For a 2005–2015 Tacoma, Should You Use a Toytec 1.5-Inch Spring or Stock Coils on the Bilstein 5100 Fourth Clip?

SIMILAR HEIGHT; NO PROVEN RIDE WINNER
For a 2005–2015 six-lug Tacoma at stock front weight, the two listed setups target nearly the same lift: about 1.6 inches with Toytec 112-620-P springs on the lower Bilstein 5100 clip, or 1.55 inches with the OE coil on Bilstein circlip location #4. Do not stack the Toytec spring with the fourth clip: Toytec's own instructions limit that spring to the bottom or second-from-bottom clip. Neither maker compares which route rides or “performs” better.
The two published height claims are close—but they are different assemblies
Toytec's 112-620-P front-coil listing says that on a 2005–2015 six-lug Tacoma with Bilstein 5100s, its springs produce an average 1.6-inch lift at the bottom clip with stock front weight. It also warns that clip settings differ from Bilstein's OE-coil settings because the longer Toytec coil itself supplies lift. The product is not listed for five-lug 2WD Tacomas, and Toytec says results vary with vehicle configuration and weight. See Toytec's 112-620-P application and lift notes.
Bilstein's current B8 5100 24-324359 application includes 2005–2015 Tacomas and describes its snap-ring body as providing front lift with OE springs, depending on application. In Bilstein's mounting instruction, circlip location #4 is a typical 1.55-inch front lift; location #1 is stock height. That makes location #4 the like-for-like height comparison with Toytec's lower-clip 112-620-P setup—not a way to add 1.55 inches on top of that spring's stated 1.6 inches. Check Bilstein's 24-324359 application and its B8 5100 mounting instruction.
Do not combine the spring's lift with the fourth clip
Toytec's 2005+ Tacoma installation sheet is explicit: with Toytec/Eibach coils and Bilstein 5100s, do not adjust the assembly higher than about 3 inches of lift. It identifies the bottom setting as about 1.6 inches and the second setting from the bottom as the highest permitted clip, at about 3 inches with no added weight. The Bilstein guide's location #4 is above that second-from-bottom setting in its own numbered sequence.
Compatibility snapshot
The defensible buying decision is simple:
| If your actual goal is | Setup to choose |
|---|---|
| About 1.5–1.6 inches of front lift with Toytec's named spring | 112-620-P on the bottom clip |
| About 1.55 inches while retaining a sound OE front coil | B8 5100 24-324359 at Bilstein location #4 |
| A Toytec spring plus Bilstein location #4 | Do not combine them; Toytec's instructions do not support that setup. |
Neither source supplies a controlled comparison of damping, spring rate, ride comfort, tire clearance, alignment outcome, or durability between those two complete assemblies. “Which performs better?” therefore has no proven winner. The practical choice should start with whether the original coils and top mounts are serviceable and whether a specific spring-rate or load change is actually needed—not with an assumed ride-quality result.
Vehicle and installation limits remain material
This conclusion is limited to the named Bilstein front shock and Toytec spring on a 2005–2015 six-lug Tacoma with stock front weight. It does not approve five-lug 2WD trucks, listed TRD Pro/other 2.5-inch-shock exclusions, a truck with extra bumper/winch weight, different coils, spacers, altered control arms, or a different Bilstein part number.
Both manufacturers' instructions make installation a safety issue, not a casual height adjustment. Bilstein says suspension work requires a professional technician and requires caster/camber checking or adjustment after installation. Toytec likewise calls for a certified technician, warns that lift changes stability, and requires a front-end alignment after its installation. Do not use a spring compressor without the tools and training specified by the instructions.
Bottom line
For the narrow 1.5-inch-level goal, Toytec 112-620-P on the bottom clip and a stock-coil Bilstein 5100 at location #4 are similarly listed height options for the applicable 2005–2015 six-lug Tacoma. Pick one complete configuration, not both. The available manufacturer information does not support a stronger claim that either rides or performs better; get a qualified installer to verify the truck's actual load, parts, alignment and clearance. If permanent bumper or winch weight is present, start instead with the constant-load suspension framework and obtain a front-load-specific recommendation.
