A Better Service :

SPR fully appreciates that the longer an engine remains inactive during overhaul or repair, the greater the impact on revenue. Rapid sourcing of quality spares reduces expensive down time.

Same day despatch of stock items from SPR's extensive warehouse on orders received before 15.00 hrs (GMT) is standard. After this time, despatch will normally take place within 24 hours.

For replacement rings, engineers continually rely on SPR to deliver - wherever they are in the world.
