This version of our TJ / LJ mount is for Chevy Small Block V8 engines, entirely replacing the existing Jeep I4 or I6 frame mount.

Features
Ease of Installation
These mounts are available in either weld-in style or bolt-in style, and 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. When the option is available, we recommend the weld-in version for strength, simplicity and just a cleaner installation. If a welder is not available the bolt-in is an excellent option saving that step.
Vibration Isolation
Each mount kit comes with our high-grade urethane isolators that are specified for that ideal balance of isolation and firmness with the power of modern engines. Substantial 5/8" through bolts capture the assembly. Replacement bushing sets are available below should replacement ever be needed.
Compactness
Geometry of the mounts is compact to provide clearance for all stock components including steering shaft with its pillow block and the recommended exhaust headers below.
Engine Mount Finish
As the mounts are welded to the frame, any finish on the frame side brackets as well as the frame would be burned. you may enamel, powder coat or otherwise finish the bracketry and adjacent frame area to your own style. Engine plates are coated in a rust resistant finish but may also be painted.

Installation Requirements
Engine Placement
We have predetermined engine placement for the installer. There is a small window in which the GM Gen. I & II engines can properly fit into the TJ Jeep, and we've done this design legwork already.
Steering Bracket
These mounts feature an integrated platform for the reinstallation of your steering shaft carrier bearing bracket, as you may be removing the factory version. If installed correctly, the safety of your steering system will meet or exceed the factory specifications. Whether and how this is done varies with the original engine in your Jeep and the type of mount selected. Some (but not all) models use an additional spacer bracket that is supplied.
