Novak's engine mounts for the Jeep TJ & LJ Wranglers provide great strength and a precise GM Gen V V8 engine installation.

Weld-In Version, Replacing I4 & I6 Frame Brackets

Kit contents:

• Frame platform sets
• Upper HNBR isolators
• Lower HNBR isolators
• Engine block plates
• Fastening hardware
• Instructions

This version of our TJ / LJ mount is for GM Gen V (LT series) V8 engines, entirely replacing the existing Jeep I4 or I6 frame mount.

Removal of the factory frame mounts for both 2.5L I4 and 4.0L I6 engine Wranglers is required. This is best done with a separating disc, plasma cutter, torch, or reciprocating saw, followed up by a grinder or flap-wheel.

Bolt-In Version, Replacing I6 Engines

Kit contents:

• Frame platform sets
• Upper HNBR isolators
• Lower HNBR isolators
• Engine block plates
• Fastening hardware
• Instructions

This version of our mount allows you to retain your 4.0L I6 engine frame horns when using a GM Gen V (LT series) engine. Trimming of these factory frame horns is required, then they will be bolted through the top then drilled and bolted or optionally plug-welded at the flanks.

Features

Ease of Installation

These mounts are available in either weld-in style or bolt-in style. Detailed instructions will guide to an ideal installation.

Strength

The Novak mounts feature thick 3/16" laser cut and CNC bent steel construction. Engineered using a welded box design geometry to provide maximum strength and assure that they will survive even the wildest V8's.

Vibration Isolation

Each mount kit comes with our HNBR (Hydrogenated Nitrile Butadiene Rubber) isolators — the latest refinement in Novak’s ongoing material development. HNBR delivers superior resistance to heat, oil, and the demanding conditions of the modern engine bay, providing the ideal balance of vibration damping and long-term durability that conventional rubber compounds cannot match. Substantial 5/8" through bolts capture the assembly. Replacement isolator sets are available below should replacement ever be needed.

Compactness

Geometry of the mounts is compact to provide clearance for all stock components including the steering shaft and exhaust headers.

Engine Mount Finish

The frame side brackets are designed to be painted or coated after welding, while engine block plates are treated with a rust resistant coating and can be painted to match your build.
