• Replaces all 15 rocker cover fasteners. Direct replacement for Isuzu PN 0-28650-630-0.
• Titanium burnt blue finish. Heat-resistant, and it stands out against a plain engine bay.
• Anodised washers. Corrosion resistant and colour-fast, in your choice of colour.
• Machined spacers included. 15 of them, one per bolt.
• Suits HPD alloy covers and factory covers. Same bolt pattern either way.
• Cosmetic. It secures the rocker cover exactly like the factory hardware does. It does not add power.

• Isuzu D-MAX. 2014 onwards, Euro 4 4JJ1 and 4JJ3.
• Isuzu MU-X. 2014 onwards, Euro 4 4JJ1 and 4JJ3.
• Mazda BT-50. 2020 onwards, 4JJ3.
• The cover is what matters. Suits rocker covers with 4 bolts across the front and 15 bolts in total, which is typically the late Euro 4 4JJ1 and all 4JJ3 engines.

Check the number and layout of the bolts on your cover before ordering. This kit is for the 4-bolt front, 15 bolt total cover. Earlier Euro 2 and Euro 3 4JJ1 covers have 3 bolts across the front and 14 in total, and they need the 4JJ1 Ti Burnt Blue Bolts, Euro 2 and 3 instead. The two kits do not swap over.

• 15 x HPD titanium burnt blue bolts.
• 15 x HPD anodised washers. Choice of colour.
• 15 x precision-machined spacers.

Washer colours commonly available are black, blue, red, gold, purple and green. Availability varies, so select your preferred colour if options are shown on this page, or leave a note at checkout and we will sort it out with you.

This is a cosmetic hardware kit. It secures the rocker cover, it looks good doing it, and that is all it does. No power, no efficiency, no change to how the engine runs.

Count the bolts on your own cover before you order. The 2014 changeover on the D-MAX and MU-X is where people get caught, and a 14-bolt cover will not take this kit.

Q: How many bolts are in the set?

A: 15 bolts, 15 anodised washers and 15 machined spacers.

Q: Will these bolts fit my 4JJ1?

A: Yes, if it is a late Euro 4 cover with 15 bolts total and 4 across the front. Check the layout before you order. An earlier Euro 2 or Euro 3 cover has 3 across the front and 14 total, and needs the other kit.

Q: Do they fit the 4JJ3?

A: Yes. Direct fit for all 4JJ3 engines, including the D-MAX, MU-X and the 2020 onwards BT-50.

Q: Can I use them on an HPD aluminium rocker cover?

A: Yes. They suit HPD aluminium covers and factory covers.

Q: What colours are available?

A: Washers are commonly available in black, blue, red, gold, purple and green. Availability varies, so ask if you need a colour confirmed.

Q: What is the Isuzu part number these replace?

A: 0-28650-630-0.

Q: Do they make any difference to performance?

A: None at all. They are rocker cover bolts with a good finish.
