We offer a variety
of different sized Case Saver Inserts to meet all needs. Case Saver Inserts are
a must when rebuilding your VW engine case. Most times you will find the original
threads in the engine case have been pulled out. Installing Case Saver Inserts
repairs the damaged threads and replaces the old weak threads so you won’t have
studs pulling out down the road.
