Yella Terra GM LS 25mm Alloy Valve Cover Spacer Kit — YT 5123
Yella Terra GM LS 25mm Alloy Valve Cover Spacer Kit — YT 5123
Yella Terra’s YT 5123 alloy valve-cover spacer kit creates additional rocker-arm clearance while retaining the original factory valve covers for an OEM-style appearance. The spacers incorporate scalloped sections around the inner cover rail where adjustable shaft rockers can otherwise contact the cover area.
Kit contents
- Pair of 25 mm alloy valve-cover spacers.
- O-ring seals.
- Coil relocation bracket.
- Extension adaptors for the factory valve-cover bolts.
LS application
- Designed for compatible LS1, LS2, LS3, LS7 and LSX-based engines.
- Extra clearancing of the spacer is required near the inlet rocker arm on LS3, L98 and LS7 applications.
- 25 mm spacer thickness.
- Allows retention of factory valve covers once the required rocker clearance has been established.
Fitment: Confirm rocker geometry, coil/bracket layout and required clearancing for the exact engine combination before installation.
