COMP Cams Cam Phaser Limiter Kits
Comp Cams cam phaser limiter kits are specially designed, computer-controlled cam gears that automatically optimize camshaft timing based on the current engine rpm Engine oil is pressure-fed to the phasers through passageways in the cylinder heads and cams. The engine computers control solenoids that adjust this oil flow into and out of the phasers' control chambers, creating the ability to retard the cams. While this technology provides fuel efficiency and the ability to always be in the best position for maximum power, regardless of engine rpm, it does present some limitations when it comes to performance cams. With such a wide range of valve timing movement, there is very little piston to valve clearance, which limits you to small cam profiles with little overlap. COMP Cams cam phaser limiter kits restrict the range of cam timing movement (14 degrees for Chrysler, 20 degrees for Ford, and 22 degrees for GM), thus providing the necessary valve clearance for serious performance cams with tighter lobe separations--all while utilizing the benefits of VVT technology. Gain some serious upper rpm power without sacrificing bottom end or mid-range performance with Comp Cams cam phaser limiter kits.

Summit Racing™ Transmission Alignment Guide Pins
When mating a transmission to an engine, proper alignment of the 2 can get difficult. It's also critical to make sure the bellhousing and block dowels index correctly to get the bolts started. Summit Racing™ Transmission Alignment Guide pins simulate the bolts and assist with alignment by threading into the engine block to help guide the two together. The pins are tapered and the heads are slotted, so you mate the two together, start a couple of bellhousing bolts and then you can take a small screwdriver and remove them and replace them with the proper bolts. Make your next transmission install a breeze and align your transmission/bellhousing with our dowel pins as guides. Select the diameter needed for your application.
