Made from 356-T6 cast aluminum, these girdles incorporate a reinforced crossbar. The crossbar houses the load bolts that apply pressure to the bearing caps. This feature, along with the thick casting, prevents bearing cap deflection under severe loads. Which in turn greatly reduces or eliminates (in most cases) bearing cap fatigue and failure. They also add fluid capacity, which helps to lower the fluid temperature. Comes with drain and fill plugs for easy maintenance.
Includes gasket, bolts, and instructions
These new Stainless Steel Stock Replacement 231 Turbo V6 headers will retain the same high tech features and manufacturing methods used in our highly successful performance headers, the best fitting and most powerful Turbo V6 headers ever produced and sold.
All fabrication and materials will be 100% USA, nothing imported. The turbo flange will also be the same precision cut 3/8" thick piece currently on TA performance V6 headers with elongated hole for precise turbo/downpipe alignment. These headers should fit all downpipes that fit with stock headers.
The stock drivers side header is notorious for cracking at the collector, requiring it to be welded or replaced. Since our driver's side header will be a direct stock replacement, it is available to purchase just a replacement header for the driver's side. In addition, being that a stock type crossover pipe will be utilized, they are available as a single purchase part also.
These headers feature a 1.5” primary header tube diameter and a 2.25” crossover tube diameter.
Make this the last set of headers you will ever have to buy for your `86 or `87 Grand National, GNX, T-Type and Turbo Regal. This all new design incorporates our new flanges that allow the use of 8 or 14 bolt heads, clearance for starters,as well as 3 or 3.5 inch downpipes. Our exclusive double wall slip fit crossover and thick 1/2” flanges provide for a leak free installation. Header kits come with all gaskets and mounting hardware.
Optional 4 bolt headers are also available from the dropdown menu belowNote: Headers do NOT fit stock downpipes.
Turbo, Internal & External Balancer. Can be used as interior or exterior with removable weight.
Note: All Production Buick Engines Were Externally Balanced
Stock & Stock Replacement Buick Balancers are not pressed on, they should slide on by hand. Forcing the balancer on could cause the balancer to crack at the keyway.
