Moker LS Alignment Tool Kit for GM LS Engines — Billet Aluminum Front/Rear Seal & Oil Pan Guide (4.8–6.0L)

The Moker LS Alignment Tool Kit precisely aligns the oil pan, front cover and rear main seal on GM LS engines to simplify seal replacement and ensure even sealing surfaces.

When replacing front or rear main seals on GM LS-family engines, correct alignment of the oil pan, front cover and rear cover is critical. The Moker kit provides purpose-built billet aluminum guides that replicate the oil pan and locate the front and rear covers so seals with Teflon inner lips sit true. That reduces the risk of seal damage during install and helps the engine assemble squarely for dependable operation.

How does this kit make replacing an LS front or rear seal easier?

The kit mimics the mating geometry of the oil pan and front cover, holding components in exact relation while you install seals and fasteners. Using the alignment pieces removes guesswork, letting one technician achieve factory-fit positioning without repeated mock-ups.

• Replaces the oil pan to hold correct vertical and lateral position during install.
• Holds front cover concentric to the crankshaft for correct seal fitment.
• Reduces risk of tearing Teflon inner sealing lips during assembly.

Which GM engines are compatible with this alignment tool kit?

The Moker kit was designed specifically around GM LS-series blocks and covers, covering a broad range from early LS1 through later LSA/LS9/LQ variants. Check your block casting and front cover style for fit, but the kit supports most common GM LS V8 applications.

• Fits LS1, LS2, LS3, LS6 and other early LS variants.
• Supports later engines including LSA, LS9, LQ4, LQ9 and L99 families.
• Works with 4.8, 5.3, 5.7 and 6.0 liter LS blocks.

What materials and construction features ensure accuracy and durability?

Each component in the set is CNC-machined from billet aluminum to tight tolerances so mating surfaces align repeatably. That rigidity prevents flexing under bolt torque and preserves alignment while seals are seated, making the tools suitable for frequent shop use.

• Billet aluminum construction for strength and dimensional stability.
• CNC-machined faces to match oil pan and cover interfaces precisely.
• Designed to resist deformation during multiple installations.

What comes in the kit and how is it used during assembly?

The kit includes three purpose pieces: an oil pan front cover alignment tool, a front cover billet alignment tool and a rear cover billet alignment tool. Install them in sequence during assembly to locate each cover to the block, then torque fasteners with the alignment tools holding the parts in position.

• 1x Oil pan front cover alignment tool — sets pan-to-block relation.
• 1x Front cover billet alignment tool — centers the front cover to the crankshaft.
• 1x Rear cover billet alignment tool — aligns rear main seal housing.

Who is this for: The Moker LS Alignment Tool Kit is aimed at professional mechanics, engine builders and experienced DIYers who service GM LS engines and want a reliable, repeatable method for installing front and rear main seals. If you frequently replace seals, rebuild LS blocks or install aftermarket covers, this kit reduces installation errors, protects delicate sealing lips and speeds up assembly without relying on trial-and-error alignment.
