Medium hardness suspension spring - long ø medium

The right balance between stiffness and absorption for your slot suspension

The TT927 by Tectime occupies that intermediate point that many tuners seek: not too soft for the chassis to sag, nor excessively stiff to lose contact with the track. With medium hardness, long length, and medium diameter, it offers a versatile working range that adapts to different suspension configurations in competitive or serious tuning slot cars.

Main features

• Hardness: medium — balance between irregularity absorption and response firmness.
• Length: long — greater useful suspension travel and more adjustment margin through compression.
• Diameter: medium — compatible with the most common mounts in slot suspension chassis.
• Contents: pack of 4 units.
• Reference: TT927 / Tectime.

Function and performance

The hardness of the spring directly determines how the car responds to changes in elevation, chicanes, and track irregularities. A medium hardness long spring allows for a more generous suspension travel, which is particularly useful on tracks with some elevation or in configurations where maintaining all four wheels in contact with the surface for as long as possible is desired.

The medium diameter makes it compatible with a wide range of front or rear suspension systems where long fine pitch springs have their natural place.

Installation and preparation

When installing or replacing suspension springs, it is advisable to work with a set of springs of different hardnesses to compare behaviours on track. The TT927 is a good starting point if you are coming from a soft spring and notice excessive chassis roll, or if you are starting from a hard one and looking to regain grip on corner entries.

Supplied in a pack of 4 units, you have enough material to equip a complete axle or to test asymmetrical front/rear configurations and find the optimal setup for your circuit.

Compatibility and applications

As there are no additional technical data from Tectime regarding specific compatibility by chassis brand, we recommend checking the exact measurements (inner diameter, outer diameter, and total compressed/free length) against the specifications of your chassis manufacturer before installation. The Tectime spring range is aimed at tuning and setup of 1/32 scale slot cars.

Frequently asked questions

How many units are included in the pack?

The TT927 pack includes 4 springs with the same characteristics: medium hardness, long length, and medium diameter.

What is the difference between a long spring and a short spring in slot suspension?

A longer spring offers greater suspension travel and allows for more progressive adjustments through preload variation. Short springs are stiffer in practice even at the same nominal hardness, as they operate in a smaller compression range.

What type of track is medium hardness most suitable for?

Medium hardness is a good universal option: it works well on club plastic tracks with joints between sections and also on wooden circuits with smoother profiles. It is the usual starting point before fine-tuning towards more specific hardnesses based on observed rolling behaviour.

Can I combine different spring hardnesses on the same car?

Yes, it is a common practice in tuning. Some drivers use softer springs on the front axle and harder ones on the rear (or vice versa) to control the car's balance. The TT927 can be combined with other references from the Tectime range to explore those configurations.

Can it be used on any chassis with suspension?

It depends on the spring mount of the chassis. It is essential to check that the medium diameter of the TT927 fits into the intended mount before installation. Consult your chassis specifications or contact us if you have any doubts.

The Tectime TT927 is a medium-hardness, long, medium-diameter slot car suspension spring, supplied in a pack of 4 units. Designed for 1/32 slot car chassis tuning and setup, it offers a balanced response between absorption and rigidity — ideal for club racing, competition preparation, and chassis fine-tuning on both plastic and wooden tracks.
