To improve the factory ride quality, our donor truck's owner purchased two Rancho RS 9000XL adjustable shock absorbers from ORU and had them installed while the truck was on the lift. During this process, ORU's technician noticed an area where a lack of clearance might have prevented operation of the shock adjustment knob. The area in question was near the lower shock mount. To resolve the issue, ORU simply ground a small clearance opening that would allow easy access to the adjustment knob. The modification did not affect the strength of the lower shock mount.
