I would venture to guess no, unless Bilstein is willing to do it for owners at a later time. Toyota will not rebuild them, we'll just replace them with new units.
Please contact BILSTEIN Off-Road Department direct at 1-800-537-1085 for parts, service or technical questions.
OWNER REBUILDABLE SHOCKS
(9300/9200/8125/7100 Series)
The 9300 Series, 9200 Series, 8125 Series and 7100 Series are fully owner rebuildable and revalvable. Any component can be purchased through a BILSTEIN dealer or direct from BILSTEIN. Owner rebuildable shocks can also be revalved and serviced by BILSTEIN, if requested.
FACTORY REBUILDABLE SHOCKS
(7100 Classic/6112/5165/5160/5125/5100 Series)
Factory rebuildable shocks can be serviced by the BILSTEIN Technical Center in Poway, California. These shocks can be rebuilt to factory specification or revalved to a new specification. Internal adjustments can be made independently to the rebound and compression damping forces.
