Handle Big Boost, Install a Better Bellhousing, and Light Up Your Dash with These Summit Racing Brand Products

If you have a GM LS engine making serious boost, need to replace an old GM manual transmission bellhousing, or want some extra-bright indicator lights on your dash, these Summit Racing brand products have you covered.

Summit Racing™ LS CNC Billet Intake Manifolds
Looking for an intake for your LS engine that can handle big horsepower and big boost? Summit Racing™ LS CNC Billet Intake Manifolds are rated to 2,000 horsepower and over 300 PSI of boost. If your LS has a turbo setup making that kind of boost, we’d like to see it.

Designed for cathedral-port heads, the manifolds have CNC-machined billet aluminum plenums and bolt-on runners that will not distort or warp under boost. The manifolds accept 102mm throttle bodies and help build power from 1,800 to 7,000 RPM. Fuel rails, an -8AN fuel line kit, gaskets, and hardware are included. Your choice of black or satin finishes.

Summit Racing™ Manual Transmission Bellhousing Kit
The factory 621-style cast aluminum bellhousings used on four-speed equipped V8 Chevy and GMC cars and trucks were not a super-precision part. Clutch misalignment and clutch linkage flex were often issues that led to sloppy shifting and premature transmission wear.

You won’t have those problems with a Summit Racing™ Manual Transmission Bellhousing Kit. It includes cast aluminum housing with extra-thick walls and CNC-machined facings, bores, and mounting holes. Runout is kept to a minimum for accurate clutch alignment and shift quality. The kit comes with a new clutch fork, throwout bearing, clutch fork pivot ball and boot, and an inspection cover with mounting bolts.

The Summit Racing Manual Transmission Bellhousing Kit is designed for use with passenger car transmissions that have an 11- inch clutch and 14-inch, 168-tooth flywheel. It accepts OEM-style starters compatible with manual transmissions. The bellhousing can be used with Borg Warner T-10, Muncie, and Saginaw four-speeds.

Summit Racing™ LED Indicator Warning Lights
Make sure you know when something electrical is activated with these extra-bright Summit Racing™ LED Indicator Warning Lights. Ideal for switch panels, the lights will alert you when a circuit has been activated. They’re also handy for use as turn signal or headlight indicators. We’re sure you’ll find other uses for them, too. The Summit Racing LED Indicator Warning Lights are available with amber, red, blue, or green lights with a choice of chrome or black housings. The black indicator light is also available with a white light.
