Need more stroke out of the tender? The H&R 4in Tall 50 lbs/in Helper Spring gives your coilover a taller helper with the same low-block, flat-wire design H&R uses across its 2.50" I.D. tender springs.
Why Choose the H&R 4in Helper Spring?
- 4in of helper height – rated at 50 lbs/in
- Trapezoidal wire – flat rather than round for a low block height and maximum travel
- Factory pre-blocked – won’t set or sag over time
- (hf) 54SiCr6 steel – H&R’s special lightweight spring alloy
- German-made – advanced materials and precision technology
Key Features at a Glance
- Height – 4in tall
- Rate – 50 lbs/in
- Fits – H&R 2.50" I.D. spring program

Notes
- Companion 2.50" I.D. main springs range from 6" to 18"; H&R rates them on average 15% lighter with 10% more travel than competitors' springs.
- For Euro spec cars like the Porsche GT3, H&R’s 60mm I.D. line spans 80mm to 300mm in length (25.4mm = 1 inch) and 25 N to 700 N in rate; N/mm x 5.709 = pounds/inch.
