OME International Catalogue

Terminologies & Explanations GUIDE TO SELECTION Please note most suspension development has been carried out on Australian specification models. Therefore, some differences may exist between the same model in another country. Overseas customers will need to make allowances for these possible differences. Supplying all items shown on suspension selection charts will ensure the system can be fitted, however, there will be vehicles which will not require all items, eg. trimming kits, caster kits, all U bolts shown, etc. Actual, individual vehicle requirements can only be determined when the suspension system is fitted. GVM - GROSS VEHICLE MASS: Set by the vehicle manufacturer and is determined by brake, axle, differential and tyre specifications. Exceeding GVM ratings can have legal and safety implications and is not recommended. LOAD RATING: REAR: The explanations below indicates the passenger and load weights that will provide optimum ride and handling. LIGHT LOAD: Full passenger load with luggage weights up to 150kg. FRONT: Weights shown are maximum permissible loads with regard to accessories fitted, eg. Bull bar, winch, dual battery, etc. MEDIUM LOAD: Full passenger load with luggage weight varying from 200kg to 350kg. CONSTANT LOAD: The minimum constant load shown on selection chart is required for optimum spring performance. Please note: These loads are approximate only. Refer to individual vehicle selection for load specifications. HEAVY LOAD: Full passenger load with luggage weight varying from 350kg to 500kg. LIFT HEIGHT: Is shown as a guide only and equates to the amount of lift over the vehicle's original ride height. This amount can vary from vehicle to vehicle. OE: Original Equipment, as supplied by the manufacturer of the vehicle. SHOCK ABSORBERS: Where two part numbers are given for the same application the part with the asterisk (*) indicates the shock absorber with the firmer ride. SPRING BUSH: OME polyurethane spring eye bushes on installation must only be greased in the bore and on the flange area and regularly thereafter with OME polyurethane grease. STEERING STABILISER: Designed as a larger capacity replacement for the OE part and incorporates 50/50 neutral valving. CASTER KIT: The OMECA77B, CALR1 and CALR2 kits consist of 4 eccentric bushes which are pressed into the leading arms of the vehicle. This will induce positive caster into the front geometry. LEAF SPRINGS: A & B springs can be used to compensate for uneven vehicle weight distribution. Springs marked "A" have a greater camber height than springs marked 'B'. 'A' type springs are generally fitted to the driver's side and 'B' springs to the passenger side. Where two spring rates are listed for one spring the spring is progressive. GEARBOX PACKER KIT: Designed to space down the gearbox cross member from the chassis to reduce tail shaft flange angle thereby reducing driveline vibration. GREASABLE SHACKLES: Replacement for original shackles allow easy regular greasing of polyurethane spring eye bushes. COIL SPRINGS: A & B springs are used to compensate for uneven vehicle weight distribution. 'A' type springs are generally higher in free high than the 'B' spring. Individual coil specifications are listed in the back of this publication. Where two spring rates are listed for one spring the spring is progressive. TRIM PACKERS: The prime purpose of a trim packer is to correct slight vehicle leaning. VEHICLES WITH LEAF SPRINGS UNDER SLUNG: Trim packer when fitted will reduce suspension height. VEHICLES WITH LEAF SPRINGS OVER SLUNG: Trim packer when fitted will increase suspension height. VEHICLES WITH COIL SPRINGS: Polyurethane trim packer main purpose is to correct slight vehicle trimming problems and will increase ride height when fitted. Vehicle Region: Domestic (AUS) International (USA) Global Indicates the suspension was developed in Australia on an Australian vehicle, compatIbility outside of Australia will need to be confirmed. Indicates the suspension was developed in the USA on a USA vehicle, compatability outside the USA will need to be confirmed. Indicates the suspension was developed in Australia on a Global platform, it is still recommended to confirm compatibility outside of Australia. 4 OME INT CAT. NO.50 OCTOBER 2022
