Chevrolet Performance Bowtie Big Block Chevy Cast Iron Engine Blocks

Chevrolet Performance Bowtie big block Chevy cast iron engine blocks are CNC-machined. The race-prepared blocks feature blind head and accessory mounting bolt holes, a deck configuration that enables the use of any big block Chevy cylinder head—and cylinder bores that may be safely bored to a 4.600 in. maximum diameter, while maintaining a .250 in. minimum cylinder wall thickness. These engine blocks differ from the production-machined Bowtie versions in certain areas; they start from raw castings and are not "conversions." They also use a rear seal adapter to convert the Gen V/VI one-piece rear main seal to a Mark IV type 2-piece seal that facilitates the use of a widely available Mark IV style crankshaft. The intermediate caps also feature 16 splayed outer bolts, which anchor the caps into the strongest section of the blocks and prevent bearing cap movement under high loads. The main oil gallery on these blocks is relocated and enlarged to a 9/16 in. diameter to allow increased oil flow through the block. These Bowtie blocks have inner head bolt bosses, which allow for better retention of the cylinder heads in high-horsepower applications when the cylinder heads "lift" from the blocks due to high cylinder pressures. Order the style and deck height preferred for your application.

Spidertrax Off-Road Ultimate Steering Knuckles

Spidertrax Off-Road Ultimate steering knuckles set the standard for rock crawling and rock racing performance. They now include 7/8 in. spherical bearings and 4340 Spider shoulder bolts across the line. In addition, they feature internal gussets on both upper outer knuckle and lower inner knuckle, adding crucial strength from extreme steering forces and those high impacts from jumps. Ultimate knuckles are designed for Ultimate unit bearings, Ultimate U-joints, and 4140 bolt-on high steer arms (sold separately). They install on any Spider 9 housing with 3 1/2 in. O.D. tubes. * CNC-machined: Tight tolerances are necessary for proper fitment. Post welding, all inner knuckles are CNC-machined. This provides not only a perfect 7/8 in. spherical bearing fit but a precise tolerance between upper and lower spherical bearings. No guesswork, no compromise. * 7/8 in. bolts and bearings: The spherical bearing assembly consists of a 4340 Spider shoulder bolt, shim washer, spherical bearing, shoulder washer, and Type C nut. Combined, each knuckle can withstand over 21,500 lbs. of axial loading and over 130,000 lbs. of radial loading. No grease, no weak links, no hassle. * 50 degrees of steering: An OEM-style 60 knuckle can turn only 38 degrees. Ultimate knuckles can turn all the way to 50 degrees, tighter than any steering knuckle on the market. Plus, the use of a 6-bolt interlocking chromoly steering arm makes them one of the strongest, as well (steering arms sold separately). * Internal gussets: Ultimate knuckles take performance to an all-new level with the addition of internal gussets. Upper outer knuckle gussets add critical strength for steering, while lower inner knuckle gussets add extra strength for those high sailing jumps. They're simply Spidertrax's strongest Ultimate knuckle yet.
