As everyone knows the propshaft coupler is a weak spot in your C5/C6 driveline. We have seen these fail and cause major damage to the torque tube assembly. Our billet couplers will help prevent that failure from happening.

These are designed to work with the 12MM propshaft that is used in the 2001 and later Corvettes. We recommend using new GM hardware when installing the couplers. These will not work in 2000 and earlier C5's with the 10MM propshaft hardware.

Specs

Machined billet aluminum component with reliefs for reduced weight.

Hard anodized black finish for durability. 

Kit includes two couplers. New GM 12MM hardware available as an option.

GSpeed has the perfect driveline solution for your C5 Corvette.   OE rubber driveline mounts are designed to provide a quite and comfortable ride for a production car.  Racing and high hp use requires a more positively located driveline mounting solution free from breakage and heat failure.  Our billet mounts are designed to provide strength, yet be lightweight so they do not penalize you for the added strength.    

The package includes our billet solid engine mounts and our new billet transmission mount. Eliminate driveline movement under load with this package.

All mounts include high grade mounting hardware.   MilSpec anodized finish.  

Fits all 1997-2004 Corvettes.  

I’m sure we have all experienced breaking a blower belt in the past. The last customer that broke one cost $1100 to repair the hood

After a little design work, this is what we came up with for owners of Corvette’s using Procharger F1 series of head units.  Easy to use and easy to install.   

(Note: Guard will only fit with Procharger & Dallas Performance supercharger mounting bracket)

Clutch size, weight, durability, and holding capacity have always been a balancing act.  With today’s engines making more and more HP and TQ every year the need for a smaller diameter, lighter weight clutch to hold that power has been harder to do. 

Now GSpeed has a 4 plate, 7.25” diameter clutch that weighs in at just 21.4lbs (including flywheel) and can handle up to 1300 ft-lbs of torque is just what you need!  

This system is a bolt in replacement for your OE flywheel, clutch disks, pressure plate, and troublesome OE slave cylinder.  

Reduction of up to 46.25lbs over the OE clutch!  

We have trusted Tilton for our race cars, and customer cars for decades, now you can put your faith in a clutch that works!   

Update: Flywheel design revision has eliminated the holes in the flywheel as shown in the images. This is done to increase strength in the flywheel with minimal weight gain.

GSpeed Spec'd Dailey 4.5 Stage LS Dry Sump Kit

Includes the following Components 

Gspeed Spec'd Oil Pump, and machined pan designed for our in house race cars. This kit also includes pulleys, belts, gasket, fittings, installation hardware and ATI Damper for your application.

Dailey Engineering Dry Sump Oil Pans are made from billet 6061 T6 aluminum. With the oil pump bolted directly to the oil pan, it eliminates A/N lines between the oil pump and the pan.  All scavenge lines are internally machined into the oil pan eliminating the costly weight, expense, and bulkiness of external scavenge A/N lines.

ST-246 Clutch Kits…. Racing Technology applied to the Street.

Tilton has applied their nearly 50 years of experience in racing clutches to develop the ST-246 line of 246mm (9.7”) twin disc clutch kits for the high-performance street market. Unlike many of the “performance clutches” on the market, ST-246 clutches were engineered from the ground up as a true performance twin disc clutch and not an OEM-type stamped steel pressure plate with a floater plate added. ST-246 clutches are designed to provide high torque capacity, low wear rate, smooth shifting and good drivability. All ST-246 twin disc clutch kits include
a billet chromoly steel flywheel and are available with either sprung-hub organic discs (850 lb-ft capacity) or solid-hub cerametallic discs (1250 lb-ft capacity).

Tilton has now applied their nearly 50 years of experience in racing clutches to develop the ST-246 line of twin disc clutch kits for the high-performance street market. Unlike many of the “performance clutches” on the market, ST-246 clutches were designed from the ground up as a true performance twin disc clutch and not an OEM-type stamped steel pressure plate with a floater added. Featuring an aluminum clutch cover that shares technology from Tilton’s championship winning line of OT- Series racing clutches, ST-246 clutches feature heavy duty straps that attach the pressure plate and floater plate to minimize noise. ST-246 clutches are available with either sprung-hub organic discs for street applications or solid-hub cerametallic discs for street/strip applications.

All kits include a billet chromoly steel flywheel that features a precision register for the clutch to provide optimal balance of the clutch/ flywheel assembly.

ST-246 clutch kits for Corvette C5 are designed to work with the OEM slave cylinder. Most importantly, Tilton ST-246 clutch kits offer all this technology at a price point that is very competitive to the other clutches on the market.

Precision machined aluminum clutch cover high-strength, stiffness and better balance than OE-type stamped steel covers.

High-mass main pressure plate and floater plate machined from the same proprietary materials as used by Tilton’s racing clutches, provides high heat capacity and resists warpage. Heavy duty straps attach plates to cover to minimize noise and provide clean clutch release.

Organic disc option, with sprung center hub to dampen engine vibrations and reduce gearbox noise, provides smooth engagement for street use and holds 850 lb-ft of torque.

Cerametallic disc option, with solid center hub for higher strength, provides positive/precise engagement characteristics for streets/strip and holds 1250 lb-ft of torque.

Chromoly steel flywheel provides high strength and long-term durability.  Features a precision register to locate the clutch and provide optimal balance, as opposed to loose fitting bolts & dowels used with stamped steel clutches.

The LS valve train has been a very stable platform for most and with the advent of higher lift cams and stiffer valve springs has came a need for a slight upgrade to the OE rocker system under severe use.  

Comp Cams has solved just that issue with their new BSR Max Lift shaft mounted rocker system.  Long gone are the needle bearings or having to fool with trunion upgrades.  Now a tri layer bearing is used just like on your main and rod bearings. No parts to loose if something goes wrong.  The entire set of rockers is now also ran off of one main, large shaft to increase rocker stability and stiffness.  This means more lift at the valve and a more stable valve train for those turning more RPM.  

Speaking of more lift, the BSR series allows you to safely run 0.675“ lift on LS1 and LS3 style heads and up to 0.700” lift on the LS7 style.  

We have ran these on a number of our engines without issue and highly suggest them on our more aggressive road race builds.   

COMP Cams® Billet Valve Covers for GM LS Engines clear all types of valve train components for GM LS engines, including shaft mount rocker systems, and provides for internal valve spring oiling.

They feature OE-style gaskets and hardware for superior sealing, a -16AN oil fill port for easy filling, a breather location for dry-sump oiling systems and internal baffling for an optional 3/8" breather/vent line. The valve covers also have provisions for valve spring oil squirters to help cool valve springs and increase their life in endurance racing applications. A bright black anodized finish and stainless steel ARP fasteners offer a clean appearance.

COMP Cams® Billet Valve Covers work on all GM LS center bolt cylinder heads, engines with tall or shaft mount rocker arms and endurance applications requiring extra spring oiling. Coil mounting provisions are available using COMP Cams® brackets, sold separately.

LSX™│For LS7 Port Heads 

FAST™ engineers teamed up with airflow specialists at RHS™ to develop a polymer intake manifold for rectangular port GM LS7 engines. Testing on a 500ci LSX engine with LS7 heads and a Big Mouth 102mm Throttle Body™ this manifold produced gains of 26 RWHP over the stock intake. The LSXR™ 102mm Intake Manifold features a three-piece modular design that allows easy disassembly and porting. Extensive testing led to a runner design that is longer and less restrictive and gives the user the ability to remove individual runners from the manifold for modification.

Constructed from the same advanced polymer material as the LSX™ 92mm Intake Manifold, the LSXR™ offers a host of benefits over aluminum aftermarket intakes, including lighter weight, increased strength and improved heat dissipating characteristics. While the LSXR™ features a 102mm air inlet that is perfectly suited to the FAST™ Big Mouth 102mm Throttle Body™, it can also be used with stock or aftermarket 90mm or 92mm throttle bodies. Other features include integrated nitrous bungs and perfect bolt-on fitment that allows the use of factory accessories without modification or clearance concerns.

LSX™│For LS3 Port Heads 

FAST™ engineers teamed up with airflow specialists at RHS™ to develop a polymer intake manifold for rectangular port GM L92/LS3 engines. Testing on a stock LS3 engine with a Big Mouth 102mm Throttle Body™ produced gains of 14+ horsepower and 11+ ft/lbs of torque at the flywheel over the stock intake. The LSXR™ 102mm Intake Manifold features a three-piece modular design that allows easy disassembly and porting. Extensive testing led to a runner design that is longer and less restrictive and gives the user the ability to remove individual runners from the manifold for modification.

Other features include integrated nitrous bungs and perfect bolt-on fitment that allows the use of factory accessories without modification or clearance concerns.

Due to a patented removable runner design and the introduction of two additional runner sets, LSXR™ 102mm Intake Manifolds from FAST® now have the capability to shift torque and horsepower gains to a higher RPM than the original version, making them the most flexible options on the market. In addition to the original FAST® LSXR™ 102mm Intake Manifold & Runner Set, High HP and Race versions are now available. The new interchangeable, complementing runners are designed specifically for LS3, L99, L76 and L92* engines that are built for high performance applications. The High HP Runner Set is based on Daytona Prototype intakes and utilizes newly designed runners, which are shorter and straighter than conventional versions. The High HP version has been proven to make 8-10 horsepower over the original LSXR™ manifold with a 500-1000 RPM shift up in peak horsepower on LS3 performance engines. However, it maintains all of the same features and benefits of the standard LSXR version. The Race Runner Set features a short and straight runner design that rivals aluminum four-barrel intakes on horsepower potential. This manifold setup utilizes a race version of standard runners designed for all-out high RPM performance. It is ideal for race vehicles with serious performance modifications and race converters. The Race version provides a 15-30 horsepower gain with a 1000-2000 RPM shift up in peak horsepower, but will lose some low-end torque. The runners are interchangeable and available in kits so manifolds may be configured as the original LSXR™ with standard street runners, or the new HP or Race models. A master kit is also available featuring an intake manifold assembly and all three runner options.
