Firestone’s Loadshare TM air helper springs improve the
ride quality on both conventional and cabover trucks.
Ideal for use on refuse compactors, utility trucks,
snowplows, buses, concrete mixers, dump trucks and
trucks equipped with lift axles. Or just about any truck
that has constantly changing loads that effect the front
end of the vehicle.
Universal mounting kits are used to install Loadshare
air helper springs on most class 6, 7 and 8 front
suspensions. Adaptations may be required due to
various engine and driveline combinations. Designed
for straight chassis and highway trucks, including:
Kenworth Ford
Mack Volvo White GMC
Navistar Western Star
Freightliner

air helper springs:
Reduces leaf spring fatigue and tire wear.
Installs quickly on your current suspension.
Maintains proper ride height.
Reduces front end dive while braking.
Improve ride quality.
Reduce the chance of cargo damage.
Loadshare Requirements:
A 5-1/4” clearance radius (measured from spring pack
center bolt) is required for all Loadshare air helper
springs. When installing Loadshare air helper springs
make certain that steering arms, shock absorbers,
brackets, oil filters, etc., do not intrude into this area.
The Loadshare kit is intended for use on primary front
suspensions which have 3-1/2” or 4” leaf spring widths.
Basic Kit:
Each Loadshare kit comes with: two air helper springs,
mounting hardware, airline, and step by step installation
instructions. Plus, an in cab air regulator panel and gauge
that connects to your existing air supply.
Loadshare air helper springs decrease maintenance
and repair costs to both suspension and drivetrain,
keeping the truck out on the road - making money.

Footnote Chart
Notice: Firestone has made every attempt to assure that the air helper spring kits listed will properly fit. Chassis modifications made by others that effect suspension dimensions
may not provide conditions for proper fit. Due to new model introductions and manufacturer changes, Firestone reserves the right to make changes to the list without notification.
Note: Some vehicle manufacturers use brake proportioning valves to adjust braking force as a function of frame to axle distance. If you modify your suspension it effects the function
of this valve. We suggest that you check with your dealer on proper treatment of this device prior to installation of the air helper spring kits.
