Turnbuckles
Fit all truck models
General Instructions
Screw locking nut onto threaded hook.1.
Screw threaded hook into threaded end of
2.
turnbuckle barrel.
HAND TIGHTEN -- If it is necessary to
3.
use a wrench be extremely careful no to
over-tighten. Over-tightening will damage
the truck bed (see below for specific
tightening instructions).
Install turnbuckles with threaded hook up.
4.
This prevents water from accumulating in
the barrel.
CAUTION: DO NOT OVER-TIGHTEN --
Damage may result from over-tightened
turnbuckles.
FM-TBS: Spring-loaded (installed in front) - 10"
barrel with 11" hook (15" - 22" reach)
Holding the turnbuckle by the
1.
non-threaded hook, mark a line on the
hook where it enters the barrel.
Hand tighten until the line pulls away from
2.
barrel 1/4 inch. This pre-loads the spring
to approximately 300 lbs. -- enough to
provide good handling yet allow an
additional 500 lbs. of tension to absorb
shock. DO NOT OVERTIGHTEN -- spring
will bottom out at 3/4 inch and all shock
absorbing capability will be lost.
Tighten jam nut.3.
FM-TBR: Stress-guard (installed in rear) - 8"
barrel with 24" hook (21" - 33.5" reach)
Hand tighten just until internal rubber
1.
damper is felt to slightly compress.
