Shock absorbers Bilstein or Monroe

Bilstien 4600s are awesome. Had a set on an 00 tundra last damn near 200k miles

I always spring for bilsteins. They’re so much better than anything else.

ICON 07-14 FJ Cruiser/03-24 4Runner/03-23 Lexus GX, 2" Lift, Rear Spring Kit, ICON coil conversion kit, and Bilstein 5100s all around. Use OEM front coils. Fantastic ride quality.

I eventually ended up changing all 4 shocks to the B4's and it has been good too.

I have 5100s on my Tacoma and they made a great replacement to my OEM shocks. Kept it at factory height. Less nose dive when braking makes all the difference to me.

I just put new bilsteins on at 100k. So far so good.

I replaced mine around 130k on my 2015 with a pair of Bilstein 5100s, I would have done it way sooner if I knew how much of a difference it would make.

you can always put bilsteins on yourself (not too hard, put the 5100s and lift spacers/ blocks ((if off-roading, do not use front spacers, you will get coil bucket contact and a proper lift may be more expensive but its better on your performance and ball joints, i am mostly highway / town travel)) and it was done within a weekend with rental tools from the auto store).

Bilstein B6 monotube shocks work only with stock ride height springs. With a chassis as light as the IS300, they’ll give you a much stiffer ride than the other options. Some drivers like it; but you may worsen traction on roads in poor condition. Comfort will similarly degrade. Their main advantages are that they won’t fade in prolonged aggressive driving and they last a long time.

My experience with Monroe shocks over the last 42 years of working on cars. Monroe might have a lifetime warranty like the KYB has, accept even though the replacement is free, you still have the hassle of replacing the Monroe shocks every 2 to 3 years.
