Tune Your Ultima SB with Kyosho UM577B

The Kyosho UM577B Suspension Arm Set is a key upgrade for Ultima SB owners who want improved durability and more consistent handling. These arms are built to cope with off-road use while keeping installation and maintenance straightforward.

Built for Tough Tracks

Produced from robust materials, the suspension arms resist impacts and abrasion typical of club racing and bashing. Their geometry stabilises the chassis and helps deliver more predictable steering under load on rough surfaces.

Fitment and Easy Installation

The UM577B is made to match the Ultima SB mounting points so you can swap parts without complicated modifications. Use standard hobby tools for a quick replacement and return to running in minimal time.
Remark :
Due to limited stock availability, please notice that some Kyosho items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

How difficult is fitting the UM577B to an Ultima SB?

Fitting the UM577B is generally straight forward for anyone familiar with RC maintenance. The arms align with stock mounting points and can be changed using basic hobby tools. Take care with snap pins and bearings during refit.

Will these arms hold up for weekend racing?

Yes, the design targets off-road durability and consistent handling, making them suited to club level racing and practice sessions. Combine them with well-tuned shock settings for best results.

Should I expect to need extra hardware when replacing arms?

Check the product listing for included parts before purchase. Many arm sets are sold as bare arms, so have spare pins, screws and any bushings on hand to complete the job without delays.
