Description
Overview:
This coil spring assister (MPN 763 604) is a load-support insert designed to fit between the windings of an existing coil spring to reduce sag under load and improve stability when towing or carrying heavy payloads. It is intended for vehicles with coil spring suspensions where the free gap between adjacent coils measures between 26 mm and 38 mm (approximately 1.02 in to 1.50 in) under normal static load. By occupying part of the coil gap, the assister limits excessive compression, helping to maintain ride height and reduce bottoming out. The insert is suitable for use on the rear or front axle as required, depending on the vehicle layout and loading pattern. It is a practical option for trade users preparing vehicles for trailer towing, plant transport duties, or frequent heavy van loads, where occasional extra support is needed without changing the original spring hardware. The assister is a straightforward fit with basic hand tools and can usually be installed without dismantling the suspension, making it a convenient workshop or on-site solution for fleet maintenance and service operations.
Key Features:
- Suits coil springs with a 26-38 mm (1.02-1.50 in) gap between adjacent windings
- Helps reduce suspension sag and improve support under towing or payload conditions
- Assists in maintaining ride height and reducing bottoming on rough surfaces
- Non-metallic insert designed to sit securely between existing coil windings
- Can be installed with basic hand tools; typically no spring removal required
- Suitable for use on front or rear coil springs as the application demands
- Aids stability and reduces excessive body roll when carrying variable loads
- Practical retrofit solution without replacing original springs or dampers
Typical Applications:
Used on cars, vans, 4x4s and light commercial vehicles that tow trailers or carry heavy or variable loads. Commonly fitted to rear coil springs on towing vehicles to support drawbar and nose weight, or on front/rear axles of service vans and utility vehicles engaged in plant transport, site work and general fleet duties where additional spring assistance is beneficial.
