The unique design of these distributors fit tight intake systems while still transferring the high voltage of the MSD racing ignition to the spark plugs. The high voltage carrying capabilities are the result of several features which have been designed into these low-profile distributors. This includes a large diameter cap with wide spaced terminals and an injection molded Rynite rotor with thick vanes to stir up the air inside the cap. The high dielectric Rynite base also prevents arcing to the billet housing. Since these distributors are used primarily in racing applications, an oversized steel shaft is responsible for delivering the sparks. This shaft is QPQ coated for friction reduction and receives guidance from a sealed ball-bearing assembly and an extra long, precision sintered bushing for smooth operation. Note: must be used with an MSD crank trigger and ignition control.

Product Features:

Designed to fit low in the block to clear firewall/intake combos
Supplied w/Bronze Gear
Supplied w/Large Diameter HEI Style Distributor Cap And Rotor
Must Be Used w/An MSD Crank Trigger And MSD Ignition Control

Our unique Multi-Layered steel head gasket embossment formation process optimizes the embossment radius, reduces stress points, enhances gasket conformability, and provides uniform clamp load distribution. This all results in superior surface contact between block and cylinder head. All head gasket layers/spacers go through an additional process to significantly reduce forming induced stress. Advantages are reduced brittleness in material, increased flexibility and deformation retention. This stabilizes the gasket, resulting in reduced cylinder bore distortion and improved combustion seal fro the extreme cylinder pressures found in high compression, supercharged and turbocharged applications. A proprietary polymer coating ensures the micro-seal of engine coolant and oil fluids.brbrA typical MLS head gasket requires a smoother (30Ra) surface finish than composite head gaskets. Mr. Gasket’s proprietary polymer coating will seal a surface finish twice as rough (60Ra) as a typical MLS head gasket. For high performance street, drag race and oval track use.

Product Features:

Gasket bore – 4.060″ Thickness – .040″
Manufactured from 3-layer premium grade stainless steel and state of the art laser cutting
Optimized sealing embossments seals extreme cylinder pressure
Provides excellent stability and reduces cylinder bore distortion.
Proprietary polymer coating ensures the micro seal of engine coolant and oil fluids.
Ideal for supercharged, turbocharged, nitrous oxide and extreme compression ratio engines

The MSD 8.5mm super conductor wire is the performance wire. 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 12 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) or 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. Available in universal kits and bulk lengths.

Product Features:

Less than 50 ohms per foot for superior spark
Ferro-magnetic impregnated core creates an effective EMI choke
40 ft. Of Conductor Wound Into A Single Foot Of Wire
For high EMI suppression
Conductor core features Dupont Kevlar material
Proprietary compound sleeves for resistance to high heat/abrasion

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.
