Overview
Hot Racing's TTSP45FL is a linear-rate front shock spring set for the Losi 22S Sprint and related 1/10 dirt oval cars. Ten 45mm springs come in the pack, covering a 4 to 8 lb rate range, so you can work through setups across a night of racing without ordering one spring at a time.
Linear-rate springs compress at a steady rate through their travel rather than ramping up like a progressive spring. On a sprint car that makes the front end predictable: you feel the same spring resistance entering a corner as you do mid-corner, which makes a change you dial in at the shock actually show up the same way lap after lap.
Key Features
- Set of ten 45mm linear-rate shock springs
- Rate range from 4 lb to 8 lb for front-end tuning
- Linear rate for consistent, predictable compression through the stroke
- Sized for the Losi 22S Sprint front shocks
Performance Benefits
- A full rate spread lets you match the front end to track bite as the surface changes
- Softer rates add forward bite and corner entry steering on a slick track
- Stiffer rates hold the front up on a tacky, high-grip surface
- Consistent spring behavior makes each setup change easier to read
Usage Notes
- Front application; change springs in pairs and keep left and right matched unless you are deliberately staggering
- Note which rate you ran against track conditions so a good setup can be repeated
- Re-set ride height and droop after a spring change
