Special applicationS – FullullSize SerieS (4x4)4) pecial applicationS – F Size K K SerieS (4x SP–1 SP— 1 PAGE PAGE SNOWPLOW PREP PACKAGE (VYU)The chart on the page SP-4 shows GMTG and General Motors approved models available with snowplow prep package-option VYU.GM recommends that when a snowplow is mounted on a vehicle, only one passenger should accompany the driver. More than one pas-senger may exceed Front Gross Axle Weight Ratings.Prior to installing a front mounted snowplow, the following process should be followed and necessary information obtained. • Establish vehicle curb weight • Establish chassis manufacturer’s front and rear axle weight ratings • Chevrolet and GMC truck dealers can provide availability, specifications, Gross Vehicle Weight Ratings (GVWR), and Front and Rear Gross Axle Weight Ratings (FGAWR/RGAWR). For vehicles already built, this information can be found on the certification label installed on driver’s door/door frame or provided on the cover of the Incomplete Vehicle Document.The following information should be obtained and provided by the manufacturers of snowplows and salt spreaders: • Specifications, weights and center of gravity data • Vehicle installation guidelines and instructions • Calculation of weight distribution for the front and rear axlesThe loaded vehicle with driver, passenger, aftermarket accessories, snowplows, spreader, and cargo must not exceed the Gross VehicleWeight Rating (GVWR), and Front and Rear Gross Axle Weight Ratings. In addition, the completed curb weight vehicle, with all installed aftermarket accessories, snowplow, and spreader, and with 400 lbs. for vehicles less than 10,000 lbs. and 500 lbs. for vehicles greaterthan 10,000 lbs. distributed in the driver-passenger area of the vehicle, must have a center of gravity location that is located within thetrapezoid formed by the coordinates A, B, C, D, H1 & H2, plus it must be to the rear of vertical line E and forward of vertical line F as defined in the ALLOWABLE CENTER OF GRAVITY CHARTS. If the center of gravity location does not fall within the specified trapezoid, ballast weight may be required to shift the center of gravity location until it falls within the specified trapezoid.The snowplow manufacturer and the installer of the aftermarket equipment should determine the amount of rear ballast required toensure that the vehicle, with the attached snowplow and aftermarket equipment, complies with the Allowable Center of Gravity Trapezoid and the resulting front and rear weight distribution ratio as defined in the Allowable Center of Gravity Charts published in this manual.

Special applicationS – FullullSize SerieS (4x4)4) pecial applicationS – F Size K K SerieS (4x SP–2 SP—2 PAGE PAGE(Snowplow Prep Package — continued from previous page)Ballast Compensating WeightThe use of rear ballast weight may be required to prevent exceeding the Gross Axle Weight Rating of the front axle. The use of rearballast weight may be required to ensure that the center of gravity location of the completed vehicle, with the attached snowplow andother installed equipment, complies with the Allowable Center of Gravity Trapezoid and the resulting front and rear weight distribu-tion ratio, even though the actual front weight may be less than the Gross Axle Weight Rating of the front axle. In either case, the rearballast weight should be securely attached in the cargo box or behind the rear axle of the vehicle in a manner which prevents it frommoving during driving and stopping. To help avoid personal injury, refer to Z-height setting procedure before adjusting torsion bars. If torsion bars are adjusted for aftermarket equipment, be sure to return them to specifica- tion when the equipment is removed. Otherwise, a front shock absorber may dislodge and damage a front brake line. This could result in an accident when minimum stopping distances are required.Special Applications – SPPP – 2011Special Applications – SPPP – 2007

Special applicationS – FullullSize SerieS (4x4)4) pecial applicationS – F Size K K SerieS (4x SP–5 SP— 9 PAGE PAGE CMVSS105 and FMVSS105 Allowable Center of Gravity CalculationC/G of vehicle in CMVSS or FMVSS unladen condition [Curb + 181.4 kg. (400 lb) or Curb + 226.8 kg. (500 lb) as defined by CMVSS105 and FMVSS 105] must be inside shaded area – that is, the C/G must be within the trapezoid formed by the coordinates A, B, C,D, H1, & H2, plus the C/G must be to the rear of vertical line E and forward of vertical line F.The center of gravity of the total vehicle falls within the areas referenced on the “ALLOWABLE CENTER OF GRAVITY CHART” that follows. Instructions for determining the allowable center of gravity variation are listed below:These charts detail the envelope of allowable center of gravity variation for completed vehicles. This is significant for the lightly loaded por-tion of FMVSS 105, which is defined as curb plus 181.4 kg (400 lb) distributed in the driver-passenger area of the vehicle for vehicles with GVWR of 4536 kg (10,000 lb) or less or as curb plus 226.8 kg (500 lb) distributed in the driver-passenger area of the vehicle for vehicles with GVWR greater than 4536 kg (10,000 lb).The lightly loaded center of gravity complete vehicles needs to be restricted so it will meet FMVSS 105 stopping distances. The laden centerof gravity does not need to be specified as it is controlled within the CMVSS 105 and FMVSS 105 test procedure by specific instructions as to how ballast is to be placed (while height is not controlled, it is assumed that for test purposes it would be reasonable).For Body Builder’s use, the center of gravity location can be approximated by the following formula: d = [Wrc + Wrb + [(Hp)(Wp)/WB]] WB Wt h = [h1Wc + h2Wb + (h3)(Wp)] Wt d = horizontal distance from front wheels to completed vehicle center of gravity cm (in) (continued on next page)Special Applications – SPPP – 2011Special Applications – SPPP – 2007

(400 lb)] must be inside shaded area – that is, the C/Gmust be within the trapezoid formed by the coordinates A, B, C, D, H1, & H2, plus the C/G must be to the rear of vertical line E andforward of vertical line F.The center of gravity of the total vehicle falls within the areas referenced on the “ALLOWABLE CENTER OF GRAVITY CHART” that fol-lows. Instructions for determining the allowable center of gravity variation are listed below:These charts detail the envelope of allowable center of gravity variation for completed vehicles. This is significant for the lightly loaded portion of CMVSS 135 and FMVSS 135, which is defined as curb plus 181.4 kg (400 lb) distributed in the driver-passenger area of the vehicle.The lightly loaded center of gravity complete vehicles needs to be restricted so it will meet CMVSS 135 and FMVSS 135 stopping distances. The laden center of gravity does not need to be specified as it is controlled within the CMVSS 135 and FMVSS 135 test procedure by specific instructions as to how ballast is to be placed (while height is not controlled, it is assumed that for test purposes it would be reasonable).For Body Builder’s use, the center of gravity location can be approximated by the following formula: d = [Wrc + Wrb + [(Hp)(Wp)/WB]] WB Wt h = [h1Wc + h2Wb + (h3)(Wp)] Wt d = horizontal distance from front wheels to completed vehicle center of gravity cm (in) h = vertical distance from ground to completed vehicle center of gravity cm (in) Wrc = rear component of bare chassis weight kg (lb) Wrb = rear component of body weight kg (lb) (continued on next page)Special Applications – SPPP – 2011Special Applications – SPPP – 2007

  14. 14. Special applicationS – FullSize K SerieS (4x4) SP–13 PAGE ‘K’ Series Snow Plow Best Practices 1 OEM Steering gear, Suspension and Powertrain Component mounting holes & associated OEM fasteners should not be used to attach Snow Plow Mounting equipment. 2) A suggested allowance of 10 mm minimumclearance to stationary OEM components example: Bumper Asm, Steering Box, Cooling System components is highly recommended. Note these components have varying positional tolerances. 3) A suggested allowance of 20 mm minimum clearance to OEM components subject to movement example: Steering Gear, Suspension (A-Arm, Axle, Strut, & Stab Bar asms) at full jounce is highly recommended. Note these components have varying positional tolerances. 4) Snow Plow & Associated Mounting Equipment should not exceed front axle available payload rating of vehicle as optioned. Plow Blade height, width & mass should be in accordance with Snow Plow Manufacturers recommended requirements for specific vehicle. 15mm hole for snow plow attachmentSpecial Applications – SPPP – 2011
