Piston Ring Set for the 5.0L V8 AJ133 petrol engine, supplied at standard bore size.

The ring pack seals the combustion chamber against the cylinder bore, controls the oil film left on the bore wall, and transfers combustion heat from the piston crown into the block. It is renewed whenever the pistons are withdrawn, the bores are honed, or the engine is rebuilt.

One set covers a single piston. Eight sets are required for a complete engine.

Frequently asked questions

What is the AJ133 piston ring set and what does it do?
The piston ring set seals the combustion chamber against the cylinder bore on the 5.0L V8 AJ133 petrol engine, controls the oil film on the bore wall and transfers heat from the piston crown into the block. Supplied at standard bore size.
How many sets are needed for a full engine rebuild?
One set covers a single piston, so eight sets are required for a complete 5.0L V8 AJ133 engine. Order the correct quantity for the job, whether replacing rings on one piston or rebuilding the whole engine.
When should the piston rings be replaced?
Replace the piston rings whenever the pistons are withdrawn, the bores are honed, or the engine is rebuilt. Worn rings on the AJ133 V8 typically show as blue exhaust smoke, high oil consumption and lost compression.
This is standard bore size, what does that mean for ordering?
Standard size suits an engine at its original bore diameter. If the block has been rebored oversize, this standard set will not seal correctly. Confirm the bore has not been machined oversize before ordering.
