Previously, the inner diameter would bend when being pressed, applying too much pressure to the valve guide replacement.
(This is especially the case in RB26 models)
NAPREC valve guides handle heavy pressure very well.
After a press-fit, there is no need to correct the inner diameter.
The shape of the combination valve guide comes from our extensive experience with processing high performance engines.
Since the material is far stronger than Phosphor Bronze, the combinations valve guide is much more abrasion-resistant.
