GMC / Chevrolet no longer offers the 3500HD pickup truck. There is still a dual rear wheeled 3500, but its maximum GVWR is only 11,400lbs. The Class 4 & 5 GVWR ranges (14,001 to 19,500lbs) that used to be covered by the 3500HD are now part of the GMC / Chevrolet TopKick / Kodiak (4500/5500 family) line of trucks. The TopKick / Kodiak line of trucks is much more similar in overall construction to its heavier GVWR cousins than it is to the old 3500HD pickup trucks. Therefore, the DMF RW-1019 railgear has been modified to better suit this line of trucks. The redesigned RW-1019 for TopKick /Kodiak trucks is very similar to the larger DMF RW-1212 and RW-1420 railgear. The only difference between this RW-1019 for the Chevy /GMC 4500 / 5500 series trucks and the RW-1212 and RW-1420 line is the size of the rail wheels, bearings, axle and the pivot arms.

1. From under the vehicle use a measuring tape to measure from the muffler box seam back along the axis of the muffler inlet pipe 59mm (2.32”) and mark the point on the exhaust pipe. ( see figure 1) Note: This cut position is the same on both LH & RH side Exhaust Pipes.
2. Confirm the mark is in the correct location and cut the pipe along the marked cut line.
3. Remove the muffler from its rubber hangers and discard the old muffler. ( see figure 2) De-burr the end of the exhaust pipe.
4. Slide the exhaust clamp onto the new exhaust pipe. Install the replacement muffler onto the rubber exhaust hangers and slide the muffler onto the exhaust pipe. ( see figure 3)
5. Position tip in rear valence and tighten the clamp bolt to 32-35 FT.-LBS. ( see figure 4)
6. Repeat instructions for the opposite side.

Disconnect battery & remove all existing accessory drive brackets and components from motor. Remove water pump, scrape away any existing gasket material with a gasket scraper and dress surface with a Scotch Brite? pad. Clean and prep threads on engine block at water pump (3/8-16) and driver side bosses (7/16-14) by crank (for power steering kits). Use a 3/8-16 & 7/16-14 thread chaser if necessary. Thread chasers are available at your local auto parts store or tool dealer and are different from a thread cutting tool. Apply RTV sealer to one end of the four 3/8-16 x 3” threaded studs and thread studs into the water pump mounting holes and tighten. The studs can easily be tightened by threading two 3/8-16 zinc coated nuts onto the stud and tighten them against each other to act as a drive nut.

INSTALLATION PROCEDURES:
The saddle mount kit is designed to be used with 1987-95 YJ Wranglers. This mount is designed around a stock oil pan. If you are using an aftermarket oil pan, the maximum depth in the front is 4-1/2″. GM part number 12557558 (1986 and newer) has a front depth of only 3-1/2″ and provides the most mount to pan clearance We have designed this mount to position your new engine in the best location possible. Driveshaft modifications may be necessary depending on your application. We have had requests to allow some lateral adjustment with this mount. To supply this adjustment we have provided two 5/8″ spacers. Using these spacers, you can space the stock rubber mount 5/8″ to the front or rear of the saddlemount location.

Before Starting Installation
1. Carefully read all warnings and instructions completely before beginning.
2. Verify all parts have been received in this kit by checking the parts list at the end of this document.
3. Only install this kit on the vehicle for which it is specified. If anytime during the installation you encounter something different from what is outlined in the instructions, call technical support at (928) 636-7080.
4. Park vehicle on a clean, dry, flat, level surface and block tires so vehicle cannot roll in either direction.

Engine Compartment
1. Measure and record distance between cab and bed.
2. Disconnect both battery cables. Disconnect negative cable first, then positive cable.

Step 1 – Vehicle Preparation
Remove the negative battery cable. With the vehicle on a solid level surface, chock the front wheels. Using a jack rated for the weight of your vehicle, raise the wheels off the ground. Lower the vehicle frame onto jack stands rated for the vehicle weight, making sure the suspension is fully extended. (Do not use wood or concrete blocks to support the vehicle.)

DESCRIPTION: The Edelbrock RPM Air-Gap #7116 intake manifold has been designed for 262-400 c.i.d. small-block Chevy engines equipped with Vortec style (L31) cylinder heads. The manifold accepts late model water neck, air conditioning, alternator and H.E.I. ignition systems. Use electric or manual type choke square bore carburetors only. This intake manifold is recommended for street high performance, marine and race vehicles (where dual plane manifolds are required).

The RPM manifold provides good low rpm response for street performance vehicles while providing increases in horsepower and torque up to 6500 RPM. When used with any mix of aftermarket equipment designed for this operating range, the performance increases will be even greater.

Motor vehicle theft is a serious problem in many parts of the world. In the United States, the annual loss from car theft is over $4 billion. The Automotive Information Council reports that over one million motor vehicles are stolen in the U.S. each year. That’s one motor vehicle theft every 31 seconds. For a variety of reasons, some motor vehicles have a greater probability of being stolen than others. As reported by CCC Information Services, Inc., the following are the 25 most stolen motor vehicles in the U.S. in 1996:
