Complete suspension set

Everything you need to assemble or renew the suspension of your chassis, in a single kit

The complete suspension set SP110012 from Sloting Plus brings together in one bag the 14 pieces necessary to build or replace the suspension system of your slot car. Made from brass, aluminium, and stainless steel, this kit stands out for the quality of its materials and the inclusion of three spring hardnesses, allowing you to adapt the chassis response to different track conditions without the need to purchase additional components.

Kit Contents

The SP110012 kit includes exactly the following pieces:

• 2 special semi-threaded screws M2 × 11 mm total length (brass, Phillips head)
• 2 special semi-threaded screws M2 × 13 mm total length (brass, Phillips head)
• 4 special M2 nuts
• 2 SOFT springs Ø 3.1 × 10 mm
• 2 MEDIUM springs Ø 3.1 × 10 mm
• 2 HARD springs Ø 3.1 × 10 mm

In total, 14 units that cover a complete assembly.

Features and Highlights

• Phillips head screws: the specific head design facilitates tightening and loosening with a standard screwdriver, significantly improving usability compared to more delicate formats.
• Semi-threaded: the smooth area of the shaft acts as a movement guide, allowing the suspension to work correctly without the thread interfering with the travel.
• Three spring hardnesses included: SOFT, MEDIUM, and HARD with the same outer diameter (Ø 3.1 mm) and the same length (10 mm), so changing between hardnesses is immediate and does not require readjusting the rest of the geometry.
• Noble materials: brass in the screws, stainless steel in the springs, and aluminium in the complementary components. A common combination in competition chassis preparation.

Compatibility

According to Sloting Plus, this kit is compatible with most chassis and motor pods on the market. The use of the M2 standard and the most widespread spring measurements in the hobby make it valid for preparations on both proprietary and third-party chassis. If you have doubts about your specific motor pod, check the dimensions of the housing before assembly.

Assembly and Preparation

The assembly is straightforward: the semi-threaded screws pass through the motor pod and the chassis, and the M2 nut secures them from the opposite side. The spring is housed between both surfaces, providing the elastic cushion that absorbs the irregularities of the track. The differentiated lengths of the screws (11 and 13 mm) allow the kit to be adapted to motor pods of different thicknesses or to assemblies with varying distances between platforms.

To adjust the hardness without disassembling the entire set, simply replace the springs: as they share diameter and length, swapping between SOFT, MEDIUM, and HARD can be done in a matter of seconds.

Common Mistakes

• Over-tightening the nut: this blocks the suspension travel and nullifies its effect. The nut should be tightened but allow free movement of the screw in the semi-threaded area.
• Mixing screw lengths on the same axle: this generates asymmetry in the geometry of the motor pod. Always use the same length on each axle.
• Installing the HARD spring on tracks with a lot of profile: on circuits with pronounced curbs or sections with intense bumps, the SOFT spring offers greater grip and stability.

Frequently Asked Questions

How many cars can I prepare with this kit?

The kit includes components for a complete suspension assembly on a single car (two front or rear support points). If your chassis requires suspension at all four points, you will need two kits.

Are the screws flat-headed or rounded?

They are designed for a Phillips screwdriver, according to the official description from Sloting Plus. The exact profile of the head is not specified beyond the type of drive.

What is the difference between the 11 mm and 13 mm screws?

The 2 mm difference in total length allows adaptation to different motor pod thicknesses or configurations with greater or lesser separation between the mounting surfaces. Check your chassis measurements to choose the correct pair.

Can I use only the springs from this kit with screws I already have?

Yes, as long as your screws are compatible with the inner diameter of the spring (Ø 3.1 mm outer) and the length of 10 mm fits your motor pod. The springs are independent components and can be used separately.

What spring hardness is most recommended to start with?

The MEDIUM spring is a good starting point for most tracks and configurations. From there, try SOFT if the car loses contact in fast corners, or HARD if the motor pod sways excessively during braking.

Does this kit include assembly tools?

No. The kit includes exclusively the listed suspension pieces. For assembly, you will need a suitable Phillips screwdriver for M2 screws and a wrench or pliers for the M2 nuts.

The Sloting Plus SP110012 is a complete slot car suspension kit containing 14 pieces in brass, aluminium, and stainless steel. It includes two pairs of semi-threaded M2 screws (11 mm and 13 mm), four special M2 nuts, and three pairs of springs in SOFT, MEDIUM, and HARD rates — all sharing the same Ø 3.1 × 10 mm dimensions for easy swapping. Compatible with most slot car chassis and motor pods on the market. Ideal for club racing preparation and chassis tuning in 1/32 scale slot racing.
