

Revalve with 2 stage custom shimmed for stroke and spring rate.

Propedal valve only provides high speed damping

Use the Propedal knob to control the newly installed low speed needle to provide low speed adjustment, 15 clicks

Pressure can ramp-up to nearly 1500 psi, this is what controls the boost valve!

Modified reservoir reduces pressure ramp-up to under 400 psi, extended reservoir keeps it around 200 psi
