Speed up your installations and add some serious impact power to your tool line up with Harbor Freight’s new ½-inch professional class pneumatic air impact wrench. Capable of delivering 700 lb-ft of torque, with a range from 50 to 500, the Earthquake can run at 8,000rpm free speed and works with any compressor capable of handling 90-psi of working pressure. At 6-lbs, the Earthquake is well built and it offers less vibration at a lighter weight than its competitors, according to the manufacturer. Three forward speeds will allow you to use precision when needed and massive torque when necessary, with enough reverse power to break free the most stubborn hardware. At under a hundred bucks with a 90-day warranty, this is a hard impact wrench to beat.

Looking to add upwards of 100-rear-wheel horsepower and similar torque to your 4.8 or 5.3-liter truck project? Edelbrock has got you covered with the company’s newly released line of E-Force superchargers for ’07-’12 GM trucks equipped with either LS engine option. Using the same Eaton TVS Gen VI rotors found in the ZR1, the Edelbrock E-Force makes reliable power for years and can even be purchased with a 5-year/100,000-mile warranty that covers up to $20,000 in repair, should you ever need it. Testing on a stock 4.8 took power from 228 to 334, while the 5.3 saw gains from 270 up to 364hp. Torque output is even more impressive, with the 4.8-liter engine jumping from a meek 259 lb-ft up to a stout 380 lb-ft. Of course, you get everything you need for the installation in one order and, since the kit is designed to be 50-state legal, you won’t have to worry about the cops.

Paying attention to your engine’s vital signs is always a good idea, but you don’t have to run a set of gauges that make every slack-jawed import driver want to race you down the freeway. Thanks to Autometer, owners of ’99-06 GM diesel truck rigs can monitor boost pressure, fuel rail pressure, EGTs, and transmission temperatures on the fly while blending these gauges in perfectly with the factory cluster. Of course, you still get all of the accuracy and reliability that Autometer is known for, with each gauge shipping to you with the proper sensors and wiring to make everything work correctly. The design is practically spot-on for all ’99-06 haulers and the custom tuned high-definition LED illumination matches the interior lighting perfectly. Combined with the orange pointers, you get precision measurement and a factory stealth look all in one.

When Pfadt Race Engineering set out to build the ultimate fifth-generation Camaro coilover, they didn’t simply head overseas and order up a set of generic units. These ’10 and up Camaro coilovers were designed, engineered, and built entirely in house at the Pfadt control center in Salt Lake City and perfectly blend race quality handling with street friendly manners. For the money, you get a set of fully ride height adjustable coilovers, which feature Camaro specific valving and fully adjustable 24-click front and 48-click rear dampening control. With a Ball On Axis (BOA) upper mount for wide articulation with low friction combined with an inverted shock design, and Pfadt Concentric Integrated Remote Canister (CIRC) technology, you’re getting Corvette technology in a Camaro body. Oh, and these bad boys drop 34-lbs over the factory units, while significantly improving strength. They’ll bolt to any fifth-gen Camaro, including the ZL1, and are ready to ship today.

There comes a point in every project’s life when it needs to be strapped down to a trailer. Whether it’s to get a race car to the track, or pick up a broken street car from the side of the road, it’s going to happen eventually. And, when it does, you should be prepared to properly secure it to your trailer to avoid any accidents while towing. For that, check out Mac’s Ultra Pack, which ships complete with everything you need for a safe and secure strapping procedure. Made right here in the USA, you get four ratchet straps (6 or 8-feet), four loop-around axle straps, a Mac duffle bag to hold them all, and four straps to secure the excess webbing once your ride is hunkered down. With twice the number of stitches compared to most competitors, the Mac’s straps are rated to handle 10,000-lbs, so even the fifth-gen guys can safely tow to the racetrack and back (we kid, we kid).
