SDP Deluxe Mega Brace Lifter Bore Reinforcement System SDP-LBB1-MBDUG

Improved Deluxe Mega Brace kit (for those who want to brace all the lifter bores) Now the new Deluxe Mega Brace can be installed in an assembled shortblock, no grinding required to clear any bolts.
Includes the improved Mega Brace complete kit (reinforces the #2 and #6 cylinder lifter bores), but also adds braces for all cylinders as well.

This upgrade is not necessary unless the engine is used in extreme applications.
Pricing: $369.90



This Mega Brace kit is only needed in extreme applications. The regular Mega Brace kit braces the more common areas that could present a problem. This deluxe kit braces the additional lifter bores that are less critical.

This is the strongest Pontiac lifter bore reinforcement system available.
This kit features simplicity of installation, no lifter bore distortion or cracking,
light weight, and no special tools or welding equipment required.

Pontiac "Mega Brace" Lifter Bore Brace System *can now be installed w/o grinding block* includes 3/8-24x1 1/4" grd.8 bolts and lock washers (3/8), Epoxy and Instructions

The Patented SD Performance Mega Brace lifter bore reinforcement system is by far the strongest lifter bore brace on the market today. With over 1000 braces sold with no reported problems, it's no wonder more and more engine builders like Butler Performance are selling and using the Mega Brace in engines they build. It's simple to install and will allow you the option of running today's big hp aggressive roller cams without the fear of lifter bore failure.
