Product Description
Texas Speed 408" Forged Balanced LS 58x Rotating Assembly 15cc Dish
Fits 1999-2018 6.0L Iron blocks that have been machined to 4.030" Bore L96 LY6 LQ4 LQ9
58x Crank Reluctor - Generally used with 2007-Later GM PCM's or Aftermarket EFI Systems
This TSP 408 cubic inch stroker kit features 15cc dished pistons for use in 6.0L iron block applications. Depending on cylinder head, head gasket and fuel selection, this combination can work well for a variety of naturally aspirated, supercharged, turbocharged and nitrous combinations (see compression ratio chart below). These kits will conservatively handle 1,000hp in boosted applications. This fully forged rotating assembly includes a TSP Forged Crank, TSP 4340 H-Beam Connecting Rods with ARP Bolts, and Wiseco Forged Pistons. Typically, it takes several weeks and multiple trips to a machine shop to have a rotating assembly balanced. We have sped up the process by having this rotating assembly precisely balanced ahead of time so it is ready to be installed.
The same high quality parts Texas Speed uses in their popular Brawler engines, now available in a balanced & ready to run rotating kit! All rotating assemblies come with Clevite main & rod bearings, and piston rings. The crankshaft will come with a 58x reluctor wheel for high rpm crank signal accuracy. The crankshaft will also be digitally spin balanced to the weight of your new rotating assembly, on TSP's CWT balancer, ensuring smooth, trouble free operation.

- Texas Speed 4.000" Forged 4340 Crankshaft with 58x Reluctor, 6-bolt Flange
