      Improved Vehicle Performance. In case you have noticed excessive oil consumption, low acceleration power and occasional gray or white smoke from your Jeep, you need to get this Oversized Piston Ring Set - 0.030. The rings are not only designed for perfect OE replacement, but also to restore your Jeep's cylinder compression. Furthermore, this set of piston rings prevent crankcase oil from entering into the combustion chamber, causing the engine to burn oil instead of just fuel.

      Superior, Durable Construction. Manufacturer forges this piston ring set from high-grade steel for a durable construction. The steel material undergoes tempering to ensure the rings maintain a stable size throughout their thermal cycle in the engine. They are also designed and measured with precision to ensure that they correctly fit your Jeep's 3" oversized cylinder bores.

      Professional Installation Recommended. Although this Oversized Piston Ring Set is manufactured for direct-fit installation, professional mechanical expertise is paramount. Before installing the piston rings, your Jeep's engine must be disassembled first. Even so, the process can be completed in roughly six hours using common garage tools.

      Warranty. Manufacturer has outdone itself as far as manufacturing superior-quality Jeep parts is concerned. What's more, the manufacturer backs all its products with a limited warranty meant to last for either one year or 12,000 miles. Warranty exclusions may apply in case of misapplication, misuse, neglect or improper installation.

      Application. This Oversized Piston Ring Set - 0.030 is manufactured for all 1997-2006 4.0L Jeep Wrangler TJ models.
