Swift Springs Expands Assist & Helper Spring Line with New Flat Wire Tender Rates
New 50 lb and 100 lb Flat Wire Tenders Deliver More Tuning Options for Northeast Modified Racers
As suspension technology continues to evolve, racers are constantly searching for more precise ways to fine-tune chassis performance. To meet that demand, Swift Springs has expanded its Assist & Helper Spring lineup with two new Flat Wire Tender Spring rates designed specifically for Northeast Modified racing applications.
The latest additions include:
- 50 lb Flat Wire Tender – Part #: H025-152-050
- 100 lb Flat Wire Tender – Part #: H025-127-100
Manufactured entirely in-house using Swift Springs' proprietary HS5.TW wire, these new tender springs provide racers with additional setup flexibility while maintaining the consistency and quality Swift Springs is known for.
What Are Flat Wire Tender Springs?
Flat Wire Tender Springs are designed to work alongside the primary coil spring. Rather than changing the main spring rate, they help maintain spring preload and improve suspension behavior throughout the available travel.
In many modern racing applications, tender springs help the suspension transition more predictably while keeping the spring package properly seated during extension. The result is a more controlled and repeatable suspension package that allows racers to fine-tune performance for changing track conditions.
For Northeast Modified teams, these components have become an increasingly valuable tuning tool as chassis setups continue to advance.
New Rates Built from Racer Feedback
Like many products in the Swift Springs lineup, these new rates were developed after listening directly to racers and chassis builders.
The addition of the 50 lb and 100 lb Flat Wire Tenders gives teams more options when dialing in suspension behavior without compromising durability or consistency.
Both springs are manufactured using Swift Springs' proprietary HS5.TW material, produced in-house in Japan through the company's vertically integrated manufacturing process. This level of material control helps ensure the precise tolerances and repeatability racers expect every time they install a new spring.
Engineered for Today's Northeast Modified Setups
Modern Northeast Modified suspension packages continue to evolve, placing greater importance on predictable suspension movement and consistent platform control.
These Flat Wire Tender Springs are designed to complement today's coilover combinations by providing racers with additional tuning flexibility while maintaining dependable spring performance throughout race weekends.
Whether teams are refining existing setups or building new suspension packages, having multiple tender spring rates available allows for more precise adjustments as track conditions and chassis demands change.
