If Your LS Swap Plans Include Three Pedals, We Have the Perfect LS Bellhousing Solution

When you get right down to the production numbers, as popular as the LS engine has been for GM, it has relatively low production numbers when backed by a manual transmission. Sure, there are diehard enthusiasts out there that order their F-body with a manual, but when you look at pure numbers most LS engine applications (Impala, GM truck, etc.) are either automatic only or have very low manual transmission production numbers.

So, when it comes to the budget friendly LS swap everyone loves for their classic GM muscle car, truck, or hot rod, it is tough to find a complete swap source with a manual transmission behind it. Therefore, it is often the case that your LS donor engine is either backed by an automatic, or the factory T-56 six-speed is long gone for someone else’s swap. While many will make plans to upgrade to a modern 5-speed transmission that can handle the increased performance potential of your LS swap, if you’re planning a turbo or supercharger upgrade you’ll need a transmission with greater torque ability. To do so means having the proper LS bellhousing to install the strongest manual transmissions out there; the Tremec T-56, TR-6060, or T-56 Magnum 6-speeds. Speedway Motors has the solution with our steel LS swap bellhousing.

Precision CNC machined and Fixture Welded for A Perfect Fit

We know the offerings for a 6-speed LS swap bellhousing are limited and we wanted to change that. Our steel LS swap T56 bellhousing provides the perfect answer to mounting the factory 6-speed from many of GM’s performance cars up to your new LS engine. Our steel LS bellhousing also provides you with the upgrade path to aftermarket 6-speeds from Tremec with even more torque capacity, such as the TR-6060 used in more recent performance oriented GM models, or Tremec’s T-56 Magnum (essentially a marriage of the stock T-56 with TR-6060 internals). Making this the perfect LS T56 bellhousing when it comes time to upgrade your transmission from the stock donor T-56 to the stouter aftermarket version.

Designed and manufactured in house here at Speedway Motors, you know you’re buying a quality product. We start with high strength steel and CNC laser cut the block mounting flange surface from .318-inch (5/16-inch) material. The transmission flange is cut and machined in the same manner from thicker .400-inch (13/32-inch) material. Both flanges are then held in a precise fixture with our 7-gauge steel formed 6-inch deep bellhousing and completely welded for a strong and tough T56 bellhousing assembly. The completed assembly is then given a black zinc coating for great, long lasting looks. Though not SFI rated, we do include a .115-inch (5/32-inch) thick cover plate and all new installation hardware.

Setup For Hydraulic Clutch Release Saves Installation Headaches and Provides More Room

Many classic vehicles use mechanical clutch linkage systems, which often do not mesh well with modern LS engine swaps and exhaust systems. Ditching the clutch fork and linkage is truly one of the best things you can do in a LS swap project, which is why our LS T56 bellhousing is only provisioned for hydraulic release bearing setups. Abandoning the clutch fork, linkage, and all that pivot hardware mess for a hydraulic release bearing and a vehicle specific or universal hydraulic clutch master cylinder system produces less pedal effort and really cleans up the engine bay. Our bellhousing features a 1.5-inch hole at the top 12 o’clock position for hydraulic line routing to keep line length as short as possible and away from hot exhaust system parts.

Installing the steel LS T56 bellhousing is no different than any other LS or SBC bellhousing. LS bellhousing bolts to secure the bellhousing to your LS block, along with 1/4-20 hardware to attach the cover plate to the bellhousing itself. You simply need to provide the 3/8-16 transmission mounting bolts for your 6-speed transmission, but if your old fasteners have seen better days or you simply don’t have any at all. Like any bellhousing installation we recommend checking and confirming alignment with a dial indicator and if required, installing offset dowel pins to correct any misalignment to prevent clutch engagement issues or noise. LS bellhousing dowel pins are the same dimensions as SBC dowel pins too in case you have some rolling around in your toolbox.

Our LS swap steel bellhousing is the perfect solution to mate your LS engine to your 6-speed transmission so you can get your project vehicle back on the road and under LS power sooner rather than later.

First off, I want to start by saying this is an amazingly well built unit. The welds are nice and the forming is top notch. Upon installation, I found that the threaded bolt holes in the Bellhousing are actually 3/8x16, instead of the 10x1.5x40 as stated on the website. Other than that it aligned nicely and looks like it'll offer some nice protection. Hope this helps someone in the future!
