Will the kit work on a GS 350 without AVS?

No. The kit relies on the factory Adaptive Variable Suspension to control damping, so TEIN lists it only for cars fitted with AVS. A GS without AVS needs a conventional coilover instead, and BA can advise which TEIN kits suit that car.

Can I adjust the damping by hand?

No. Damping on the TEIN Flex AVS Coilovers for L10 is controlled by the car through AVS rather than by a knob, and the kit is not compatible with TEIN EDFC. TEIN widened the range the AVS actuator works through, giving the system more room to adjust.

How low do the TEIN Flex AVS Coilovers for L10 set a GS 350?

TEIN recommends 1.0 to 1.8 inches below stock at both ends of a US GS 350. Full-length adjustment allows up to 4.0 inches lower at the front and 2.6 inches at the rear, and up to 0.1 inch above stock height at either end.

Will it fit a Japan-market GS 450h?

Yes. TEIN lists the Japan-market GS 250, GS 300h and GS 450h alongside the US rear-drive GS 350. Ride height figures are published only for the GS 350, and TEIN has not tested the F Sport model in Japan, so confirm fitment with BA first.

Can the dampers be serviced?

Yes. TEIN offers a replacement service that supplies a new damper body while reusing the upper mount, bracket and spring, and it can revalve the dampers or change their stroke on request. Ask BA for current service terms and timing.

Description

TEIN Flex AVS Coilovers for L10 Lexus GS 350 RWD

TEIN’s Flex AVS Coilovers for L10 Lexus GS 350 lower the rear-drive sedan while its Adaptive Variable Suspension keeps working, which a conventional aftermarket kit usually cannot do without disabling the system. TEIN set the damping range so AVS can use all of it, aiming for a flatter, more comfortable ride. The car decides the damping, not the driver, so anyone who wants to set the damping by hand should look elsewhere, and cars without AVS cannot use this kit.

Ride Comfort

TEIN’s Hydraulic Bump Stopper closes the base valve ports as the damper nears full compression, raising damping, while a relief valve trims any spike. On the GS this helps the car settle quickly after gaps in the road and keeps the rear seat comfortable when the car is carrying a full load. Conventional bump rubbers stay in place alongside it.

Features

Factory AVS keeps controlling damping after the car is lowered
Redesigned AVS Needle widens the damping range within the actuator operating angle
Full-length adjustment changes height with little effect on the ride
Twin-tube design for a long stroke and low reaction force
Hydraulic bump stopper tuned specifically for this model

About TEIN

TEIN was founded in Yokohama, Japan, in 1985 by former rally mechanic Hakaru Ichino, joined soon after by driver Yoshio Fujimoto. The team reached the World Rally Championship in 1989, and in 1995 Fujimoto won the Safari Rally in a Toyota Celica GT-FOUR, the first Japanese driver to do so. TEIN launched its own dampers in 1990 and came to supply around 80 percent of the dampers in the N1 Taikyu endurance series. TEIN USA has served the Americas from Downey, California, since 2001.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
