REAR SUSPENSION OVERVIEW (Rules are per the Unified Dirt Late Model Committee): Rear suspension designs and applications are constantly evolving. Although the intent of the rear suspension rules are an attempt to accommodate the majority of suspension and suspension component designs and applications currently being used in competition, the rules cannot be absolute. Any and all new designs or modifications to an existing suspension and/or suspension component must be communicated to and approved by the Series Director before
being used in competition. Rear suspension may utilize either coil or leaf springs. Rear suspension configuration of current designs know as 3 link, 4 link, cantilever, Z link, or swing arm designs may be used.

Rear Suspension Frame Mounts: All frame suspension mounts must be fabricated using magnetic steel. Frame suspension mounts may be a single or double shear configuration for mounting suspension components. Single shear frame suspension mounts must be a minimum of 1/4 inch in thickness. Double shear frame suspension mounts must be a minimum of 1/8 inch thickness on both sides of the mount. All frame suspension mount component mounting holes must be round and sized correctly for the fastener being used. Clearance between the fastener and the mounting hole must not exceed common industry standards for fastener clearance.

Axle Housing Mounts: Only one (1) axle housing mount per side permitted. Axle housing mounts may be a solid (welded) type or a floating type design. Final assembled axle housing mount must be one (1) piece mount. When a floating type mount is fabricated using two (2) pieces, the two (2) pieces must create a common one (1) piece pivot (barrel). The two (2) pieces must be fastened or welded together to prevent independent movement of the two (2) pieces. The axle housing mount must attach directly to the axle tube with clearance only to permit rotation of the entire mount. Fore, aft or vertical movement of the mount or the axle housing within the mount will not be permitted. Axle housing mounts may be fabricated from magnetic steel or aluminum. Mounts for suspension attaching (radius) rods must be an integral part of axle housing mount. The mounts may be single or double shear configuration. When using a single shear configuration, a minimum thickness of 1/4 inch for magnetic steel or 1/2 inch for aluminum is required. When using a double shear configuration, a minimum thickness of 1/8 inch for magnetic steel or 1/4 for aluminum is required. Dynamic movement of any mount other than movement created in normal suspension travel is not permitted. Mounting of any component(s) other than suspension attaching (radius) rods or shocks is not permitted on axle housing mounts.

Rear Suspension Attaching (Radius) Rods: A maximum of two (2) attaching (radius) rods per side will be permitted. Attaching (radius) rods may be fabricated from magnetic steel or aluminum. Attaching (radius) rods may be solid or tubular material. The material may be round or hexagon in shape. Spherical rod ends or steel clevises must be used at the end of each rod for pivoting, static length adjustment, and mounting. Bushings of all types will not be permitted. The final assembled attaching (radius) rod must not have the capability to change length dynamically by any means or devices. Spherical rod end sizes may be a minimum of a 5/8 rod end body with a 1/2 inch bearing to a maximum of a 3/4 inch rod end body with a 3/4 bearing. In all applications, the correct size fastener must be used when mounting the spherical rod end to a bracket (example: 1/2 fastener must be used with a 1/2 bearing and mounting hole). Attaching (radius) rods must mount directly to the frame suspension mount at the forward end and to the axle housing mount at the rearward end. All rear suspension fasteners must be magnetic steel with a minimum diameter of 1/2 inch. The use of grade 8 fasteners is highly recommended. All fasteners must be correctly sized for component and application of use.

Rear Droop Limiter: One (1) droop limited chain per side will be permitted. The droop limiting chain may incorporate bump stops and/or springs. The droop limiting chain must attach to a collar type mount on the rear axle tube and to the frame assembly directly above the lower mount. Droop limiting chains must be
mounted vertically. A droop limiter may utilize a bump stop or spring type connection. Any enclosed connector device may be considered as a shock absorber and counted in total number allowed.

Torque Control Devices: Lift arm assemblies and pull bars will be permitted.

Axle Housing & Rear Differential: The axle housing must be of the “closed tube” design utilizing “full floating” magnetic steel axle shafts. Center section of the axle housing must be manufactured of either aluminum or magnesium. Axle tubes must be one (1) piece. Axle tubes must be manufactured of aluminum or magnetic mild steel. Axle tubes manufactured of exotic, heavy materials are not permitted. The outside diameter of the axle tubes must not exceed three (3) inches. Axle tube internal inserts or external sleeves are not permitted. The addition of any ballast weight to axle housing is not permitted.

Axle Housing Mounts (Birdcages): The only materials allowed in fabricating axle housing mounts (birdcages) are aluminum or magnetic mild steel (no axle housing mounts of exotic or heavy materials). When fabricating axle housing mounts detail must be paid to functionality. The completed axle housing mounts (comparing right and left sides) must be as similar in design as possible. No Split Birdcages!

Rear Suspension Attaching (Radius) Rods: The only materials used to fabricate attaching (radius) rods permitted are magnetic steel or aluminum. Aluminum attaching (radius) rods may be solid or tubular material. Magnetic steel attaching (radius rods) must be tubular (maximum wall thickness of 3 16 inch). No spring rods or devices which change dynamically through the use of a spring to like device. 4 link mounts on chassis must be solid and cannot be sliding (flexible rod mounted to chassis must not move)

SPRINGS: Coil or leaf springs permitted. Coil springs must be manufactured from magnetic steel. Leaf springs must be manufactured from magnetic steel or approved composite material. Spring preload adjustments for coil springs must be made using mechanical adjusting nuts on shock body. Spring preload adjustments for leaf springs must be made using a mechanical adjusting device such as an adjustable shackle or threaded rod type mount. Other than spring dampening by the shock absorber, hydraulic, pneumatic, or electrically controlled adjusting devices, (static or dynamic) that affect spring preload or race car heights NOT permitted. No Stacking of Springs! One spring per shock! Spring Claim Rule is $125 and works under the same guidelines as Shock Claim Rule. One Standard Take-Up Spring allowed per shock (30 LB Max)

RADIOS: Radios ARE NOT legal (Track discretion). A working Raceceiver is mandatory.

TECH INSPECTION: Cars must have a “92” tire on right rear of car. All Shocks must be uncovered, and the hood must be removed (mandatory for pre-race inspection). Any item deemed as questionable or suspicious is subject to inspection and/or removal unless approved by SECA Technical Officials.
