MSD Ignition – Super Conductor Spark Plug Wire Set – 1999-2013 GM Truck & SUV, Black (Part No.32823)

Super Conductor Spark Plug Wire Set - 1999-2013 GM Truck & SUV, Black

from

$119.99
Engineered from the inside out, the 8.5 offers everything you have ever wanted in a wire; incredibly low resistance without electronic interference. In a single 11 inch length of Super Conductor Wire there is only 40 – 50 ohms of resistance. That is the lowest resistance of any helically wound wire. To accomplish this, we use a copper alloy conductor due to it’s great voltage carrying capabilities. The low resistance results in less loss in spark energy so more reaches the spark plug. The conductor is wound extremely tight around a special center core. So tight in fact, that there is over 40 feet of conductor wrapped into a single foot of plug wire. This winding procedure, combined with a ferro-magnetic impregnated center core, produces an extremely effective Electro Magnetic Interference (EMI) “choke”. This choke, or suppression capability, keeps the EMI inside the wire where it cannot interfere with other electronics on your vehicle. The outer sleeve that surrounds the conductor assembly is just as impressive. A proprietary blend of silicone and synthetic material produce a sleeve that is highly resistant to high heat as well as abrasion and tears. The MSD’s 8.5mm spark plug terminals feature Dual Crimp terminals. As the name implies, the terminals feature two crimps; one for the sleeve of the wire and another separate crimp to grasp the conductor. The MSD’s 8.5mm spark plug terminals feature Dual Crimp terminals. As the name implies, the terminals feature two crimps; one for the sleeve of the wire and another separate crimp to grasp the conductor.

MSD Ignition – Super Conductor Spark Plug Wire Set – 1999-2013 GM Truck & SUV, Black (Part No.32823)

Super Conductor Spark Plug Wire Set - 1999-2013 GM Truck & SUV, Black

from

$119.99
Engineered from the inside out, the 8.5 offers everything you have ever wanted in a wire; incredibly low resistance without electronic interference. In a single 11 inch length of Super Conductor Wire there is only 40 – 50 ohms of resistance. That is the lowest resistance of any helically wound wire. To accomplish this, we use a copper alloy conductor due to it’s great voltage carrying capabilities. The low resistance results in less loss in spark energy so more reaches the spark plug. The conductor is wound extremely tight around a special center core. So tight in fact, that there is over 40 feet of conductor wrapped into a single foot of plug wire. This winding procedure, combined with a ferro-magnetic impregnated center core, produces an extremely effective Electro Magnetic Interference (EMI) “choke”. This choke, or suppression capability, keeps the EMI inside the wire where it cannot interfere with other electronics on your vehicle. The outer sleeve that surrounds the conductor assembly is just as impressive. A proprietary blend of silicone and synthetic material produce a sleeve that is highly resistant to high heat as well as abrasion and tears. The MSD’s 8.5mm spark plug terminals feature Dual Crimp terminals. As the name implies, the terminals feature two crimps; one for the sleeve of the wire and another separate crimp to grasp the conductor. The MSD’s 8.5mm spark plug terminals feature Dual Crimp terminals. As the name implies, the terminals feature two crimps; one for the sleeve of the wire and another separate crimp to grasp the conductor.

HoleShot 2400 for GM 1993 to 1996 TH700R4 (30 spline) and 1984 to 1993 4L60E (30 spline) Application: HoleShot 2400 for GM 1993 to 1996 TH700R4 (30 spline) and 1984 to 1993 4L60E (30 spline) A higher than stock stall speed as delivered by the Holeshot converter will provide several advantages and benefits in vehicles with modified engines. Many modifications, particularly big cams, tend to reduce low end power and torque. The high stall converter allows the engine to launch the car at higher rpm where more torque is available. The Holeshot is generally a very good choice for the typical street machine that is looking for better launch capability and more strength. Street rods with modified engines will also benefit from a Holeshot converter. If your vehicle is equipped with a plate type nitrous system, you will need a Nitrous Holeshot!! Stall speed listings are based on engines producing 230lb. ft. of torque at 2,500 rpm. More torque at 2,500 rpm will give you more stall speed, less torque at 2,500 rpm will give you less stall speed than the stall speed ratings indicated. Furnace brazed impeller.

Energy Suspension – Hyper-Flex Polyurethane Body Cab Mount Set (Part No.3.4150G)

Hyper-Flex Polyurethane Body Cab Mount Set

from

$289.99
Will replace distorted and worn-out original rubber mounts to maintain car body and truck cab to bed alignment. Original rubber mounts are so soft they often crack, distort, and crush so badly they often fall off. And aluminum body mounts are too harsh for street use that they tend to break and cause other components to break. Energy’s specially formulated Hyper-Flex polyurethane cab and body mounts combine the best qualities of both: they’re soft enough for a smooth ride, yet rugged enough for the most demanding road or track. Most sets have a strong zinc plated steel ring molded into them – for added durability and when the application requires it.

Product Features:
  • Assures Longer Lasting Cab To Bed Alignment
  • Replace To Restore Ride Height
  • Gain Durability
  • Stronger Than Original Rubber Mounts
