Before operating vehicle off-road, test for proper bump
stop operation by fully cycling the suspension and check-
ing for obstructions. Add, remove or replace BumpStop
Spacers if necessary until maximum unobstructed suspen-
sion compression is achieved.
Operation
Future BumpStop length adjustments should be made with
NO LOAD on the coil springs, and the suspension at FULL
DROOP.
Depending on the springs used, it may be necessary to
spread the coils apart when inserting or removing the 2.00”
BumpStop Spacer (A).
Maintenance
Regular cleaning with pressurized water is recommended
to maximize ease of operation and reliability.
