Hey Joe (or anyone else) - What's the difference between the TRD Pro suspension and normal 5100s set on Eibach Springs? Outside of the rear remote reservoir its not obvious you're getting much extra for the money.
Are they valved (tuned) differently than your off the shelf 5100s? Are the front springs not available directly from Eibach?
I want this setup but the cost seems steep relative to other 5100/Eibach setups, and those other setups include rear coil lift springs. I can't justify the extra cost for "just" the remote reservoir and TRD badging.
Am I missing something?
Thanks all!
<Apologies if this topic has been discussed already. I searched but didnt find a clear explanation -- can't hurt to have it answered in multiple places.>
Using Google often finds stuff in this forum that the regular search will not.
It only took about 10 seconds for me to find this info (in this same thread), so here is part of your questions answered....you will need to get info on the valving and other dimensions for the 5100's...
The part #'s for the springs are in this forum if not in this thread, so just look around abit.....
High Performance TRD Suspension System
Professionally-tuned by TRD suspension engineers for high performance to Toyota’s exacting standards for ride quality and durability, both front and rear suspensions feature larger Bilstein® monotube shocks that hold additional shock fluid, as well as larger digressive Bilstein® pistons (60 mm front/46 mm rear, versus 32 mm original equipment front/rear) that gave engineers greater surface area for tuning valving profiles. The front and rear original equipment sway bars, end links, and bump stops are retained.
Front suspension details: TRD-tuned 2.5-inch Bilstein® 5100-series independent coil-over-shock type suspension, TRD-tuned Eibach® springs, and factory stabilizer bar, end links and bump stops.
TRD-tuned Eibach® springs with decreased spring rates (softer-than-stock) improve ride quality over harsh terrain and gives a 1-inch higher ride height, for a level front to back appearance that gives better front ground clearance when out on the trail off-highway.
Larger 2.5-inch shocks (similar in size to those used on heavy-duty industrial vehicles) with digressive valving are matched to the softer spring rate for enhanced overall characteristics operating off-highway in the dirt. Larger, more rigid 18mm shock shafts add component strength (original equipment shafts are 12mm).
The new shocks have also been engineered with a longer-stroke, to give an additional 1-inch of extended, or “down”, wheel travel for enhanced articulation capabilities when off-roading.
The larger 2.5-inch shocks houses a greater oil capacity than stock equipment; the increased amount of oil means the shocks can better dissipate heat and avoid cavitation created from working the shocks hard off-
road. This results in a predictable suspension that consistently works over longer periods of time in some of the most extreme situations and environments.
Rear suspension details: TRD-tuned 2.0-inch Bilstein® 5100-series shocks with remote reservoirs, and factory rear coil springs, stabilizer bar, end links, and bump stops.
The enhanced rear suspension features larger-than-stock 2.0-inch shocks with remote-mounted external reservoirs that also house a greater-than-stock shock oil capacity, equivalent to that of a larger 2.5-inch shock, but inside of a more compact package. The increased amount of oil means that the shocks can better dissipate heat to help avoid cavitation created from working the shocks hard off-road. This results in consistent, predictable suspension operation that keeps on working as designed in the most extreme situations and environments.
The upgraded Bilstein® rear shocks use larger 46 mm pistons with more valving surface area, an improvement over the 32 mm original equipment pistons.
The shocks have also been engineered to provide an additional 1-inch of extended or “down” wheel travel for enhanced articulation capabilities when off-roading.
